Reducing exported file size
I need to export an assembly for multibody simulation outside Onshape. I need the parts in individual STEP files and these should be as small as possible. Sadly, some files are exceedingly large. I can improve things by removing some geometric detail---fillets and chamfers being prime candidates---but this takes me only so far.
Any tips on how to tackle this? The offending parts can be over 20 MB in size and... I need to shrink them... tenfold. Yeah. Are there specific geometry features that tend to massively bloat STEP files? Also---is there a way to automatically remove all the fillets (if not also chamfers) from a part for export? Any chance we might get this option in the future?
An observation: I know patterns tend to bloat files but often they are important and you can't simply delete them or suppress them for export. Do STEP files explicitly specify geometry for each pattern instance or do they specify it for one instance to then reference it for the other instances?
Thanks for whatever tips and bits you an share!
