How to convert SLDPRT to IGS
- Add your .SLDPRT file - drop it in the box above or click to browse.
- Convert it to .IGS in a few seconds.
- Download your new .IGS file.
What to expect
- Geometry transfers with CAD precision as surfaces and wireframe, not as a tessellated mesh.
- Because IGES is surface-based, a solid may import as separate surfaces that require healing or stitching to become watertight.
- Parametric features, the feature tree and design history are lost; only the geometry moves across.
Frequently asked questions
Does IGES keep the precise geometry, unlike a mesh format?
Yes - IGES stores exact surfaces and wireframe rather than triangles, so the part's curves and faces are preserved with CAD precision.
Why convert SLDPRT to IGS?
IGES is a vendor-neutral standard for moving part geometry between different CAD programs, so it is a practical bridge out of SOLIDWORKS into another CAD system.
What opens an IGS file?
FreeCAD and Open Cascade CAD Assistant open IGES free, and the Autodesk Viewer shows it online. IGES is plain ASCII text.
Are there caveats with IGES surfaces?
IGES is surface- and wireframe-based, so a solid can arrive as a collection of surfaces that may need stitching into a watertight body, and the SOLIDWORKS feature tree is not carried over.
