I've written a lisp utility to set multiple layout tabs to a Page Setup (saved in the drawing). It seems to work fine - see this thread: http://forums.augi.com/showthread.php?t=80461
Unfortunately in some cases the page background is not updated (even after re-opening the drawing). The Page Setup Manager does show that the tab is set to the correct Saved Page Setup, but when the setup refers to Plot area = Extents it doesn't "move" the page background in Paper Space. I then have to do the Set Current in the Page Setup Manager and after clicking Close it updates correctly.
The plots do come out correctly even if I haven't performed the above, but I'd like to see it as it's set-up. Does anyone know how I can "update" the display of the Page in Paper Space after setting the Layout to a particular Page Setup?
