imported shelled item problems

michael_lacasse

so i imported a shelled solid from solidworks (saved as an iges) and it turns it into multiple surfaces. Am I doing something wrong?

If you can, save the SW file to a different file type and import that. Try either parasolid or just importing the SW file directly. The translation may go smoother.

Yes IGES is notoriously bad.

I will try.. stay posted

I've had good luck using parts that have been exported from Onshape in the STEP format.  In my case the exported parts are usually machined via CAM software.

ok so it didnt work..... so i tried exporting from SW to iges then open that iges with SW and the model had all sorts of errors.  I might try and look at the solid model a bit more.

Try parasolid. Both Onshape and SolidWorks are based on the parasolid kernel (I think). So errors should be minimal.

@michael_lacasse please do not use IGES. It was discontinued in 1996. @mahir is right use Parasolid. If you use Parasolid there is NO translation so you get the exact geometry both ways. However if you're going from Onshape to SolidWorks set the Parasolid version to a lower number like 25. Onshape always uses the latest version of Parasolid - SolidWorks does not.
