Set Paper Frame is a LISP routine by Raymond Rizkallah that enables you to set up a "sheet" in model space. This can be useful even if you normally plot from a layout. In some disciplines, you may not know which scale or paper size will provide the best results. This routine will essentially draw a border at a given scale and paper size in model space, quickly showing you the available limits. Start by loading the LISP file and running the command SETF. It will prompt you for a unit size, paper size, and paper orientation. This routine is written for various metric units, but the code is straightforward and could be adapted for imperial units fairly easily.
