CAD links show incomplete data

Hi Forum,

I've been suffering from a CAD link problem where my AutoCAD "overlay" xrefs were unexpectedly showing in my Revit drawing (using version 2019) similar to this post:

https://forums.autodesk.com/t5/revit-architecture-forum/dwg-overlay-acts-as-attached/m-p/5941168#M104951

I decided to test the behavior in other version and ran into a completely different problem. In every version 19-23, the CAD add attachment was severely incomplete. In the screenshot you can see that only a tiny portion of the non-xref items (xrefs are dimmed) show in the revit model.

Does anybody know what the heck is going on?

View Range.

....ha! Actually, I don't understand what I'm looking for. Flat Stanley maybe?

- Is the DWG created in AutoCAD or a vertical flavor (AutoCAD Architecture or the like)?

- Have you tried to tick Current View Only box when link the DWG?

Nice to have the top guns on this! Thanks for looking at it.

The drawing was done in AutoCAD, some portions were exported from Revit at one time, but nothing else.
I didn't use Current View Only since it never occurred to me that it might make a difference. Can it?
Barth, The AutoCAD dwg is shown so you can see that outside the circled area there are lots of other elements that should also be showing when linked. I linked the CAD into 4 separate version of Revit (19-23) to see if there were any differences in behavior.

Regards,

James

- Tick Current view only when linking effectively make the DWG a 2D detail (detail lines) so it will show regardless of your view range and you can set to display in foreground or background. It's useful if your DWG is for tracing or referencing on a plan.

- Untick Current view only makes the DWG a 3D model (model lines) with its Z elevations stay intact. It is useful when the DWG is a 3D CAD such as a topo map.

I found the problem. The portion of the plan that was visible was a mile from the rest of the plan due probably to a bad cut-and-paste job. The rest of the plan was all there, but far away.
