Original file imported as a step at 11 mb with parts modified slightly is exporting as a massive 5.7 gb file no matter which format is chosen. In a related note, either parasolid file can no longer be opened in Inventor. File size also seems quite large considering the number of bodies and how simple they are at 47 mb.
Please let me know what other information I can provide. It seems to have started with the most recent update.
