Tony,
Thanks for reply -- AcadXTabs looks like what I want. I have a couple of questions:
1) My drawings are generated using both VB.Net and VB6 (not human drawn) -- can I manipulate AcadXTabs programmatically? What I really want to do is populate the menus with a variable listing of drawing names -- both count and name.
2) generally, the drawings are not saved since they can be regenerated from database values at will. However, users will look at drawings on the screen (to compare them to what is expected based on the product specified on a quote). Can I specify my own tab caption (file name?) - e.g. "Quote Line 2", "Quoter Line 3"," Details for Lines 2 & 3", etc. without actually saving the drawings.
