I have an addIn that can help users input drawing's data. These data are written in custom ipropertes, which are linked to the titleblock. My problem is that it takes time(about 5 seconds) to refresh the titleblock via drawingDocument.Update method. But if I save the file or enter the iproperties and then exit again, the titleblock refresh immediately. How can I refresh the titleblock quickly?
