Hello, I was working in a drawing yesterday and recieved this error message when trying to get the ducts to show up from an xref created with AutoCAD MEP 2008. I am running on ACA 2008. The duct would not show up, so I went into the display manager/ representations by object/Duct and then tried to put check marks in the boxes on the 'Plan' line item. When I hit OK I get a fatal error everytime with the same error message. I have tried seraching the net and found no solutions. Any help would be greatly appreciated. I can also possibly upload a partial of each drawing, but my company is very protective as we sign copyright agreements with most of our clients.
Thank you,
Mike
