Libraries and sample code we publish on GitHub. Issues and pull requests are welcome.
Bas-Automation-Services on GitHubReusable code you can build on.
Dependency-free 2D/3D computational geometry for .NET: points, vectors, matrices, planes, lines, arcs, circles, ellipses, coordinate systems, swept surfaces and ray casting. The managed geometry behind our Inventor add-ins.
An implicit (F-rep) CAD kernel in C#: exact distance fields, certified queries, face names that persist through edits, exact STEP export, a WebAssembly playground and an MCP server. A research project into whether an implicit core can keep stable references to faces, edges and vertices.
The runnable code behind our Autodesk Inventor blog series.
Runnable code for the transient-beam series: building bodies with TransientBRep and TransientGeometry, and showing them with client graphics.
Code for the Inside Frame Generator series: an Inventor add-in that places an endplate on a Frame Generator beam and re-resolves its constraints when the beam profile changes, plus the classes for reading the skeleton data.
