We are attempting to create Pro/E models from imported data. A vendor created Pro/E models in Wildfire and we have 2001, so we cannot work with the models. I had the vendor send us STEP files, thinking we could import the models and re-create the models in 2001. After creating the first protrustion, we found the protusion would fill in the imported STEP data. Is there a workaround for this? What data format would be best to work with? Eg, IGS, NEU...
