Drawing Rebar
Leonid Nemirovsky provided another utility for all to use called Draw Rebar Figure (Tip #2041). Here's a routine that works in early versions of AutoCAD as well as the most recent. A rebar (reinforcing bar) is a piece of steel placed inside concrete to provide additional structural strength. The placement of rebar is typically shown from the end of the bars with each bar represented as a solid circle. Len's utility provides an easy way to draw small, medium and large rebar solids. Load the LISP code into AutoCAD and type BAR at the command line. Next select the size desired, and locate the center point of the rebar. The program does the rest.
