benhubel Posted May 4, 2016 Share Posted May 4, 2016 I love Extrim, but it only does one trim at a time. I am looking to trim everything that is selected at once. The pseudocode goes like this: 1. Get selection 2. Filter out everything but closed polylines 3. Ask user if they want to just trim crossing lines, or to delete everything 4. selected on that side of the line. 5. Get a point as the side to extrim on. If inside any selected polyline, get the inside point of each polyline and then trim inside each one (or inside the boundary of any crossing ones). Likewise, if outside of all selected polylines, trim the outside of each one (or outside the boundary of any crossing ones). My main problem is that I have no clue what I'm doing when it comes to dealing with Extrim. The syntax keeps throwing me around. I thought it would be super simple when I started, but because Extrim is a LISP rather than a command, it's got me really confused. I was planning to make use of alanjt's SelectWithinCurve routine to help with deleting non-crossing geometry. Quote Link to comment Share on other sites More sharing options...
