Title: Offset line and trim/extend
Post by: DanB on March 14, 2023, 02:22:01 PM

I have a situation that comes up frequently. A radial line is offset to two sides and needs to be trimmed and extended to arcs. Current method is to quickly break the lines so they are visually obviously incorrect, and then extend to the corresponding arc. This way I know they are not extending beyond the arcs. Note in most cases it is a very subtle extension but I've provided a screen capture that is in an exaggerated state. Any suggestions on a faster or even automated (LISP) process?

Why don't you use double XLINES and then just EXTRIM (etrim ptinside) + (etrim ptoutside)...
