I cannot open the Revit Model because of the next Error :
There is a circular chain of references among the highlighted elements.
May you can help me with this.
Expand the error dialog.
Check the box next to one of the elements.
The "Delete Elements" button shuold be enabled in the Error Dialog.
Delete the affected elements, and you should be allowed to continue.
Usually there is nothing you can do but to exit out and try again....or as Joe mentioned delete the object causing the issue (most often its over-modeled floors (ie lots of openings and islands)
I've had to remodel many floors over the years with this issue.
