SLDPRT File Converter
We can't convert SolidWorks Part (SLDPRT) files — here's what does work.
Why SLDPRT can't be converted here
SLDPRT is SolidWorks's own closed format. Its internal structure is proprietary, so no open-source library can read it — which is why no converter outside SolidWorks can open your file.
What does work: open the file in SolidWorks and export it as STEP. We convert STEP reliably.
