gen_step_assembly

Regenerates explicit assembly STEP targets and their package-local viewer artifacts.

python <cad-skill>/scripts/gen_step_assembly path/to/assembly.py
python <cad-skill>/scripts/gen_step_assembly path/to/assembly.py --summary
python <cad-skill>/scripts/gen_step_assembly path/to/imported-assembly.step --glb-tolerance 1.0

Targets must be explicit file paths:

• generated Python assembly sources
• direct STEP/STP files

Relative targets resolve from the current working directory; path/to/assembly.py works only when that path exists from the current directory.

Generated Python assembly sources must expose gen_step() returning an envelope with either flat instances or recursive children, plus step_output; see references/generator-contract.md.

Direct STEP/STP targets may use:

• mesh tolerance flags
• --color
• STL flags

--skip-topology is rejected for assemblies.

This tool does not generate directories and does not run gen_dxf() or gen_urdf().
