In general, you can create a LIST according to the following method in LISP application:

(vl-load-com) (setq myent (car(entsel "please select a polyline 'n"))) (setq my-vla-obj (vlax-ename->vla-object myent)) (setq temp1 (vlax-get-property my-vla-obj 'coordinates)) (setq temp2(vlax-variant-value temp1)) (setq my-list(vlax-safearray->list temp2)) But, the return value of (vlax-get-property my-vla-obj 'coordinates) in ZWCAD is different from AutoCAD, which stops the (vlax-variant-value temp1) function getting the value of coordinates. We are trying to solve the problem, and the solution will be sent to you as soon as possible. Sorry for the inconvenient.

Hi, I tried to get LWPolyline coords using vlax functions but I can't convert the points to a list. I'm trying to migrate from ACAD but I have some little problems,as you can see . My code: (setq curba (entlast)) (setq curba_obj (vlax-ename->vla-object curba) coords (vlax-get-property curba_obj 'Coordinates) coords (vlax-safearray->list coords) ) The vlax-safearray->list leads to a "bad argument type" error. Please let me know how to solve this. Thx, ALin
