BasicCAD

• OBJ, PLY, GLB and more — open a scan with its colors: OBJ with its MTL and textures (or a .zip of them), vertex-color OBJ and PLY, ZBrush polypaint, GLB / glTF from Polycam, Luma, Scaniverse and AI generators, and STL
• Real size, the right way up — metre files are spotted and converted, set any size or click two points and type their real distance; lay it flat or pick the face to put on the bed
• Repair for printing — floating debris out, holes filled, noise smoothed, simplify to any triangle count, and Make solid rebuilds a broken scan as one closed surface
• Cut, flatten, hollow, base — flatten the bottom or cut with a plane and close it flat (with a live preview), hollow it with a wall for resin, add a display base
• Print colors for your AMS — the texture becomes 1–16 print colors, or matches your own filaments; specks merged, color edges sharpened from the texture, a paint brush to touch up
• Export or edit in CAD — a 3MF that opens in color in Bambu Studio, Orca and PrusaSlicer, STL, OBJ (print colors, the original texture or vertex colors) and PLY — or open it as a CAD body with its colors and sketch on its flat cut. Any part can now be exported as OBJ too.

• Recognize features by default — the STL, 3MF and STEP dialogs now open on two simple cards, Editable features (recommended) or Solid body, with everything else tucked under “More options”
• Watch it work — the part appears the moment you drop it, then one progress bar shows the real stage, elapsed time, an estimate of the time left and a live log, and each feature lights up on the part as it’s recognized
• Skip any time, no frozen tab — “Skip – keep the solid” works at every stage, the planning and every risky test build run in the background, and a time limit hands you the solid instead of grinding on
• A clear finish — a green “DONE!” banner with the final match appears only once everything is truly finished, and under 99% it recommends the solid body
• Features ⇄ Solid body — an import keeps both the recognized features and the original solid; a switch at the top of the design tree (or a right-click) flips between them, so you can still cut, fillet and sketch on the STL directly
• Always the best reading — Editable features ends as features, keeping the best of every attempt (closest to 99.5%, then the fewest features); sculptures and other free-form meshes keep the exact solid, with their large flat areas as faces you can sketch on

• Outlines a person would draw — mesh outlines become the fewest lines, arcs and circles, and parts are read as extrusions, cuts and pockets from every side, with a gentle taper as one loft (a filament clip went from 1,352 sketch entities to 18)
• Real fillets and chamfers — rounds and chamfers are taken off the mesh first and come back as native Fillet and Chamfer features on the built edges, whole rings at a time, at sizes the kernel can actually build
• Turned parts, pipes and twists — round parts become one Revolve, a bent tube becomes Sweeps along its path with exact arcs at the bends, and twisted pillar cages such as chess pieces get a Twist feature with the measured angle
• Threads, tapped holes and knurls — fine, coarse and multi-start threads become Thread features, tapped holes become Hole Wizard holes with their lead-in chamfers, and knurls or ribs become the new Knurl feature
• Patterns, shells and lettering — repeated holes, studs and walls become Linear or Circular Patterns, thin-walled bins become a Shell with their details on the walls, and raised or engraved text becomes one editable Text feature, matched against 2,000+ open fonts
• Multi-body meshes handled — shells saved in one file that touch or overlap are merged into one body (a 26-shell press base became one part), inside-out cavities are turned the right way, and loose slivers are left out
• Measured, not guessed — every result is measured exactly against the original mesh, and a final pass adds only clean features that pay off: Press Base 99.95%, Press Leg 99.97%, a threaded rod 86% → 99.5%, a steering-wheel spacer 100% in 4 features

• Open Fusion 360 files — File > Import reads .f3d and .f3z designs with exactly the bodies and placements Fusion shows; multi-component designs come in as an assembly, and Editable features replays Fusion’s own timeline wherever it matches
• STEP that never hangs — STEP conversions test every risky fuse, cut and revolve in the background first and leave out one that would never finish, instead of freezing the tab
• Smarter STEP conversions — the analysis runs in the background, multi-part files import per part or as an assembly, gears and lettering are recognized, and a part that converts below 90% keeps its exact solid
• OpenSCAD libraries built in — 32 popular libraries (BOSL2, BOSL, MCAD, NopSCADlib, threads and more) are served by BasicCAD itself, and SCAD conversions turn threads into Thread features and ribs into patterns
• Up to Face on imported parts — Up to Face and Up to Next on an imported part stop on the face you picked or the far side of the wall, and never lose the body

• Your design travels with the file — “Include the BasicCAD design” (on by default) tucks the editable design inside STL, 3MF and STEP exports; drop the file back in and it opens as the full editable part, while a file another program changed imports as a plain mesh
• 3MF colours come in — Bambu Studio, Orca and PrusaSlicer paint (brush strokes too), per-part filaments and colour groups import onto the solid and survive cuts, splits, repainting and 3MF export
• Watertight 3MF, in the background — every body is written fully closed (a Benchy import went from 547 open edges to 0) while each triangle keeps its colour, and big exports no longer freeze the tab
• Mesh fillets in your STL — a fillet the exact kernel can’t build is rounded on the mesh in the background with a working Cancel, and now comes out round in the exported STL too
• Inch parts import at full detail — STL and 3MF files build the same full-detail solid whatever units the document uses
• Windows thumbnails for STL and 3MF — Show Thumbnails in Windows 1.2 previews .stl and .3mf files as well as BasicCAD files, with a colour for STL previews, and is now code-signed

• Split to Print — cut an oversized part, or any STL, 3MF or STEP, into bed-sized pieces with printable joints; seams steer around text and detail, and you can set the number of pieces or draw your own cuts point by point or freehand
• Print-Ready Holes — choose how the part sits on the bed and every hole is checked: teardrop or flat-roof tops for sideways holes, size compensation, bed chamfers or bridge layers for the rest, with a “Why?” diagram for each rule
• Support Fins — breakaway fins built into the model so a part prints tilted with slicer supports off: a 3 mm flat foot, overhang ribs, side fins and a bed pad, based on the open-source Support Fins project
• Pixel Fidget as a feature — a Pixel Fidget now sits in the design tree and regenerates when you edit the part, with strength and range-of-motion settings
• Knurl — a new tool that knurls a round face with diamond, straight or spiral grooves, and stays editable afterwards

• Snaps land where you point — at any zoom, edges behind the sketch plane no longer pull a click up to 128 px away; snap dots are about 65% smaller and stay the same size on screen, and a new Snaps menu and Snapping guide name every snap
• Rim points every 15° — circles and arcs snap at their compass points at any size and at every 15° once you zoom in close enough to aim
• Dimensions move what you expect — a new dimension between two shapes moves the second one, never both, and one blocked only by a centring tie asks whether to remove it, with a diagram of the sketch
• Offsets that stay offset — an offset now has its own relation and an editable offset dimension, and an edit that clashes only with a duplicate dimension turns that one into a reference
• Tidier dimensions — labels are laid out in free spots instead of on top of each other, stay beside the part when you scale it down, angle dimensions go where you click, and a Dims/Tidy toggle sits by the DOF chip
• 3D sketch lines follow the axes — on every draw plane, On Face included (X now switches planes), and shapes drawn On Face stay on the face when you dimension the path
• A 2D | 3D sketch view — the Finish bar’s switch hides the part and squares the view to the sketch, sketch lines are a deeper blue and green that read on white parts, and Edit Sketch frames like the 80% button
• 2,000+ fonts — the Text panel’s new “More fonts” search reaches 2,077 open font families, each loaded only when you pick it

• Fillets round only what you picked — a fillet after another fillet rounds exactly the edges you chose instead of running down neighbouring edges, and its preview no longer draws seams
• Chamfers that meet — two chamfers that use up the face between them build one clean ridge, and Max finds that exact size
• Max uses the whole face — Fillet and Chamfer Max take the exact limit and prove it with a real build, instead of leaving about 10% of the face standing
• Easier edge picks — when picking for a fillet or chamfer, an edge wins over the face behind it, and right-click offers Select Other
• Sturdier rebuilds — reference planes tangent to a cylinder follow it, editing a loft’s section rebuilds the loft, shells work on thin rings, and a fillet blocked only by a split face builds at full size
• A clearer Extrude/Cut panel — big Add / Cut / Intersect buttons, colour-coded settings and a slimmer panel, so the part barely moves while you extrude
• Faster edits — editing or cancelling a feature on a converted part replays only what changed (one pattern edit went from 1.8 s to 0.05 s)

• A multithreaded geometry engine — the new engine build is now the default everywhere, running in parallel where the browser allows, and an engine bug that could hang some files for good is fixed
• A much faster website — the published app’s interface runs up to 15× faster and its background workers about 13× faster, with the same protection
• See what a feature made — hovering a row in the design tree lights up the faces that feature actually made on the part, in a blue x-ray highlight, and hovering a sketch shows the sketch
• Smoother round faces — curved faces now shade from their exact surface, so vases, bottles and turned parts look truly round up close
• Touchpad control — with the BasicCAD style, Ctrl + move rotates, Shift + move pans and Ctrl+Shift + move zooms
• Assembly part menu — right-click a component to Edit Part or Export Part (STL, STEP, 3MF, OpenSCAD or .cadjson), Back to Assembly skips untouched parts, and saved assemblies keep their imported meshes
• Steadier everywhere — Sweep no longer freezes the published site, and new guide pages with real screenshots are live on basiccad.xyz

• Live Session — edit one part together in real time: “Start a live session” gives you a join code or invite link, and guests connect straight to you, peer to peer
• Pixel Fidget & Twist Slide — two print-in-place fidget makers that turn the open part, any STL, 3MF or STEP file, or a built-in shape into a toy, with live previews
• Edit Face & export outlines — right-click a face to start a sketch on it, or export its exact outline, or a section through the part, as DXF or SVG at true size
• STEP and SCAD to features — STEP imports rebuild fillets, chamfers and threads as real features, and an OpenSCAD file’s variables become Parameters that drive the converted features
• Sweeps that follow a sweep — run ridges, sleeves or bores along an existing sweep’s path, cut a sweep that starts the part, and text cuts honour their direction and end conditions
• Make Mold, much faster — molds of imported meshes build 12–100× faster, with a Part/Mold switch, a draggable parting plane and a pour inlet

• Type dimensions while you draw — value boxes appear as you draw a shape: just type, Tab locks the value with a gold padlock and moves to the next box, Enter commits the exact size
• Tab stays in your dimensions — in a dimension box Tab accepts the value and opens the next dimension (Shift+Tab the previous), and it never wanders off around the page
• One-click corner rounds — the sketch Fillet and Chamfer tools round a corner with a single click on it
• Live sketch text — text in a sketch updates with every keystroke and setting, and the 3D text follows when you press Enter
• Better 3D sketching — part snaps only within 5 px, an X/Y/Z axis lock, angles between path lines from any view, and shapes snapped to a path point land on it and follow its dimensions
• Sharper tracing & SVG — the Trace Wizard fits exact straight lines (even a QR code), finds the background and edges by itself and defaults to the most faithful fit; SVG imports keep faint overlays, bring in text and lose the phantom circles

• Resize the side panels — drag the inner edge of the design tree or the Properties column (double-click resets it), and collapse the ribbon Word-style for more room
• Laptop touchpads — two-finger swipes orbit, pinch zooms toward your fingers and Shift+swipe pans, while the BasicCAD scroll wheel only ever zooms
• 3D mouse roll — a SpaceMouse can now roll the view and picks its rotation centre automatically; the Part Rotate button, which moved the part instead of the view, is gone
• Correct 2D drawings — drawing views are no longer projected from the wrong side (Top had shown the bottom), with a colour mode, a rotate menu and double-click editing
• An honest Properties panel — its rows now match what each feature really uses, and Enter commits values changed with the arrow keys or wheel
• Watch the showcase — a link under the examples plays a live CAD showcase built through the real app, and the home page now links the Terms of Use

• No mesh is too dense — STL and 3MF files of any size now import, simplified automatically when needed, instead of asking you to decimate and retry
• STL parts reopen instantly — a part with an imported mesh reopens without redoing the conversion, and imported fillets display smoothly without stray dashes
• Threads that fit — a thread picked on a shaft now defaults to Cut with a tip chamfer and runout, and older parts show an “As saved / Updated” preview so you choose
• Edit an extrude in context — editing a Boss or Cut rolls the part back to before it and shows its sketch with the regions ticked
• Cleaner outlines — edges between curved faces are drawn at any angle, face outlines are no longer traced twice, and a circle drawn on a half-round face stays where you drew it
• Safer and steadier — names in files are always shown as plain text, Academy 1.11 and picture tracing no longer freeze the published site, Undo after New Part can’t bring the old part back, and opening an assembly leaves no ghost geometry

• Tier 1 is now one project — eleven lessons (about 55 minutes) take you from a blank part to a printable fidget spinner on a standard 608 bearing, with a hub, three arms, bearing pockets, chamfers and a snap-in cap
• Guided final assembly — lesson 1.11 seats the bearing and both caps with Concentric, Distance and Coincident mates, and the faces to click glow gold
• Pick up where you left off — each lesson continues your own part from the one before; if it isn’t at the right stage a matching checkpoint loads, and “Load checkpoint” swaps one in anytime
• Watch the kit grow — the Academy home shows a 3D Spin Kit that lights up piece by piece, and every finished lesson shows what you just made
• Side Quests — favourites like Copy Machine, Drop the Logo, Ring Master and Relations Roundup move to a new Side Quests shelf, joined by a new Boss: The Lucky Die
• Clearer coaching — demo captions stay up twice as long and fit their box, Gear Factory takes one step per setting, and Paint Shop’s demos match the real Color panel

• Text follows any curve or edge — “Pick a curve or model edge…” highlights what you hover and accepts any sketch curve, face outline or model edge, so a circle’s rim is finally easy to pick
• Place curve text by dragging — drag along the curve to slide the text or across it to switch sides, with snaps to the centre, the ends and quarter turns (Ctrl frees it)
• Live text sizing — font size, spacing and gap redraw as you type, press the arrow keys or click the new −/+ buttons, and Fit works with every font
• Centre snaps you can see — face and shape centre snaps are now a violet dot with a dark outline (the old yellow one vanished on white parts), and you can recolour them in Settings
• Sketch framing clears the toolbars — the 80% button, V and the re-fit after typing a dimension frame the sketch in the space not covered by bars and panels, so every label stays visible
• Lines land on round rims — line ends snapped to a round face’s edge sit exactly on the circle so the areas they close off show up as profiles, and the band between two tangent-joined circles is its own region

• STL export in the background — the page stays responsive while threads and wrapped artwork are baked, and “Generating STL…” shows each stage with a Cancel button
• Big multi-body parts stay responsive — wrapped labels now engrave in the background, each into only the body it touches, so a 92-body test part with 46 labels loads in about 20 s instead of freezing the tab
• Rounder small parts — parts under about 200 mm across display with a finer mesh (a 22 mm cap rim goes from 23 to 83 facets), while exported STLs are unchanged
• Fillet corners after a cut — a cut that ends on a round face’s edge no longer leaves a hidden sliver that blocked full-size fillets and chamfers on that corner
• Face sketches stay put — if an earlier cut removes the face a sketch sits on, the sketch keeps its saved plane instead of jumping to another face
• Quicker mating, cleaner painting — Enter adds a mate as soon as both picks are made, round edges highlight as true circles, and a click in Color mode only paints the face

• Old threads and fillets restored — models saved before recent changes rebuild exactly as saved again, with their original thread shape and fillet-chain results
• First opt-in upgrades — File Compatibility in Settings now offers “Complete fillet chains” and “Fuse raised threads for export” for older files, and Un-upgrade puts a file back exactly as saved
• Fewer surprise rebuilds — fillets and chamfers no longer spill onto a neighbouring rim, and a face sketch reused by a second extrude no longer flips to the underside

• Make Mold — a new two-piece mold maker: let Auto pick the parting plane or choose one, set wall and backing thickness, alignment pins and cavity taper, with Advanced options for inlets, vents, shrinkage and draft checks
• Split & Move — cut a part with a plane or a closed sketch (drag the plane’s corners to cut just one area), then move the pieces apart or extend the cut section to lengthen the part
• Reference planes you can keep — Ref Plane saves each plane in the design tree; resize or move it with its handles, double-click to edit it, and sketches on it follow along
• External Geometry — bring the body into your sketch as linked violet reference geometry (a section through the part, edges projected onto the plane, or its outline) that updates on every rebuild
• Extract Bodies — tick bodies in a multi-body part and open them as a new, still-editable part or download them, and dropping a multi-body file offers “Choose bodies…” in about half a second
• Wrap Text/SVG rebuilt — a 3-step wizard places text, an SVG or a traced picture on a flat or round face, then engraves, embosses or repeats it as a texture, watertight for your slicer
• Trace Wizard upgrades — a new Edge trace tool, drag or delete any point, the first dimension scales the whole tracing, and the tracing reopens from its row in the design tree

• Hole Wizard options that combine — Counterbore, Countersink, Tapped and Heat-set insert are now checkboxes sharing one size, and each hole gets a draggable centre point you can dimension to model edges (press D)
• Edit holes in place — double-click a hole on the model to edit it, holes follow when the part changes, and a tapped hole’s threads now sit under it as one tree row
• Threads that start and stop where you choose — the Thread dialog adds Start from (either rim, or a picked edge or face), an end condition and “Keep length with offset”, with cleanly trimmed ends
• Find the fastener, print the mate — right-click a thread or tapped hole to see which standard fasteners fit, or make a matching threaded dowel or hole as a separate test part
• Snugger printed threads — new threads default to a 4% tighter print clearance, while threads in files you’ve already saved keep their own value
• Threads on multi-body parts — a bolt sitting in its hole as a separate body keeps each thread on its own body, and one failed thread no longer fails all the others

• Dimension to the model from any plane — sketches on faces, datums and reference planes can snap and dimension to model edges, corners, hole centres and cylinder axes, and the dimension moves your sketch, not the model
• Math in every number field — type 10+5, (4+1)*2 or 30°+15° into extrude depth, draft angle, dimension boxes and every other number field, mixing units freely
• Snaps measured in screen pixels — alignment and square-to-edge snaps only grab within about 4 px, so inch parts no longer jump half an inch to a corner, and a new H/V snap strength setting tunes straightening
• Guides that explain themselves — alignment guides are colour-coded and labelled (centre, midpoint, corner, origin), a Snap choices card lets you Tab between overlapping snaps, and Enter ends a line chain
• Dimensions that stick — clicking away from a dimension box now commits the value like Enter, labels are gold on small dark boxes that spread apart, and angle dimensions measure on your cursor’s side
• Face sketches the right way round — clicking a face now uses its true outside, so sketches on faces no longer come out mirrored, offset or seen from inside the part

• Smarter up-to extrusions — Up to face measures from your profile (no more accidental 8-metre beams), Up to next and Up to body stop on the faces they actually meet, and end conditions are one click
• Revolves keep true curves — arcs and splines in a revolve profile make smooth surfaces instead of faceted bands (a sample bottle went from 36 faces to 6)
• Fillets that round every edge — a fillet after another fillet now rounds every selected edge, including ones the earlier fillet created, or warns you instead of showing a green tick
• Pattern axes you can pick and re-pick — Circular Pattern takes its axis from a straight edge, sketch line, sketch circle or vertex, with Re-pick and Flip at any time
• Cuts that do what you picked — drafted round cuts and face-outline circles cut correctly, a cut that would delete the whole body is refused, and a split body keeps one colour unless you tick “Different color per body”
• Edits that don’t break features — changing a polygon’s side count or a sketch pattern’s count keeps the cuts built on it working

• Imports keep the solid by default — STL, 3MF and STEP imports start as a solid you can sketch on, cut and fillet right away, with feature recognition one click away when you want it
• Oversized meshes import — STL and 3MF files over 250,000 triangles are simplified automatically instead of refused, and sketching on a flat face traces its outline instead of every triangle
• Export exactly the bodies you want — the STL, STEP and 3MF dialogs let you tick bodies by preview, name or engraved text, and threaded multi-body parts export in parallel (584 s down to about 11 s on a 92-body test part)
• Deforms carry into your files — Bend, Taper, Stretch, Twist and Deform now show bent outlines and are included in STL and STEP exports
• Exports match the screen — exports and previews respect the rollback bar, and “Separate STL per body” now works for bodies that touch
• Real colours in Bambu Studio — painted 3MF exports now open in Bambu Studio in their actual colours instead of default filament colours

• A compact, modern ribbon — tabs share one header row with Undo/Redo, Find a Tool (Ctrl+K), units, View, Settings and Load Recent, tools fit in 2–4 resizable rows, and a Classic ribbon style brings back the old layout
• Make the ribbon yours — Customize hides tools you don’t use and reorders them by drag with a live preview, and right-clicking any tool lets you change its shortcut
• White parts, calmer previews — parts now default to white with brighter lighting, and added-material previews use a soft blue-grey that doesn’t flicker
• See, edit and test mates — hover a mate to light up the mated pair, change its type or value right in the tree, and drag a component to see how its mates let it move
• Easier assembly building — Load Recent inside an assembly inserts the part you pick as a component, and Insert Component lists your recent parts with thumbnails
• Saved files keep their meaning — files now carry a format version, and File Compatibility in Settings decides whether older files pick up future behaviour changes (by default they open exactly as saved)

• A week offline — the installed app keeps working for at least 7 days without internet before asking you to reconnect, and imports, examples and Academy parts now work offline too
• Tablet pen support — a stylus such as Apple Pencil now works like a mouse, a long-press acts as right-click, and a floating button opens pen shortcuts for Esc, Enter, Delete, Undo and more
• A mobile landing page — on a phone, basiccad.xyz now opens a mobile page where you can spin real models, pull apart the Grand Clockwork and watch an STL get a new mounting hole
• Heavy parts load faster — the geometry engine does less work per operation, multi-body parts reuse cached results, and rebuilds keep running while the tab is in the background instead of stalling
• Leaner files — temporary snapping data is no longer written into saved files, undo steps or autosaves, and files that already contain it drop it when reopened

• Imports can become editable features — STEP, STL and 3MF imports now offer Keep solid, Hybrid features (the new default) or Native features, rebuilding holes, pockets and bosses as real features wherever they match
• Watch it rebuild, keep what matches — a live panel shows how closely the rebuilt features match the original (anything under 99.5% stays unticked), and you finish with Keep or Restore original
• Correctly sized STLs — the STL dialog asks what units the file uses and shows the resulting size, flat areas come in as sketchable faces, and very dense STLs that used to time out now import
• SCAD Customizer upgrades — Add as solid body now takes dense models with Exact or Simplified detail on a much faster OpenSCAD engine, each parameter shows the faces it drives, and an Advanced editor lets you tweak the code
• SCAD to features — the experimental Try converting to features turns OpenSCAD code into sketches, extrudes, revolves and patterns, keeping anything it can’t recognize as an exact solid
• STL exports slicers accept — large, finely exported parts no longer lose tiny triangles, so slicers stop asking to repair the file

• Trace Wizard — paste, drop or browse a picture and turn it into the fewest lines, arcs and splines: lasso the part you want, auto-trace or trace by hand, tidy it up and place it at a set size
• Drop an image, choose what it becomes — dropping a picture, SVG or DXF asks whether to trace it into a sketch, make a 3D logo or use it as a backdrop, and placed outlines snap to the face’s centre lines
• Copy & paste sketches — right-click a sketch to copy it, then paste it onto any face, duplicate it on the same plane or paste it into the open sketch (Ctrl+C / Ctrl+V work too)
• Close Profile & Extend — Close Profile finds every open end and extends, trims or caps it into closed regions with a live preview, and the new Extend tool grows a line or arc to the next entity
• Offset that remembers and follows — Offset keeps your last settings, takes several clicks or a box selection, and follows its source, so editing the original keeps the wall thickness
• Face Sketch — copy a flat face’s exact outline (holes included), or a section through any body, into a new editable sketch

• Chamfer sizes per edge — each edge in a chamfer can have its own size, Fit and Fit all give edges the largest chamfer they can take, and the slider previews live
• Fillet Max you can trust — Max and the size chips now measure the real room along the whole edge on both faces, and a fillet that rounds only some of its edges warns instead of showing green
• Thread caliper wizard — “Measure a thread with calipers…” walks you through the readings with caliper drawings, then ranks the matching machine and bottle/jar threads
• Pattern upgrades — Linear Pattern’s second direction defaults to a sensible in-plane direction with Flip and Pick buttons, Fit leaves equal margins, and Circular Pattern can keep every copy facing the same way
• Move Body “Up to…” — bring a picked face or corner of a body up to a face, vertex or point on another body, with an optional gap
• Up To Surface lands exactly — extrudes and cuts to a curved face stop right on that surface, and cuts no longer bite into the face they stop at

• Always-visible rollback bar — drag the bar up to go back in time, add or edit features there, then drag it back down to rebuild the rest
• Reorder history by dragging — dragging a feature in the tree shows a snapping insertion line, and moves that would break a feature are refused
• Undo that covers everything — 30+ more actions now undo properly (text properties, colours, Hide/Show Body, unit switches and more), and Cmd+Z and Ctrl/Cmd+Shift+Z work too
• Rebuild only what changed — edits rebuild from the first changed feature instead of the whole tree (one chamfer edit went from ~1.8 s to ~0.2 s), and Esc cancels a long rebuild
• Faster heavy parts — follow-up fillets skip hopeless retries (one part went from 21.5 s to 6 s), separate bodies build in parallel, and scrolling the tree no longer freezes on big imports
• Modeling fixes — Shell on a multi-body part hollows only the body you picked, threads in blind holes render correctly, and chains of assembly mates stay attached

• No more 45° lock — lines, arcs and slots still snap to horizontal and vertical but no longer lock onto 45° diagonals, so angled lines go exactly where you draw them
• Draw on thin faces — on a narrow face the long edges only grab the cursor after you rest on them for about a second, while corners and midpoints still snap instantly
• Round sizes from the first click — a first click in empty space snaps to the dimension grid (hold Ctrl for a free point), with separate steps remembered for mm and inch documents
• Dimensions that don’t block you — a dimension that would over-define the sketch is kept as a grey reference dimension instead of a blocking pop-up, and arc caps no longer leave a sketch stuck Over Defined
• Better arcs — sketch Fillet now rounds line–arc and arc–arc corners, and relation badges can be dragged out of the way
• Pick the region you mean — where lines, circles or splines cross, each enclosed piece is its own region in Extrude/Cut, and thin-walled sketches no longer collapse into a slab after a dimension edit

• Redesigned Extrude/Cut pane — a compact pane with illustrated choices and profile thumbnails that highlight on the part, a Reverse for each direction, and depths that survive switching end conditions
• Calmer previews, draggable arrows — feature previews default to translucent grey with white edges (cuts stay red), Settings adds colour presets, and Extrude/Cut arrows can be dragged to set depth
• Ctrl+K command search — find any command by name or synonym (“round” finds Fillet, “hollow” finds Shell), and it opens the right ribbon tab so you learn where the tool lives
• Searchable Settings — a search box jumps to any option, a new Viewport section toggles axes, origin planes and grid, and changes apply as you edit
• Arrow keys rotate the view — plain arrow keys turn the model 45° per press, just like the on-screen rotate arrows
• Better thumbnails — gallery cards use full-width art framed to each part, and Open Drive reads every preview straight from the file

• Translated end to end — Spanish, French, German, Portuguese, Chinese and Japanese now cover ribbon tooltips, every feature dialog, sketch prompts, assemblies, drawings and wizards (about 4,350 phrases, up from 640)
• Academy and website translated — all 458 Academy lesson texts are translated as whole sentences, and the feature and comparison pages follow your in-app language
• New lessons & the Workshop Rover — new Edit, Undo & Save and Make a Through Hole lessons, plus a 3D Workshop Rover on the Academy home whose parts colour in as you finish lessons
• Friendlier scoring — hints no longer cost stars, replays keep your best result, and on-model highlights point at the exact geometry each step means

• Cancel Subscription fixed — the button now reliably cancels your plan, including on older accounts, confirms with the payment provider that billing has stopped, and shows a clear message if anything goes wrong
• Cancelling checks your sign-in — the request is tied to your signed-in account, and if your sign-in has expired you’re asked to log in again instead of hitting a dead end

• Big assemblies load again — the Grand Clockwork example no longer hangs on “Building assembly…”; parts build side by side in the background as intended, about 3× faster than one at a time
• Solid section caps on painted parts — Section View on a part with coloured faces shows a solid, shaded cut again instead of a see-through, washed-out slice

• Fillet & Chamfer selection list — the panel opens the moment you click the tool, every picked edge, chain or face gets its own removable row, and edges hidden behind the part can’t be picked by accident
• Round edges fillet properly — a cylinder rim counts as one edge with a suggested radius, curved edges always preview, and Full Round now gives an exact half-wall radius
• Break-out fillets at full size — filleting the floor of a round pocket that runs out through a side wall now builds at the radius you typed, with a smooth run-out and no sliver spikes
• SolidWorks-style Sweep — click a closed shape for the profile and an open curve for the path, watch a live preview, and use the new Path Length setting (75% or 30 mm) to sweep part of the way
• Mirror a single feature — Features to Mirror copies just the extrude or cut you choose instead of the whole body, with a ghost preview and a Pick Plane button for midplanes, offset and angled planes
• Patterns repeat your last feature — Linear and Circular Pattern copy the last extrude or cut by default (Full Part is a separate choice), spacing scales to your part, and copies of hollow shapes stay hollow
• Click regions on the model — in Extrude/Cut, click a region in the viewport to add or remove it; Through All in Direction 2 now cuts all the way and Mid Plane uses the full depth you type

• Auto-dimensions land where you saw them — the dimension added after drawing a rectangle, circle, polygon, line or slot appears exactly where the live readout was, and horizontal/vertical point dimensions no longer show the diagonal
• Trim keeps your dimensions — trimming a dimensioned line, circle or arc moves its dimensions and relations onto the surviving pieces instead of quietly deleting them
• Editable sketch fillets — a 2D sketch fillet gets its own radius dimension you can change later in Properties, and typing a new radius updates the fillets you just placed
• Arc tool finishes cleanly — completing an arc ends the tool and adds a radius dimension right where the live readout was
• Text that fits and grabs — new text sizes itself to the profile you’ve drawn (it used to be a fixed 10 units, which meant 10 inches in an inch file), you can drag it by any letter, and every letter extrudes as a clean solid
• Top-bar toggles for dims & icons — two new buttons switch auto-dimensioning and constraint icons on or off; icons are 10% smaller, hug their own edges and never cover dimensions
• Tidier dimensions — diameter and radius leaders stay put while you drag, and cramped linear dimensions move their arrows outside

• Sketch right on round surfaces — in a 3D Sketch, starting a shape on a cylinder or cone wall places a Tangent to Wall plane there, with an orange contact line you can drag around and along the wall
• A clickable, snappable origin — click the sketch origin to use it in Coincident or Concentric; it highlights on hover, shows a snap halo, stays visible at any zoom, and V zooms to it in an empty sketch
• Clicks land where you aim — a short line lying on a longer one can now be picked, relation badges no longer swallow clicks in Fillet, Trim, Offset and Mirror, and drags leave no stray dashed guides
• Sketches open facing you — a sketch reopens from the side you drew it on and is never shown through the part; pressing V when you’re already square-on flips to the other side
• 3D sketch dimensions that drive — point-to-point dimensions in a 3D Sketch now move the geometry, and a typed 135° angle stays 135° instead of becoming 45°
• Auto-Define finishes the job — Auto-Define no longer stalls on a finished shape drawn away from the origin

• Imports no longer freeze the page — big STL and 3MF conversions now truly run in the background, multi-part files build up to 4 parts at once, and one stubborn part can’t hang the tab
• Threads in STLs become real threads — modelled threads in an imported mesh are recognized, snapped to a standard size such as M3×0.5 and rebuilt as an editable Thread feature
• Fast or exact, your call — the new “Simplify dense mesh” option (on by default above 10,000 triangles) makes big imports much faster while keeping threads exact and one-piece parts in one piece
• Import progress you can read — the import panel shows each step with a plain-English note, a progress bar and a running clock
• Build onto imported bodies — a boss sketched on a face of an imported mesh now merges into it as one solid, and threads added to imported nuts stay clean and export watertight
• Laser-ready layer numbers — Slice Sheets and SVG Layer Art engrave layer numbers as vector lines your laser software actually shows, placed on the part, with position and size options

• Save to Google Drive — opt-in Save to Drive and Open Drive keep your designs in a BasicCAD folder in your own Drive (BasicCAD only sees files it created), with optional auto-sync of every save
• Report a Bug button — a bug button in the top bar sends your current file and a session recording with your note, after explaining exactly what’s shared
• Cloud Sync for subscribers — your preferences, ribbon layout, keybindings, saved threads and Academy progress follow you to every device you sign in on
• Your sketch stays in view — Exit Sketch keeps the sketch on screen until a feature uses it, hovering a sketch in the Design Tree previews it on the model, and feature dialogs dock on the right
• Errors that explain themselves — features that fail to rebuild are named in the status bar with the reason, such as “radius too large for the selected edge(s)”
• Home & display polish — clicking the logo always returns cleanly to the start screen with your work saved to Load Recent, section view paints each body’s cut in its own colour, and small fillets shade smoothly

• Perfect-mug lessons — the Mug Project lessons now lock the handle with dimensions and finish with fillets where it meets the cup, plus a rounded rim and base
• Highlights never point at nothing — when the button a step needs is hidden on another tab, in a collapsed group or in a dropdown, the gold highlight shows what to open first
• Smoother lesson flow — the next lesson opens in a clean workspace without reloading, Skip lesson returns to the Academy, and lessons build upright like their pictures
• Lessons work in inches — the mug steps show inch values next to millimetres and check against the circle you actually drew

• Define Assistant — every 2D sketch gets a corner chip reading “Fully Defined”, “3 DOF — What’s missing?” or “Over Defined”; click it for plain-language hints, one-click relation suggestions and safe removal of redundant relations
• One-click Auto-Define — applies the relations your sketch almost has, anchors it and adds the missing dimensions, test-solving every step so nothing jumps
• Pick the angle you mean — after picking two separate lines with Smart Dim, move into the angle you want and click to place it, with a live preview of the arc and its degrees
• Angles that match the picture — the typed value, the preview and the final arc always agree, typing 150 really opens to 150°, and repeated edits swing the line about a fixed point without drifting

• Drags that keep up — constrained sketch geometry now follows the cursor exactly, and a blocked drag stops at the last valid position with a hint naming what’s locking it, instead of turning the sketch red
• Trim ellipses and splines — trim an ellipse’s bulge or a spline’s tail where it crosses other geometry (it used to refuse), with a hover preview that matches the result
• Trim hits what you click — trimming a circle removes exactly the piece you clicked, clicks within about 15 px count, and no invisible slivers are left behind
• Relations and drags get along — with a relation button armed, press-and-move still drags while a click applies the relation, and an over-defined (red) sketch can be dragged freely to untangle it
• Sketches can’t jam themselves — a circle’s centre can no longer get attached to its own rim, which silently froze every constraint in the sketch; affected files repair themselves on open
• Snaps land where you aim — when a line held at 0/45/90° can’t reach the edge you’re aiming at, the edge wins and the endpoint stays attached, and the origin now snaps in large sketches too

• Patterning a cut makes more cuts — a Linear or Circular Pattern of a hole or pocket now repeats the cut instead of adding solid copies of the part, and it’s far faster (one test went from ~80 s to under 1 s)
• Circular Pattern axis from round edges — click a hole or boss rim, a round face or a flat circular face and its centreline becomes the axis, and the preview shows just the repeated feature
• Sweep joins the body — a profile swept onto an existing part (a mug handle, say) now merges into one solid instead of silently vanishing
• Extruded words in one colour — extruded text is one colour by default (tick “Different color per letter” for the rainbow look), and letters no longer vanish after undo/redo or in assemblies
• Smooth curved outlines — sketching on a face with free-form edges gives one smooth outline instead of ~20 straight segments, and offsetting a spline stays smooth
• Polygons resize cleanly — changing a polygon’s size no longer folds a corner inward, spins the shape or drifts its centre, and already-folded polygons fix themselves on open

• Two new Mug Project lessons — 3.8 “Mug Project: Sweep a Handle” builds the handle from 2D sketches and 3.9 “Mug Project: the 3D-Sketch Handle” draws it in a 3D sketch, with animated click diagrams, new badges and a build-notes pop-out
• Through Axis planes on round walls — in a 3D Sketch, Plane on Point can now put a plane through a cylinder’s axis so you can draw straight out from the wall (X switches to Tangent to Wall)
• Grand Clockwork example — a 22-part clock mechanism: a worm drives a gear train and a true 12:1 hour-hand drive; hit Spin Gears, or Explode to fan the parts out along the shaft like a watch ad
• Spin panel for gear trains — Spin Gears now opens a panel with a 0.5–60 RPM speed slider, direction buttons and a choice of driving gear, saved with the assembly
• Moving Assemblies guide — a new Lesson button opens an illustrated guide to gear trains, the Spin panel, clearances, collision checks and exploded views

• Smooth camera in busy sketches — entering a sketch full of dimensions no longer freezes the fly-in, and orbit and zoom stay smooth while labels wait for the view to settle
• Snappier hover and picking — moving the mouse over a busy sketch no longer lags up to a second per move, and dragging a dimension label responds about 25× faster
• Cleaner STL/3MF conversion — far more of an imported mesh becomes clean flat faces and true curves (fillets, slot ends, spheres), and 3MFs saved by Bambu Studio and OrcaSlicer now import
• Views that face the right way — starting a sketch on a face no longer swings the camera behind the part, text on an origin plane no longer reopens mirrored, and V fits the sketch to the window again
• Tools that clean up after themselves — starting a feature tool closes the previous one (Fillet then Chamfer used to do nothing), and Smart Dim and Trim no longer leave stray dashed guides
• Recognize panel retired — the unreliable Recognized Features pop-up no longer appears after imports; use Editable to turn an imported body into features

• Fusion-style relations — a Basic/Advanced palette you drag onto the sketch: horizontal, vertical, parallel, perpendicular, coincident, tangent, concentric, equal and symmetric, each with a badge you can click to delete
• Curvature-continuous (G2) arcs for smooth, matched transitions
• Points are first-class — a placed point glues to the edge or face under it, and snapping to the origin creates a real, deletable coincident-to-origin relation
• An always-visible sketch origin marker, with a top-bar toggle
• Auto driving-dimensions now always yield to a dimension you add by hand
• Rigid slots — held solid (equal + tangent) with proper arc / slot-cap quadrant dimensions; older slots heal themselves when you open the file
• New Academy lesson — Relations Roundup: learn Parallel, Perpendicular, one-click Horizontal/Vertical, Fix and G2 Curvature hands-on — and how to delete any relation badge

• Draw a corner flush onto an existing edge and it stays bound — rectangles, slots, lines, arcs and midlines no longer drift off the edge on the next solve
• Endpoints win over centre/midpoint magnets, so snapping no longer “jams to the centre”
• Snapping now works while you drag, with a clear on-edge green dot; big circles and arcs are selectable right on their rim, and points on a curve are hoverable and pickable
• Angle-locked lines snap green to a crossing line or circle while holding 0/45/90° (Ctrl frees the angle); a line drawn across a corner no longer collapses straight
• One clean line-to-line dimension chooser (Distance / Angle) floated at the cursor, with correct angles at coincident corners and live preview while you type
• 3D sketch: a centred shape snapped onto an off-plane point lands on the point, not offset

• Much faster spline parts — a sketch spline is now a single smooth edge, so a traced-spline extrude that took ~20s builds in ~1.5s, and the app starts faster too
• More reliable rebuilds when you edit an upstream feature — fillets, chamfers, patterns, shells, holes and sketches-on-faces re-find their targets, and resizing a sketch no longer drags other face-attached sketches along
• Correct face picking — clicking a face selects the one you aimed at
• Long editing sessions stay lighter on memory
• Wrap engraving gets a cleaner outline edge (no stair-stepping)
• Several Academy lesson fixes and smoother snapping throughout

• Combine — merge, subtract or intersect separate bodies, with an optional clearance gap for press-fit and clearance-fit joints
• Deform — bend, taper, stretch or push/pull a finished solid into organic shapes
• Reference planes — build offset, angled, midplane and through-point datum planes, then sketch right on them
• Multi-body parts — one part can now hold several separate bodies, each with its own colour and clearer pick-highlighting
• Bevel gears added to the gear generator, with real 3D previews; gears can auto-mate and spin together in assemblies

• Math in dimensions — type 11 + .21*3 or 1-1/4 straight into a value box
• Named dimensions & variables — name a value like D8 = 20 and reuse it on other dimensions
• Dimension from the origin, and dimension to a circle’s quadrant (top/bottom/side) point
• Auto driving-dimensions — the size you draw is captured as a real dimension, with a live width×height / Ø readout that snaps to round numbers (toggle in Settings)
• Sticky Construction-Line mode + one-click Convert to Construction; endpoints automatically take the right relation when you snap them
• 3D sketches can loft across profiles on different planes, with rigid polygons and origin pinning
• The view auto-zooms out when a dimension grows the part past the window

• Fillet & chamfer now suggest a sensible size (half the neighbouring face) with one-click size chips
• Clearer live preview and smarter edge-picking that skips the wall hidden behind the edge you’re aiming at
• Fillets near holes or after cuts rebuild more reliably when you change an earlier feature
• Linear pattern gains “Fit” auto-spacing and an option to copy the seed body’s colour
• Edit any feature (shell, mirror, linear & circular patterns) through the same dialog you used to create it

• Hole Wizard v2 — counterbore & countersink, automatic fastener sizing, and interactive placement by clicking the model
• Thread library — a searchable picker for household/brand and standard threads that fills in size, pitch and form — plus a live “by eye” tuner and a saved-thread palette for matching mating threads
• Wrap Text/SVG — drag the artwork anywhere on a round face, with snapping
• Extrude cut now removes exactly what you drew — no more over-cutting past deliberate margins

• Auto Dimension — exact hole diameters, hole-location and slot/keyway callouts; running it again no longer piles on duplicate dimensions
• Mass Properties — material-driven weight, volume and area, with a table you can drop onto a drawing sheet
• Faster drawings — no more long freeze when switching or resizing sheets
• Assemblies — exploded views, collision/interference badges, gear trains that auto-mate and spin, and faster loading
• New example projects in the gallery (FPV drone, Fan Impeller and more)

• Slice to Sheets — export a model as stacked layers (DXF) for laser-cut or plywood builds, plus an SVG Layered Wood Art tool
• SpaceMouse — 6-DOF 3D-mouse navigation (WebHID)
• Properties panel — a new inline table to view and edit a feature’s key dimensions
• OpenSCAD import/customizer now renders in a background worker (no UI freeze), converting what it can to features and freezing the rest
• Arrow ↑/↓ steps any number field; no-change edits skip the rebuild; long rebuilds show a cancellable progress cube
• Smoother sketch orbiting and faster fillet edge-picking

• Line, rectangle, center rectangle, circle, arc, ellipse, polygon, spline and midline tools
• Editable text, including text that follows a curve for coins and badges
• Trim, offset, sketch fillet/chamfer, sketch patterns and construction geometry
• SVG, DXF and image import: raster pictures are traced into editable sketch shapes
• Constraints: horizontal, vertical, parallel, perpendicular, coincident, tangent, concentric, equal, fixed
• Smart dimensions: lengths, point/edge distances, radius, diameter and angles, with live snapping while you draw
• Global variables and equations that drive dimensions and feature parameters
• 3D sketches drawn directly on model faces, edges, points or floating planes

• Extrude boss and cut, with draft, thin walls, both-sides and start conditions
• Revolve, sweep along any 3D path, and loft between profiles
• Fillet, chamfer, shell, mirror, linear and circular patterns
• Real printable threads in ANSI and metric sizes, with print clearance and flat crests for FDM
• Involute gear generator: spur, helical and herringbone
• Helix curves, wrap (engrave or emboss on round faces) and twist
• Move/copy body, reference planes and plane-on-point
• Full feature tree: edit, reorder, suppress and roll back; downstream features re-attach when you change something upstream

• Per-face paint and section coloring on the model
• Multi-color 3MF export that slicers like Bambu, Orca and Prusa read directly
• STL and STEP export (STEP keeps your colors); STEP, STL, 3MF and OpenSCAD import
• OpenSCAD export for the MakerWorld parametric customizer
• Saved .cadjson files embed a built-in guide so AI assistants can read and edit your parts

• Assemblies with smart mates: concentric, planar, distance and more
• 2D engineering drawings: orthographic views, dimensions and title blocks
• Measure tools, section view and X-ray display modes
• Macro recorder and player for repeatable modeling steps
• Autosave with visual Load Recent history; installs as an offline app (PWA)

Why WebAssembly everywhere? Because it lets the entire CAD kernel run inside your browser. Nothing gets uploaded, the app works offline, and your designs never leave your computer.
