Is there a preferred method to dealing with large STP files? I have some that are 200-800mb a piece (truck frames, suspension, etc) and it takes from 20 minutes to a couple hours to even open these files. Is there a way to have them opened purely as a reference? I dont want to do any type of modification to these files, I just want to use them to build off of. I've opened a few and saved them as sw assemblies but the load times on those are still pretty crazy and the performance is pretty bad as well. Maybe use another program to convert them or pull apart these assemblies into what I need? I saw mention of using Fusion 360 to do this but it won't open any of the files.
