Import CAD data from IGES and STEP files directly into Blender as mesh or curve objects. The add-on converts NURBS surfaces to meshes, BREP objects to mesh objects, and NURBS curves to POLY curves. Users can control the meshing process with tolerance and sharpness parameters to balance mesh density and conversion time. An option to sew surfaces into shells before mesh processing is included, which is useful for IGES files to prevent gaps. Importing curves creates a dedicated collection for the imported POLY curves.
