Multi-body step file export

wesley_astinwesley_astin Member Posts: 7
I'm pretty new to Onshape (solidworks user for 12 yrs).  I'm evaluating the software and looking for potential hang ups.  one thing i noticed is when i create a multi-body PART (not assembly) in ohshape, export as STEP, and open in solidworks; it comes in as an assembly and not a part.  Is there any way to export the step so that it opens as an .sldprt file with multiple bodies instead of an assembly that would need to be remated or fixed parts?

    This sounds like an issue with SW, not OS. SW has an option to import multi-bodies as separate parts. Make sure that option is disabled.

    that box is unchecked.  i made a quick part in Onshape, exported it as STEP, and when it opens in SW, it is an assembly with two parts.  see link below onshape part:

    Hmm. Odd. When I need to export to SW I use Parasolid. This hasn't been an issue with that file type - probably because both SW and OS use the Parasolid kernel.

    Would definitely use parasolid for going between the two.

    Also, you can always save your SW assembly as a part, which will end up a multibody part.

    using parasolid is not an option.  we have to use STEP due to current customer preference.  I believe for now we have settled on the customer can save the imported model as a sldprt instead of an sldasm if they would like.  Thanks.

    The customer might be convinced otherwise if they were informed that parasolid will always be the best choice when working in SolidWorks. Some companies just stick to what they're comfortable with, but it's not necessarily what works best. I bet there are still plenty of companies that prefer to use IGES just because that's what they're accustomed to using.
