Export STL as a Faceted STEP Model
This route wraps triangle geometry in a STEP-compatible faceted model. It is useful for exchanging a mesh with CAD systems that accept STEP containers.

What to check before you export
The result is not a parametric solid with editable sketches or feature history. Preserve the original STL and verify the faceted surface in your CAD application.
Use the export when a CAD handoff accepts STEP more readily than STL. The faces remain planar triangles, so treat the file as a reference shell and rebuild critical dimensions or manufacturing features in CAD.
Frequently Asked Questions
Is the output a parametric CAD solid?
No. It is a faceted STEP representation of the triangle mesh, without editable sketches, features, or design history.
Why use STEP for an STL mesh?
Some CAD pipelines accept STEP more readily than STL. The export changes the container but does not reconstruct design intent.
Should I repair the STL first?
Yes. Review open edges and non-manifold topology before exporting to another engineering workflow.
