I have a drawing that is giving me the following error when I open it. It never had this problem when my company had 2008. We skipped 2009 and now we have 2010 and ever since we upgraded this error has been popping up.

"Relations exist which create a circular update path between Drawing View1 and Drawing View18. Sketch geometry may update improperly. Remove the relations which cause the circular update path."

If I force rebuild the above message pops up again and a second that reads the same except the order of View18 and View1 are switched in the same statement.

The odd thing is that there is no View18 in this drawing.

Does anyone have any idea what could be happening and guide me in the right direction in fixing this?

Thanks in advance!

Chris
