If you have ever had an AutoCAD drawing in which you execute Zoom Extents and your drawing disappears, then this LISP routine might be for you. Sometimes you can find and remove an offending entity that causes the Zoom command to appear to misbehave, but other times you just need a quick solution. With its special Zoom Extents command, Jim Dee's LISP routine allows you to define an area in your drawing that will never be exceeded. This routine includes a dynamic rectangle block that you place in the drawing and size to your needs. Load the LISP file, then run the command ZB and the drawing will zoom to the exact area of the aforementioned rectangle block. |
