# Shared CAD Library

`5-Applications/scripts/common` contains shared library code for CAD source discovery, generator envelope metadata parsing, STEP render artifacts, assembly flattening, STEP scene/selector extraction, STL/GLB/DXF helpers, and validation helpers.

It is not a generator command. Use `5-Applications/scripts/gen_step_part`, `5-Applications/scripts/gen_step_assembly`, `5-Applications/scripts/gen_dxf`, or the URDF skill's `5-Applications/scripts/gen_urdf` for generation.
