I have three assemblies that I am working on that contain one big part and multiple subassemblies - one subassembly copied and mated differently to specific areas of the big part.
When I tried exporting each assembly as a STEP file, only one showed the assembly with all the subassemblies and the big part correctly. The other 2 did not show the subassemblies but they showed only the big parts.
Why did this happen? Does SW have a limit of total parts (including subassemblies) that can be exported to STEP?
The STEP files are below: use case 1 saved correctly (you can see the subassemblies) but 2 and 3 did not save correctly (no subassemblies). You don't even have to open them, just take a look at the size (1.4MB vs kilobytes).
