Question
I am looking for a lisp routine that will trim a line on a 2D drawing when I insert a block. this will be used on P&id's, so when I insert a valve symbol the line the block is being placed on would be trimmed away from one side of the block to the other
thanks in advance

That's sort of a complex question. I have something that will do that, but it's designed to work as part of a larger menu system and isn't easily seperated from it.
The approach is to insert the block, snap to line, auto-rotate, then temporarily erase the block and draw a circle the size of the area that needs to be trimmed. Then trim the underlying lines, and un-erase the block.
What I have for that won't work in your environment without a significant amount of work (beyond what I can do as a volunteer).

| Comment | Dear Mr. Cook, thanks for your time and expertise. Apparently when I created my new icons and instructed my computer where to search for the new data, I must have somehow deleted (which is bizarre to me), the support search path under options\tools, and therefore no response was being generated. A co-worker of mine helped me solve the problem. Once again, thanks for your response. I will definitely consult you on a future occasion if a problem does arise. Thanks! | ||

I`ve been using AutoCAD since 1987 and programming AutoLISP nearly as long. I can answer questions about programming AutoCAD (except ARX) and production enhancement techniques. I cannot answer questions about AutoCAD crashes or DWG corruption. AutoCAD PROGRAMMING (menus, lisp) related questions only!
