Tip author Azfar Mahmood updated a tip published in 2001. The original tip, No. 1719, is described as "Breaks crossing lines on P&ID process flow diagrams at a distance you specify." The improved version does the same thing, except in a dynamic mode. Start by loading the LISP routine, then run the command WIRBRK. Specify whether you want horizontal or vertical breaks, and specify a break distance. Now it's time for the dynamic part: As you move the cursor near the intersection of two lines, the appropriate line is broken and the gap is filled in with a jump block. Press Enter to stop. Azfar has included a sample drawing with this routine also. If you run this routine in your own drawing(s), you will need to first create a block named JUMP, or use the one included in the sample drawing.
