mariarfd posted a topic in AutoLISP, Visual LISP & DCLHello, I recently discovered the potential in acad with lisps, and first of all I want to thank all the people sharing their knowledge (specific thanks to Tharwat and GC gile)! I am completely ignorant regarding what seems like programming here, but I am very willing to try and learn (allready succeeded in changing a parameter in a lisp all by myself!) The facts are: I have lots of closed 2d polylines (or lwpolylines, doesn't really matter because I have learned how to turn my polys into lwpolys). I have to extract their area, layer and coordinates, in a way that each polyline's data can be identified in the resulting file. I started by researching a way to automatically name the polylines, not much luck, so I am determined to enter numbers manually in the hyperlink field for each polyline. I have also found a lisp that extracts hyperlink, layer and area for multiple polys at once, which is a great first step (as a newbie I am not sure if I can post the link here). What now remains is to extract each poly’s coordinates together with its hyperlink. Do you think it is doable to invent a routine and achieve this for many polylines at once? Alternatively I will have to list and copy paste the coords for each polyline separately... for 400 polylines ... and then again in another similar dwg... etc. Sorry for the large thread, I hope I explained properly – and sorry if the answer already exists somewhere, I did my best to find it but didn’t (I did find quite some lisps to export coords, without separation per polyline and without hyperlink. Maybe someone experienced could alter these to include the extra data, but this is not my case…) Many thanks in advance to all the helpfull inlightened people here, Maria
