I was given a drawing (stp file) that was originally drawn in KeyCreator. I've been asked to convert it into a SolidWorks model and update some features.

When I open the file within SolidWorks, it comes in as a solid imported body. I run the import diagnostic, heal some minor faults, then attempt to run FeatureWorks and the Recognize Features option. It runs for probably 15 minutes, recognizes only a handful of features, and finally says "FeatureWorks could not process further".

I eventually abandoned ship and attempted to redraw the model from scratch, but the key feature of the model is too complex for my very limited experience with SolidWorks (less than a year with the software, mostly self taught).

Any ideas on how to recognize the features on the imported body so I can make changes to the geometry?

If needed, I can attach the file if someone would be willing to attempt it.

Much appreciated!!
