FAQ
What counts as a feature?
Each CAD operation in your part: sketches, extrusions, fillets, chamfers, patterns, holes, shells, and reference geometry. System features are excluded.
What file formats are supported?
Siemens NX .prt files as input. SolidWorks .sldprt files as output.
How long does conversion take?
Converted files are typically available within 1–5 minutes. If flagged for agent review, results will be available within 48 hours.
Can I use the API programmatically?
Yes. Generate an API key from your console and use our REST API. See the documentation for details.
