How to convert SLDPRT to STP
- Add your .SLDPRT file - drop it in the box above or click to browse.
- Convert it to .STP in a few seconds.
- Download your new .STP file.
What to expect
- The solid transfers precisely as boundary-representation geometry, not as a faceted mesh.
- Parametric features and design history are dropped; the result is a static but accurate solid.
- STEP is not a mesh or print format, so 3D printing requires converting the result onward to STL.
Frequently asked questions
Does STEP preserve the solid model accurately?
Yes - STEP stores boundary-representation solid geometry with CAD precision, so the part transfers as an exact solid rather than an approximated mesh.
Why convert SLDPRT to STP?
STEP is the widely adopted ISO-standard neutral format for exchanging 3D parts and assemblies between different CAD programs, making it a reliable way to move a SOLIDWORKS part into another system.
What opens an STP file?
FreeCAD, CAD Assistant and the Autodesk Viewer open STEP free. The file is plain ASCII geometry.
What does not transfer to STEP?
The SOLIDWORKS feature tree, parametric dimensions and editable design intent are not preserved. STEP carries the final solid geometry, so the model arrives as a static solid rather than an editable feature-based part.
