What the maker publishes

2D drawings
It can export 2D parts as DXF, PDF, and SVG, and use 3D assembly to verify fit. source
3D modeling
It creates 3D parts with extrudes, revolves, helixes, and Boolean operations. source
3D printing and CAM
It exports STL or other triangle meshes for 3D printers, and exports vector art or STEP/STL for CAM software. source
Assemblies
Parts can be linked into parametric associative assemblies, where changes to parts propagate automatically. source
Browser availability and limits
An experimental browser version is available, but the maker says it has a speed penalty, remaining bugs, and issues not found in desktop targets. source
Constraints
It supports geometric constraints and dimensions in 2D projections and 3D, with metric or inch units and arithmetic expressions. source
Exports
Export formats include DXF, EPS, PDF, SVG, HPGL, STEP, G code, STL, and Wavefront OBJ. source
Free plan
Yes source
Integrations
The site describes exporting files for third-party CAM software and use of 3Dconnexion six-degree-of-freedom controllers. source
Library licensing limit
The constraint-solver library is available with source, but GPLv3 generally forbids linking it with proprietary software; commercial licensing inquiries are invited. source
Mechanism design
Its constraint solver can simulate planar or spatial linkages with pin, ball, or slide joints. source
Offline/self-host option
The web version has no network dependencies after loading, and the maker says users can build and host their own copy as static web content. source
Parametric modeling
Yes source
Platform access
both source
3D print export
Yes source
Render engine
built-in source
Sketching
Sketch entities include lines, circles, arcs, Bezier segments, interpolating splines, and TrueType text. source
Support
The maker directs questions to its user forum and bug reports or feature requests to its issue tracker. source
