RapidDraft synthetic FreeCAD prompt¶

    Candidate: Lamella pusher head side plate
    Pilot: SOMIC
    Revision: REV A
    Material: Al 7075-T6

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

    Base geometry:
    Large machined side plate with guide-hole pattern, bearing seat, and lightweight pockets.

    Key features:
    - guide-hole pattern

bearing seat
lightweight pockets
tapped mounting holes
assembly-reference edge
```
Critical dimensions:
- 320 x 180 x 12 mm
```
- Guide-hole grid about 160 x 80 mm
- Large bearing seat
  
  Revision intent: Generate the baseline release candidate without the documented follow-up change.
  
  Documented Rev B delta: - Move one guide hole by 0.8 mm to correct alignment. - Add one extra weight-reduction pocket without changing the outer plate envelope. - Preserve the main bearing seat so the revision reads as a trimmed adjustment rather than a new plate.
  
  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.
