Is there a way to ignore/turn off sheets when saving a file? 

It seems I cannot delete sheet 1.

This is giving me a problem when I upload to windchill. The drawing comes in as a multiple page document with the first page being the model space and one additional page for each sheet in the drawing. So I end up with a multiple page doc with the same content repeated on each page.

If I delete the viewport in sheet 1 I still get a 2 page doc with a blank page for pg 2.

Help!
