I have downloaded an SLDPRT file for the RSP1-T product from Newport Corporation.
I open it in SW 2017 SP0.0 and am prompted whether to do Feature Recognition or not.
If I say yes, the progress bar stalls out at ~10% Recognizing Chamfers and Fillets.
If I say no, I get a single "Imported Feature." I can mouseover the object and see various edges and faces highlight, but there is no parts tree that I can find. If I hide one thing, I hide everything.
Still finding my way around modern SolidWorks but shouldn't an SLDPRT file come up as a native part with the feature tree?
