Subdivide Lot into Desired Areas divides a subdivision lot into the specific areas you desire, equal or unequal. This tip continues the theme of an expert drawing system by automating tedious work. Take a look at the included JPEG image for a better understanding of this tool. Start with a simple lot layout, and this routine will divide it into equal areas following a generally horizontal route through the area. When you've defined a basic lot, draw an Xline through it, then load the LISP code. Type AS at the AutoCAD Command line to activate the utility and follow the prompts. Although not useful for everyone, this code is nicely done and illustrates how LISP can solve problems of this nature.
