First of all - thanks for all the wonderful CAD tips you share with others.I have a problem that could be probably solved easily but I have not found a solution yet. Whenever I switch to a viewport in any layout, AutoCAD does ZOOM All and my drawing is zoomed to the limits. Is there a way to avoid this?Thanks again.

Hi,
the Zoom problem can be solved by locking the viewport or by setting the UCSFOLLOW variable (layout specific) to 0.
