Inspection focus
Repair reports for accountable workflows
This page focuses on evidence: what was repaired, what was skipped, and what can be exported.
- Use before/after score and issue deltas to review changes.
- Keep report-only items visible for customer or internal notes.
- Create server repair artifacts only after local preview is understood.
Repair boundary
Report-first export boundary
Downloads should only happen after the server verifies ownership, file state, and plan entitlement.
Supported
- Safe repair preview
- Server repair artifact creation
- JSON report export for Pro users
Report only
- Manual CAD edits
- Guaranteed customer acceptance
- Hidden changes without action log
FAQ
Questions before the next print
What is included in an STL repair report?
The report includes score, issue counts, severity, repairability, before/after deltas, and action log entries.
Why show skipped repairs?
Skipped repairs make the boundary honest. They explain geometry that the current engine should not edit automatically.
When do I need a paid export?
Use paid export when you need a private server-created repaired STL or JSON report after reviewing the local preview.
