STL to STEP Converter

CAD programs work with STEP solids, not STL triangle meshes. This converter wraps the mesh as a STEP file your CAD software can import, so you can position, measure and reference it in an assembly.

Why convert STL to STEP?

• Bring a downloaded STL into SolidWorks, Fusion 360, Onshape or FreeCAD
• Use a scanned part as a reference in a CAD assembly
• Send a STEP file to a supplier who requires it

What to know

• The result is a faceted solid made of the original triangles, not a parametric model with editable features.
• STEP output is a Pro feature. The 24-hour pass unlocks it with a single payment.

How to convert STL to STEP

1. Select your .stl file above.
