Derek Beals submitted Ze-all-sheets, a routine that iterates each layout in the current drawing, performing a zoom extents. Derek uses this before saving the drawing to ensure that each layout is fully displayed. To use the main function, load the LISP file, then start the command by entering ZEAS at the Command line.
As a bonus, Derek has included several of his standard functions for tasks such as converting radians to degrees and rounding a real number to the next whole integer. These standard functions include descriptive comments. Thanks for your submission, Derek.
