Ajmal Posted May 17, 2020 Share Posted May 17, 2020 how can I change “GETPOINT” z-axis value? I need always z-axis value “0”. Because when I am taking with getpoint, one line distance if the line has z axis that also it will come to that length. Am drafting 2d I don’t want 3d. so when I will get the quantity it's coming wrong (defun c:test() (vl-load-com) (setq acadobj (vlax-get-acad-object) doc (vla-get-activedocument acadobj)) (setq pt1 (vla-getpoint (vla-get-utility doc) nil "\nPick 1st point for length") pt1v (vlax-variant-value pt1) pt1zv (vlax-safearray-get-element pt1v 2)) (vlax-safearray-put-element pt1v 2 100.00) (setq new-zvalue (vlax-safearray-get-element pt1v 2)) (setq pt2 (vla-getpoint (vla-get-utility doc) nil "\nPick 1st point for length") pt2v (vlax-variant-value pt2) pt2zv (vlax-safearray-get-element pt2v 2)) (vlax-safearray-put-element pt2v 2 100.00) (setq new-zvalue (vlax-safearray-get-element pt2v 2)) (entmake (list (cons 0 "line")(cons 8 "01-identity")(cons 10 pt1)(cons 11 pt2)))) Quote Link to comment Share on other sites More sharing options...
hanhphuc Posted May 17, 2020 Share Posted May 17, 2020 (setvar 'osnapz 1) ; 2D (setvar 'elevation 100.) ;plan elevation (defun c:test ( / pt1 pt2) (ai_sysvar '(("OSNAPZ" . 1)("ELEVATION" . 100.0 ))) (and (setq pt1 (getpoint "\nPick 1st point for length ")) (setq pt2 (getpoint pt1 "\nPick 2nd point for length ")) (entmakex (vl-list* '(0 .

BIGAL Posted May 18, 2020 Share Posted May 18, 2020 hanphuc provided a good solution sometimes the point is xyz but Autocad input is XY so a simple work around is (setq pt1 (getpoint "\nPick 1st point for length ")) (setq pt1 (list (car pt1)(cadr pt1))) Quote Link to comment Share on other sites More sharing options...
