Materializr is open-source 3D CAD for makers — the middle ground between
dead-simple tools like Tinkercad and full professional suites like FreeCAD.
Sketch on a plane, pull it into a solid (extrude, revolve, loft, sweep),
fillet and chamfer, run booleans, cut threads, and edit any step of the
history later. Sketches export to SVG at 1:1 mm for laser cutters and 2.5D
CNC; it imports STEP and IGES and exports STEP, STL, IGES, glTF and SVG. Real
B-rep solids on the OpenCASCADE kernel.
