Cannot assign section to geometry

[tgrimley]

I have some problematic geometry imported from SolidWorks as a parasolid. Part is a solid single cell when imported.

I've taken the geometry, partitioned it using datum planes, and then removed cells to end up with a shell with interior planes. At the intersection of two planes, I have some strange geometry which I cannot seem to repair or assign a section to.

Before I repair it, I need to figure out what it is.

It looks like a line, has two vertices and two "interesting points." When highlighting using query, geometry diagnostics with "apply to reference representation" ticked, nothing comes up. So that indicates it is not a free edge, solid cell, shell face, or a wire edge. I have the problematic geometry in a set and I am wondering what can be done now.

Anyone run into anything like this or have any more ideas what to check? Sort of at wits end. Oddly, it seems to mesh as a face, and when I zoom really really far in I can see distorted elements, but when viewing the geometry in the part module zooming in all the way it appears to be a line.

Pictures or posting a model would be most helpful. I have found the geometry repair to mainly be trial and error. Usually I try to fit it in the CAD program since typically it is an error on that end. I hope this helps.

Hi Rob, thanks for the reply.

Unfortunately I am not permitted to upload the model, but perhaps a few screenshots will help. I'm honestly not sure how useful they will be, but I will post them anyway.

The problematic geometry is created inside Abaqus/CAE by partitioning cells. I want to be able to change these plane offsets inside a python script, so I cannot create the geometry in Solidworks, unfortunately.
