So I have had this issue randomly for some time now. It has persisted from Creo 2 M060 to the M200 release I am currently running, even persisting across multiple computers. In rare instances (could be a part drawing, could be assembly drawing) then the model is altered the drawing does not update the views. No amount of regeneration updates the views. So far the only consistent way I found to get the views to update was to rename the views (and then rename them back). That sort of works but it means that every single drawing view (incl. detail and section) has to be renamed and renamed back to verify that the changes in the part/assembly show up on the drawing.
It really is strange, and no one here has been able to figure it out. any ideas?
thanks
Greg
