Buerligons is a parametric, history-based CAD modeler that runs entirely in your browser: the ClassCAD engine, compiled to WebAssembly, working in this very tab. Nothing to install, no server doing the modeling.

Drag the red bar: the part rolls back

01Sketch

Constrain a profile, then give its dimensions names. A name can drive another, and changing one reshapes everything built from it, the solid included.

Buerligons · Mittelrolle · Sketch
The Buerligons sketcher: a roller profile with named, constrained dimensions such as @Breite and @Traegerbreite
Buerligons · Assembly
A Buerligons assembly: the roller fastened into its frame, with the constraints listed under the tree

02Assemble

Put parts together with 3D constraints, give a joint its limits, and drag it: the assembly moves the way the real thing would.
