Informazioni sullo strumento
STL files contain raw triangle meshes without CAD intelligence — no parametric features, no analytic surfaces, no tolerances. This converter performs surface reconstruction to generate STEP files with approximate NURBS surfaces, enabling editing in CAD software like SolidWorks, Fusion 360, and FreeCAD.

Domande frequenti
How accurate is the STL to STEP conversion?
The conversion performs surface fitting on the triangle mesh to approximate NURBS surfaces. Accuracy depends on the mesh quality and complexity of the original geometry. Simple mechanical parts convert with high precision, while organic or highly detailed meshes produce approximate surfaces.
Can I edit the resulting STEP file in CAD software?
Yes. The output STEP file is a standard B-rep solid that can be opened and edited in most CAD applications including SolidWorks, Fusion 360, CATIA, and FreeCAD. Note that parametric history from the original design is not recoverable from mesh data.
Can I edit the converted STEP file in SolidWorks?
The output STEP file can be opened and basic edits can be made in SolidWorks. However, since it's a reconstructed surface model, it does not contain the original parametric design history (extrusions, revolves, etc.), so editing capabilities are limited.
How well does organic shape (e.g., body scan) conversion work?
Surface reconstruction for organic shapes is more challenging. Complex biological forms (faces, bodies) may not perfectly fit into CAD surfaces. Mechanical parts and regular geometry convert much better than organic shapes.
Can the STEP file be used for CNC machining?
Yes. The STEP file contains standard B-rep solid data that CAM software (e.g., Fusion 360 CAM, Mastercam) can read to generate CNC toolpaths. Verify surface quality before using for precision machining.
How does STL face count affect conversion quality?
More faces mean the mesh more closely approximates the true surface, resulting in higher-accuracy surface fitting. Low-face-count STLs (under 1,000 faces) may produce rough results. We recommend using STLs with at least 10,000 faces for good reconstruction.
