What's new in WebCAD

October 10, 2026

Edit STL and OBJ files

• Cut into and add to an imported mesh. Sketch on an imported STL or OBJ, then Extrude Cut or Merge. A watertight mesh of up to 20,000 triangles becomes an exact solid on the first cut or addition. One Undo brings the mesh back, and Save, Open and STEP export keep the solid. A mesh it can't take (holes, flipped or crossing facets, or more triangles) is refused with the reason.
• Large meshes work in the background. The tab stays responsive while a cut runs, the panel says it is working, and Cancel stops it with nothing changed. Undo and Redo of a part made from a mesh are immediate.
• STL files import in seconds; a 50,000-triangle file used to take minutes.
• Export > STEP with a mesh in the scene says which parts are meshes and offers Export STL for them. Export STL writes every part where it is shown.

Drawings that dimension themselves (Pro)

• A sheet dimensions its part from the exact geometry, in ISO or ASME style: each size once, and callouts for holes (through, depth, counterbore, countersink), bolt circles, slots, radii and chamfers.
• Edit on the sheet: click a dimension to select it, drag to move it, double-click to retype it, Delete to remove it, and Ctrl+Z to step back.
• Standard paper with a zoned border, title block, notes and revisions. The front, top, right and isometric views show hidden hole walls and the projection symbol. Drawings are saved with the project and export as PDF, SVG or DXF.
• Ask CAD Genie for a part with dimensioned views and it builds the part, then opens the dimensioned sheet.
• Drawings print Japanese, Korean, Chinese and Arabic text.

Edit Feature

• Change a feature after it is built. Right-click an extrude, cut, merge, revolve, sweep or loft to reopen it in its panel. It rebuilds in place, along with everything made from it.

11 languages

• WebCAD now speaks French, German, Spanish, Italian, Brazilian Portuguese, Japanese, Korean, Simplified Chinese, Traditional Chinese and Arabic (right to left), as well as English. CAD Genie answers in your language.

Modeling

• Sketch cuts and bosses are exact: no thin lip is left behind, and stepped pockets are cut once.
• Sketch cuts and bosses across curved walls (ellipses and splines) build instead of being refused, and so does a hole inside a curved plate.
• Spline bosses and pockets on spline parts build, and curved parts draw cleanly.
• Fillets on slots, pockets, rebates and keyed shafts.
• A cut from a sketch plane that crosses the part cuts exactly the depth you type.
• Drawing a spline right after opening the app no longer crashes it.

Simulation

• Large stress studies finish in the browser: quadratic elements at the default mesh size, and linear elements up to the finest mesh. A mesh too large to solve says so and suggests a coarser one.
• Stress results show a colour bar over the model in MPa. Study setup is in one place and in order, typed forces point the way you mean, and loads spread by area.
• Heat studies follow the same ordered setup, and the result is drawn where the part is.
• A Vortices view in airflow studies shows where the flow swirls. Auto-sized wind tunnels run about twice as fast on a 4 GB graphics card.
• 2D airflow on your own part: run a quick study on a cross-section of a part you designed.

CAD Genie

• Reads much larger models before it changes them.
• A request that times out, or that CAD Genie can't answer, costs no credit.

Plans and fixes

• Heat, airflow and drawings show what Pro adds, with one Upgrade button, instead of the old access form.
• Dozens of everyday fixes from a full review of basic use, and every electronics board button either works or says why it can't.

September 25, 2026 release

Airfoils

• Import airfoil points. In a sketch, paste or load a coordinate file (.dat, .txt or .csv), set the chord length and position, and the section arrives as one smooth outline with its sharp trailing edge kept. Extrude it straight into a wing section.
• Airfoil polars. Lift, drag and pitching-moment curves for a section across a range of angles at the Reynolds number you choose, in a few seconds, with pressure and skin-friction plots, a table and CSV export. For the E387 section, NASA wind-tunnel measurements are drawn on the same plots. Open it from the CFD workbench (Pro).

Measure

• Measure tool in the toolbar. Pick faces, edges and points for lengths, radii, angles and distances, or two parts for the gap between them, in millimetres or inches.

CAD Genie

• Fixes its own first attempt. If a model it writes does not build, CAD Genie reads the reason, corrects the script once and rebuilds before replying, at no extra credit. The reply says what actually built.
• Wedges (tapered blocks, pointed fins, clock hands, ribs) now build.
• Size requirements are checked against the exact model rather than its on-screen mesh.
• Ask about an airflow study and CAD Genie answers from what is on your CFD panel: the settings, and the results once the flow settles. It can also run an airfoil polar from chat (Pro).

Airflow (CFD)

• A new default solver, checked against published drag data for spheres and cylinders. Results report average lift and drag, with their spread, once the flow settles.
• If a wind tunnel is too big for your graphics card, the panel says so before the run and gives the cell size that fits.
• Run details under each result list the Reynolds number applied, the steps run and the force samples taken.

Workspace

• Drag and drop a STEP, STL or OBJ file anywhere on the workspace to import it.
• The status bar shows the cursor position while you sketch and switches readouts between millimetres and inches.
• A quick-access menu in the header for theme, display mode and 4K capture.

Sign in

• Continue with Google. Sign in or create an account with your Google account in one click. If your Google address already belongs to a WebCAD account, you are signed into that account.
• Email confirmation and password reset links now open on WebCAD pages instead of a third-party address.

Sketching

• New relations: tangent, midpoint, collinear, symmetric and concentric, with over-constraint detection and defined-status coloring.
• New tools: mirror, trim, extend, offset, fillet, chamfer and patterns.
• Inference while drawing snaps to what you mean, and splines can be edited point by point.

ArchScript

• Spline profiles are a first-class sketch entity, closed or open.
• Tangency you can declare: arc ... tangentTo prev, tangent lines and radius blends produce smooth outlines without coordinate arithmetic.
• Ellipses in sketches.
• Swept tubes: pipe builds a bent tube from its 3D centerline with filleted bends. Stools, racks and frames are one body per tube.
• Gear trains: chained gear_mesh with one root crank, automatic tooth phasing, and driven ranges derived from the driver.
• Examples menu refreshed. 26 examples grouped by topic, every one verified on the native kernel, including eight taken directly from real design runs (brake pedal, wing rib, S-hook, shop stool, surfboard fin, egg cam, wiper linkage, pedal box).

Materials

• Assign a material from Properties. Select a body, pick steel, stainless, aluminium, copper, brass, titanium, plastics or FR4, and stress and heat studies pick up its properties automatically.
• Your own materials. Create one from scratch or customise a preset; they stay in your browser and can be edited or deleted later.

CAD Genie

• Deletes on request. "Remove the bracket" or "clear the scene" now works, and stress, heat and airflow studies can be started straight from chat on any existing body.
• When a generated model fails its checks, the chat explains each problem in one plain sentence instead of showing the raw report.

Drawings

• Real sheets. Create Drawing lays the views out on paper at one standard scale, third-angle, with a frame and title block, and the canvas shows the whole sheet.
• Holes and radii called out automatically. Each view marks its hole diameters and corner radii once, with TYP. where a size repeats.
• Manual dimensions. Length between two edges or corners, radius, diameter, and centerlines on any hole, with an undo. Tolerances still apply to any dimension.

Simulation

• Per-face mesh sizing for local refinement where the stress lives.
• Quadratic (tet10) elements for bending accuracy, and modal analysis with viewable, animated mode shapes.
• Validation receipts ship with the solver: cantilever bending within 1% of theory, modal frequencies within 0.05%.

Modeling and export

• WebCAD's own geometry kernel is now the default for both scripted and hand-built parts. The OCCT lane stays one click away for fillet preview and drawing views.
• One STEP button. Export routes to the right writer automatically, and stops rather than silently omitting a body from a mixed scene.
• Imported bodies get their own display shading so they read distinctly from native parts.

Performance and mobile

• Faster first load: simulation workbenches are fetched only when you open them.
• Inputs no longer trigger the zoom-in effect on iPhone.
