I recently stumbled across (by mistake) and interesting AutoCAD XREF trick that I was unaware of. In fact it provides an instant solution to a problem I do come across now and again so I thought I would share.
The tip is with regards to changing and Attached Xref to an Overlayed Xref and visa versa.
My guess is that 90% of AutoCAD users are unaware of this tip.
The tip is:
In the XREF dialog box if you double click the word Attach or Overlay in the'Type' column (as seen above) you can actually toggle the xref from being Attached to being Overlayed, and visa versa. This can help eliminate a Circular Xref error. This click behaviour in a dialog box is unusual forAutoCAD, and I don't think it would even occur to an experienced AutoCAD user to try this.
So now I will start double clicking in other dialog boxes and see what other treasures lie within.
As most experienced AutoCAD users know, an attached Xref WILL travel with the host file if it is further Xref'd but an Overlayed Xref will NOT travel forward with it's host file if it gets further Xref'd.
