I am contacting you because during the drawing of an exploded one it "pox".
When reopening the drawing, it refers to a room that it cannot find. This element is not present at all in the entire case file. So it is unknown and no files have been renamed recently, which could lead to this kind of error.
Despite the insistence of clicking on "cancel" and finally accessing the plan and understanding what is going on (and then looking for any missing file) nothing helps. It seems that the file may be trying to replace all the elements with the one it is looking for.
On the other hand, the opening of the assembly corresponding to the plan is not a problem.
Hello; Do you have any configurations in your assembly? Maybe your missing components are there? It is also possible that they are missing or unresolved external references (identifiable by the mark (->*) in your build tree. To search and identify them (external refs)Right-click on the Name of your assembly in the construction tree/External references...
