jes_g Posted January 29, 2018 Share Posted January 29, 2018 (edited) Hi all, I found this LISP routine by Tony Hotchkiss from here. If I understood this correct, it works with LWPolyline, Polyline and Point. For some reason it does not work will all polylines on my drawing. The sample drawing is provided below and attached with this thread https://drive.google.com/file/d/1bLurrxbnH6c9Fee5L4qIc0okwdVU0b9W/view?usp=sharing (defun vert (/ filterlist vla-obj-list lwlist 2dlist ptlist vlist1 vlist2 vlist3 ) (vl-load-com) (setq filterlist (make-filter) vla-obj-list (get-objects filterlist) lwlist (nth 0 vla-obj-list) 2dlist (nth 1 vla-obj-list) ptlist (nth 2 vla-obj-list) vlist1 nil vlist2 nil vlist3 nil ) ;_ end-of setq (if lwlist (setq vlist1 (make-list lwlist 2)) ) ;_ end of if (if 2dlist (setq vlist2 (make-list 2dlist 3)) ) ;_ end of if (if ptlist (setq vlist3 (make-list ptlist 3)) ) ;_ end of if (write-text vlist1 vlist2 vlist3) (princ) ) ;_ end of vert (defun make-list (p-list n / i vlist obj coords ca j x y z xy) (setq i (- 1) vlist nil ) ;_ end of setq (repeat (length p-list) (setq obj (nth (setq i (1+ i)) p-list) coords (vlax-get-property obj "coordinates") ca (vlax-variant-value coords) j (- 1) ) ;_ end-of setq (repeat (/ (length (vlax-safearray->list ca)) n) (setq x (vlax-safearray-get-element ca (setq j (1+ j)))) (setq y (vlax-safearray-get-element ca (setq j (1+ j)))) (if (= n 2) (setq xy (list x y)) (progn (setq z (vlax-safearray-get-element ca (setq j (1+ j)))) (setq xy (list x y z)) ) ;_ end of progn ) ;_ end of if (setq vlist (append vlist (list xy))) ) ;_ end-of repeat ) ;_ end-of repeat ) ;_ end-of make-list (defun make-filter (/ filter) (setq filter '((-4 .

Or maybe my drawing can be modified using another LISP routine. In addition, I want the program to output two files. The first file would be the XY coordinates of all points of the polylines with number (kind of identification). For example, Node X Y1 359.663 162.816 2 358.596 163.075 3 358.481 163.08 4 358.379 163.045 5 358.305 162.987 6 358.234 162.857 7 355.779 153.074 8 355.753 152.623 9 355.753 152.247 10 355.804 151.921 The second file would include the points and distances between them. For example, Node_start Node_End Distance1 2 1.097984517 2 3 0.115108644 3 4 0.107837841 4 5 0.094021274 5 6 0.148124947 6 7 10.08633303 7 8 0.451748824 8 9 0.376 9 10 0.32996515 10 11 0.246221445 Thank you Best wishes, Jes G Sample.dwg Edited January 29, 2018 by jes_g attached file Quote Link to comment Share on other sites More sharing options...

BIGAL Posted January 30, 2018 Share Posted January 30, 2018 Did you ask for this before or maybe at one of the other forums, theswamp, Augi, pretty sure seen this request previously. An answer was provided. Quote Link to comment Share on other sites More sharing options...
ronjonp Posted January 30, 2018 Share Posted January 30, 2018 One issue is that drawing contains 139 lines in it and the code does not account for them. Quote Link to comment Share on other sites More sharing options...
