Design in 3D, right in your browser.
Precise parametric CAD, in your browser. A constraint sketcher, a parametric journal and your own documents — with nothing to download. Solid modelling is unavailable until an approved geometry kernel is qualified.

§01 — PRODUCT
Parametric CAD documents in the browser, without an install.
Sketching, parameters and the document journal run on your machine, in the tab you already have open. Solid modelling is unavailable in this build: no geometry kernel is qualified, and nothing is approximated in its place.
Parametric history
Every operation stays editable and the journal keeps them in order. Replaying one into geometry needs a kernel, so in this build the history is authored and stored, not rebuilt.
No approved geometry kernel — exact modelling unavailable until a kernel is qualified
Constraint sketcher
Draw profiles and let a real solver hold them. Coincident, tangent, parallel, equal, dimensional — fully constrained or as loose as you like. The solver is first-party and needs no kernel.
Assemblies and mates
Structure, occurrences and the mate solver are first-party and run here. The solids they position come from a kernel, so this build assembles metadata rather than geometry.
No approved geometry kernel — exact modelling unavailable until a kernel is qualified
Technical drawings
Projected views with real hidden-line removal, section cuts with hatching, isometrics, and dimensions that come from the model. Every one of those is derived from exact geometry.
No approved geometry kernel — exact modelling unavailable until a kernel is qualified
Standard parts library
Parametric bolts, nuts, washers and screws with real threads, plus tube, channel, angle and I-beam sections for weldments. The catalogue is data; turning an entry into a solid is a kernel operation.
No approved geometry kernel — exact modelling unavailable until a kernel is qualified
Exports that open elsewhere
CSV bills of materials and cut lists export today. STEP, STL and OBJ are written from geometry, so they wait on a qualified kernel rather than shipping an approximation.

§02 — WORKSPACE
A modelling environment, not a viewer.
Section planes, exploded views, mass properties and true face-to-face measurement — the inspection tools sit next to the modelling tools, not behind a paywall.

§03 — PLATFORM
A CAD stack, running in one browser tab.
One history for every part.
Sketches, pads, fillets and patterns stay editable end to end — change a dimension upstream and the rest of the tree rebuilds around it.
Sheets that stay in syncwith the model.
Projected views, section cuts and dimensions come straight from the solid, and the bill of materials updates the moment a part count changes.
Share a link, not a file.
Projects live on the server, not on one machine — open the same assembly from any browser and pick up exactly where you left off.
§04 — PROOF
Four claims worth making, and enough detail to check them.
No geometry kernel is qualified
Solid modelling, measurement and 3D export are unavailable in this build. Each one answers with a stated refusal rather than an approximation, a placeholder solid or a zero.
Sketching and constraints work today
The 2D constraint solver, named parameters and expression evaluation need no geometry provider and run in your browser, on your machine.
Documents are journals, not black boxes
A document is an ordered, readable record of parameterised operations. It can be opened, inspected, diffed, merged and versioned with no geometry engine present.
Nothing here is a mock
Where a capability is unavailable it is listed as unavailable. No fabricated mass, area, volume or clearance value is produced anywhere in the product.
§05 — SPECIFICATIONS
Everything that is actually built, on one sheet.
- Geometry
- Unavailable: no approved geometry kernel is qualified for this build
- Solid modelling
- Unavailable — every geometry command answers with a stated refusal
- Measurement and 3D export
- Unavailable for the same reason; no approximate value is returned
- Sketching
- Constraint solver: coincident, tangent, parallel, equal, dimensional
- Documents
- Parametric feature journal — open, inspect, diff, merge, version
- Parameters
- Named parameters and algebraic expressions, with cycle detection
- Collaboration
- Presence, offline autosave queue, three-way document merge
- Execution
- Everything above runs in your browser, on your machine
- Install
- None. It is a browser tab.
§06 — WHO IT'S FOR
Built for people with an idea and a machine that can’t.
Mechanical engineers
Parametric documents, named parameters and a constraint sketcher, without a licence server. Solid modelling waits on an approved geometry kernel.
Product designers
Iterate on form with a constraint sketcher and an editable, readable history that travels as plain document data.
Makers and fabricators
Sheet-metal, weldment and fastener definitions live in the document today; producing solids and meshes from them waits on an approved geometry kernel.
Free to use, and free to leave
There is no paid tier to be moved onto later, because there is no billing here at all. What follows is what that means in practice.
Start modeling — free, no install- No geometry kernel, stated plainly.This build has no approved geometry kernel, so solid modelling, measurement and 3D export are unavailable and say so. Nothing is faked while you wait.
- Free, with nothing to clear first.No card, no install, no waiting on someone to approve a licence. Sign in and start modelling in the tab you already have open.
- Your work leaves with you.Your documents are readable, exportable data you can take elsewhere. Nothing here is designed around you being unable to leave.
