Corridor Section Editor Problem

If you exit out of a drawing while utilizing the Corridor Section Editor command you may find that all of your objects have been hidden, or have disappeared, in model space. In a few steps we can fix the problem.

First type View at the command line. Next change the Clipping value for the current view to Off.

Next set the UCS to World then set the view to Top.

Your drawing should then be back to normal.
