FreeCAD STL-to-STEP conversion and limitations
Converting an STL to STEP can create a usable exchange file, but it does not recreate a clean parametric model. The public workflow emphasizes mesh cleanup, scale checks, reference geometry, and remodeling critical features.

A CLOSER LOOK
A converted mesh keeps its history missing

TECHNICAL NOTES///
FreeCAD mesh-to-solid workflow with an explicit warning about lost design intent.
PUBLIC KNOWLEDGE VIEWCAD / Scanning / Automation / how-to
GOALRecover usable geometry without mistaking a converted mesh for a native design.
EQUIPMENT
- FreeCAD
- Representative test model
- Measurement or inspection method
STEPS
- Inspect and repair the mesh.
- Confirm scale with a known dimension.
- Convert only when the downstream tool requires it.
- Remodel critical features with clean sketches and constraints.
- Export and inspect the result.
TROUBLESHOOTING
- A visually correct model can still have bad units, references, or manufacturing intent.
- Keep source files and exported files distinct.
- When automation is involved, test a copy before changing a production directory.
RESULTReference workflow with known limitations.
