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 and DXF at 1:1 mm for laser cutters and
2.5D CNC; it imports STEP, IGES, BREP, STL, SVG and DXF, and exports STEP,
STL, IGES, BREP, glTF, OBJ, 3MF, SVG and DXF. Real B-rep solids on the
OpenCASCADE kernel.
