Here's another - (defun c:ppl ( / ent idx pnt sel ) (if (and (setq sel (LM:ssget "\nSelect points: " '(((0 . "POINT"))))) (progn (while (progn (setvar 'errno 0) (setq ent (entsel "\nSelect curve: ")) (cond ( (= 7 (getvar 'errno)) (princ "\nMissed, try again.") ) ( (null ent) nil) ( (vl-catch-all-error-p (vl-catch-all-apply 'vlax-curve-getclosestpointto ent)) (princ "\nInvalid object selected.") ) ) ) ) (setq ent (car ent)) ) ) (repeat (setq idx (sslength sel)) (setq idx (1- idx) pnt (assoc 10 (entget (ssname sel idx))) ) (entmake (list '(0 . "LINE") pnt (cons 11 (vlax-curve-getclosestpointto ent (cdr pnt))))) ) ) (princ) ) ;; ssget - Lee Mac ;; A wrapper for the ssget function to permit the use of a custom selection prompt ;; msg - [str] selection prompt ;; arg - [lst] list of ssget arguments (defun LM:ssget ( msg arg / sel ) (princ msg) (setvar 'nomutt 1) (setq sel (vl-catch-all-apply 'ssget arg)) (setvar 'nomutt 0) (if (not (vl-catch-all-error-p sel)) sel) ) (vl-load-com) (princ)

Yes, for example like this: ... (setvar "nomutt" 1) ;; shut up ssget (setq en (ssget (list (cons 0 "ARC,CIRCLE,ELLIPSE,LINE,LWPOLYLINE,POLYLINE,SPLINE") )) ) (princ "\nSelect Points: ") (setq pts_ss (ssget (list (cons 0 "POINT")))) (setq ss_len (sslength pts_ss)) (setvar "nomutt" 0) ;; set the variable back ...

My code used to do a similar thing (you can find it in the list of my replies on this forum): move blocks perperdicular to multiple polylines, first find the closest polyline to the block. I changed it to select points, and to draw lines instead of moving the blocks. I think it does what you require, but it has remnants of the old code, so it has lines of code that are not needed anymore. So if you select multiple polylines it will draw a line to the closest one. - Command STO (feel free to change this) - select polyline(s) -select points (defun Line (p1 p2) (entmakex (list (cons 0 "LINE") (cons 10 p1) (cons 11 p2) ))) ;;; Modified code from: http://www.arch-pub.com/Move-point-perpendicular-to-line_10272335.html ;;; By: Mel Franks (defun c:sto ( / en obj pts_ss ss_len c pten ptobj pted pt pt2 this_is_the_point best_distance) (princ "\nSelect polyline: ") (setq en (ssget (list (cons 0 "ARC,CIRCLE,ELLIPSE,LINE,LWPOLYLINE,POLYLINE,SPLINE") )) ) (princ "\nSelect Points: ") (setq pts_ss (ssget (list (cons 0 "POINT")))) (setq ss_len (sslength pts_ss)) (setq c 0) (while (< c ss_len) (setq pten (ssname pts_ss c)) (setq ptobj (vlax-ename->vla-object pten)) (setq pted (entget pten)) (setq pt (cdr (assoc 10 pted))) (setq cnt 0) (setq best_distance 1000000) ;; and we will search for something better.
