An open surface body (a box without a lid, 100 × 80 × 50 mm) whose floor lies on a B-spline surface
4,000 mm square, trimmed to the 100 × 80 mm floor. The body's bounding box is 100 × 80 × 50 mm;
its floor's underlying surface is 40 times wider.

  • File: untrimmed-surface-body.step
  • Author: raykholo
  • Made with: scripts/generators/untrimmed_surface_body.py (Python 3, standard library only).

Generated by the committed script in scripts/generators/ (writes AP214 directly) and regenerated byte for byte; the README has the expected counts, volume and bounding box. Checked against the generator's exact values in FreeCAD. Released under CC0-1.0; python3 scripts/check.py passes.

An open box, 100 x 80 x 50 mm, whose floor is trimmed from a B-spline surface
4,000 mm square: a bounding-box stress for readers. AP214, generated by
scripts/generators/untrimmed_surface_body.py; README gives check values.
