BasicCAD loads its geometry engines into your browser. The math runs on your device. Local modeling doesn’t upload your designs to a BasicCAD file server.
Optional sharing and cloud connections are your choice.
ESTABLISHED OPEN-SOURCE FOUNDATIONS
Real math.
Proven geometry engines.
WebAssembly brings these engines into your browser.
Open CASCADE
Precise solid geometry. The kernel also used by FreeCAD.
PlaneGCS
FreeCAD’s sketch solver. Dimensions and constraints, solved as equations.
OpenSCAD
The real OpenSCAD engine for your SCAD files.
Manifold
Mesh geometry for combining and subtracting solids.
