Xref problem

[ohiocad]

Have run into something new, that just has me stumped. (Running Acad 06)

Background on the issue:
I'm working on a 3-d wireframe layout of a building, just to get the geometry worked out, with a radius wall intersection a sloping wall, with another radius across the top of the parapet for both.

For ease of layout, I have xref'd an east wall section, and a north wall section into the base wireframe dwg. Both wall sections have been built using the exact same components, layers, blocks, etc, strictly 2-d.

Both xref's are Xclipped in the sheet, just to show the portion of the wall that I need.

Problem is:
Once I run the xclip command, one of them disappears, depending on my shade setting. If I have it set to 2d wireframe, the north section disappears. If I set it to 3d wireframe, or hidden, or shaded, etc, the north section appears, while the east vanishes. With xclip off, both show up.

No layer settings changed, nothing frozen or off. ANY ideas at all? PLEASE tell me it's a simple setting that I've just been too dense to see.

About bind bind the Xref drawings to turn them into block drawings and perhaps explode them into regular objects, to clip what you need. You may try refedit of the new block drawings to get what you need. I would perform these exploratory operations of copied Xref drawings.
