Manufacturing-ready CAD output

[mohdibntarek]

Description

Add support for exporting optimized designs as manufacturing-ready CAD files, including clean B-rep geometry, proper tolerances, and format support for downstream CAM processes.

Context

Available in nTop, Inspire, Fusion, and Creo. This closes the loop from optimization to production — without it, the result requires manual reconstruction before manufacturing.

Scope

• STEP and Parasolid export
• Surface quality control (curvature continuity, minimum radius)
• Feature preservation (holes, threads, mating surfaces)
• Tolerance annotation
