[Bug Report]complex .stp model doesn't import correctly.

I just signed up today and wanted to provide feedback regarding a bug I discovered. I tried uploading a .stp (STEP) model I exported from 123D Design version 2.1 and there appears to be a surface missing from the model as displayed by OnShape after uploading.

Here's how the model should look (and how it does look in a 3rd party nurbs modelling application, MOI3D):

And how the model looks in OnShape :

You'll probably need the .stp file for duplication of the issue and you can get it from here :


I hope this is helpful in tracking down the bug.

Thank you for your time and consideration.

Best regards.

    Hello, thanks for your reply and letting me know about that. I submitted the bug report from the CAD section of the site.

    Unfortunately, I only joined yesterday to try out Onshape and get an idea of what its capabilities are and this bug precludes me using it, at least for the time being. But it didn't sit right with me not to report it so that it can be fixed and OnShape be better for it.

    Thank you for your time and consideration.

    Best regards.
