HelplessIntern Posted June 9, 2016 Share Posted June 9, 2016 I have just started learning AutoLISP from different posts on the forums and through the reference material from Autodesk but, I am hitting an error in my lisp routine that I don't know how to fix. I am trying to right a while loop that will go through a nested list and use information in the selected list segment to find points in reference to a Polyline using the vlax-curve-* functions. Currently I am using the vlax-curve-getPointAtDist with a variable distance and using a user defined polyline from the document. My code runs up until the point I try to use the getPointAtDist line which will return the error of "unable to find ObjectID for . The way I get the polyline from the user is a (setq Var (ssget "_+.:s" '((0 . "*POLYLINE")))). I have earlier in the routine the vla-load-com to load in all of the functions of visual lisp. Can anyone help me out on what I need to do to be able to run the vlax-curve-* functions? Quote Link to comment Share on other sites More sharing options...
