You can use "member" in place of vl-position. It's just that "vl-position" is just slightly faster than "member". It accepts exactly the same arguments as "vl-position". As for vl-remove-if-not, I don't think there's another. You just have to make one: (defun vl-remove-if-not2 (fnc lst / rtn) (foreach x lst (if ((eval fnc) x) (setq rtn (cons x rtn)) ) ) (reverse rtn) )

Just copy it using vla-Copy and then move it using vla-Move (although this uses VLisp) ;; ent - entity object ;; pt1 - base point ;; pt2 - move point (defun pl (ent pt1 pt2) (vla-Move (vla-Copy (vlax-ename->vla-object ent)) (vlax-3d-point pt1) (vlax-3d-point pt2)) ) If you want just the coordinates: (mapcar 'cdr (vl-remove-if-not '(lambda (x) (vl-position (car x) '(10 11))) (entget pl)))

Hello, try this if you want (setq sset (ssget '((0 . "LWPOLYLINE")))) ;;;;;;;;;;;;;;;; ;repeat for n selected plines (repeat (setq i (sslength sset)) (setq nam (ssname sset (setq i (1- i)))) (setq ent (entget nam)) (setq entD ent) (setq tt (assoc 10 entD)) ;;;;; ;Create list from X Y (while (/= nil tt) (setq all (cons tt all)) (setq entD (vl-remove tt entD)) (setq tt (assoc 10 entD)) ); end while ) (setq all (reverse all)) Hope to help you if dont work i will modify it.

You're right, I opened Pandora's box and now I can't handle it, sorry for that.

Another one (defun disspacify (str / regexp) (if (setq regexp (vlax-get-or-create-object "vbscript.regexp")) (progn (vlax-put-property regexp 'global actrue) (vlax-put-property regexp 'pattern " +") (vlax-invoke regexp 'replace (vl-string-trim " " str) " ") ) ) ) _$ (disspacify " This is a normal string.

@motee-z Here's a revised version that adds text to the face with the slope value. It also checks that the firsts 3 vertices of the face are not duplicates.

If you want half the vertices can just get the all vertice XYZ save start and end then skip every second one, put back the new vertices. VlA-PUT big hint.
