  1. hai, i need a small help.i have a working lisp routine which gives perpendicular line distance to main line when clicked on a place perpendicular, only thing i want to try and add is to remove the leader that adds and only add text without leader in position where i can click. pls reply if its possible... thanks:) (defun c:Test ( / s p c a d) (if (and (setq s (car (entsel "\nPick a polyline :"))) (or (= (cdr (assoc 0 (entget s))) "LWPOLYLINE") (alert "Invalid object! Please pick a polyline only.") ) (setq p (getpoint "\nSpecify point perpendicular to polyline :")) (setq c (vlax-curve-getclosestpointto s p)) (setq a (angle p c)) (not (grdraw p c 1 -1)) ;; rubber line in red colour. (setq d (angle '(0. 0. 0.) (vlax-curve-getfirstderiv s (vlax-curve-getparamatpoint s c)))) (or (or (equal (rem (+ d (* pi 0.5)) (+ pi pi)) a 1e-4) (equal (rem (+ d (* pi 1.5)) (+ pi pi)) a 1e-4) ) (alert "Picked point is not a perpendicular to picked polyline. <!>") ) ) (command "_.leader" "_non" p "\\" "" (strcat "CHAINAGE=3+0" (rtos (vlax-curve-getdistatpoint s c) 2 4)) "") ) (princ) ) (vl-load-com)
