The routine problem is this. I have a drawing of a model reference, driven multiconfiguration by a DT linked to an external spreadsheet. Upon reloading a drawing, with apparently a full rebuild or not lightweight or anything like that, the drawing information is still out of date: CTRL-B,Q,R has no impact here. As a workaround, I have to open the model reference, and even load/edit the embedded DT, which is all a process! When I load the embedded DT and close down, I am not even reliably returned to the SW session! Is there a better workflow then this? Also, I find that if the linked spreadsheet is in memory in Excel, I get SW message and resulting action to create a new external spreadsheet file: Is that normal?
