This question may be more generalized toward conversion types but SWX is where I want the data to end up.
I have a MDT assembly I want "quickly" converted into SWX to use in a design (not my idea to use 2 softwares on a single design

). I'd like to just convert it into a SWX part file to keep things clean. I saw it done a couple years ago where somebody converted an assy into a SWX part file that was just an accumulation of surfaces. This would be fine.
I tried the MDT > IV > IV derived part > STEP > SWX. Problem #1 is that it's a long process (and I'll probably have to do this a few more times in the future). Problem #2 was that SWX crashed when I hit the Save button
So, does someone have a suggested neutral file format and format settings that would work. I tried ACIS, STEP, & IGES but all came in as assemblies. I was hoping I could choose a setting within one of these formats that would just combine the entire assy model into a single part when converted.
Also, for you SWX users more experienced than I, remind me what SWX's calls their version of Derived Component. I can't remember.
Thanks.
