RapidDraft synthetic FreeCAD prompt¶

    Candidate: Folding die block
    Pilot: SOMIC
    Revision: REV B
    Material: Tool steel 1.2379

    Generate a mechanically plausible, feature-rich FreeCAD part that looks like a realistic engineering demo asset instead of a generic primitive.

    Base geometry:
    Compact machined tool block with stepped datum faces, dowel holes, and threaded mounting pattern.

    Key features:
    - stepped top face

dowel holes
mounting hole pattern
datum pad
clearance relief pocket
```
Critical dimensions:
- 160 x 80 x 40 mm
```
- 2 x Ø10 dowels
- 4 x M8 mounting features
  
  Revision intent: Generate the changed follow-up revision and make the revision delta mechanically visible.
  
  Documented Rev B delta: - Move one locating dowel by 1.5 mm to correct erection squareness. - Update the top datum pad to reflect the corrected setup condition. - Keep the overall block size stable so the revision reads as a tooling correction.
  
  Realism rules: - Keep the geometry manufacturable and parametric-looking. - Preserve the overall part identity between revisions. - Make the revision change obvious enough for RapidDraft diff and release-review storytelling. - Export a single STEP-compatible solid or compound. - Avoid customer-specific IP and treat this as a synthetic review artifact.
  
  Output contract: - Write a standalone FreeCAD Python script. - The script must export the final STEP file to sys.argv[1]. - Keep the script headless-safe.
