about

nx_step_geom.nx -- REAL GEOMETRY extraction from a STEP file (cadtwin P3a: structure -> actual coordinates). nx_step_parse gave the assembly tree/BOM; this pulls the model's real 3D geometry: parse every CARTESIAN_POINT entity's coordinate tuple (STEP reals like -10., 0.E+000, 2.5) into a fixed-point point cloud (fx256). That cloud is real model geometry -- feeds the bounding box, and directly into nx_partid (shape descriptor needs only vertices). Composes nx_step_parse. First rung toward face tessellation (planar/B-spline = the next rungs). license_tier: ORIGINAL
