Use (list (entlast) p2) at place of p2: (list (entlast) p2) <=> at return of (entsel) (defun C:test1 ( / p1 p2 line1) (initget 1) (setq p1 (getpoint "\npick point1")) (initget 1) (setq p2 (getpoint p1 "\npick point2")) (command "_.line""_non" p1 "_non" p2 "") (setq line1 (entlast)) (command "_.lengthen" "_DYnamic" (list line1 p2) pause "") (command "_.change" line1 "" "_Properties" "_Color" "1" "") (prin1) )

This ? in dynamic mode... ((lambda ( / pt1 pt2 gap) (initget 1) (setq pt1 (getpoint "\nPick on 1st beam cl: ") pt2 pt1 gap 200 ) (while (equal pt2 pt1) (setq pt2 ((lambda ( / key pt alpha spane crnkL p1 p2) (princ "\nPick 2nd beam cl: ") (while (and (setq key (grread T 4 0)) (/= (car key) 3)) (cond ((eq (car key) 5) (redraw) (setq pt (cadr key)) (setq alpha (angle pt1 pt)) (setq spane (distance pt1 pt)) (setq crnkL (* 0.3 spane)) (cond ((and (>= alpha 0.0) (< alpha (* pi 0.5))) (setq p1 (polar pt (+ alpha ( * 0.5 pi)) gap) p2 (polar p1 (+ alpha pi) crnkL) ) ) ((and (>= alpha (* pi 0.5)) (< alpha pi)) (setq p1 (polar pt (+ alpha ( * 0.5 pi)) gap) p2 (polar p1 (+ alpha pi) crnkL) ) ) ((and (>= alpha pi) (< alpha (* 0.75 pi))) (setq p1 (polar pt (- alpha ( * 0.5 pi)) gap) p2 (polar p1 (+ alpha pi) crnkL) ) ) (T (setq p1 (polar pt (- alpha ( * 0.5 pi)) gap) p2 (polar p1 (+ alpha pi) crnkL) ) ) ) (grdraw pt1 pt 3) (grdraw p1 p2 1) ) ) ) (redraw) (cadr key) )) ) ) (prin1) ))

How about something like this, is that what you are looking for? (defun draw (pt1 pt2 len) (if (and pt1 pt2 len) (progn (entmakex (list '(0 . "LINE") (cons 10 pt1) (cons 11 (polar pt1 (angle pt1 pt2) len)) ) ) (entmakex (list '(0 . "LINE") (cons 10 (polar pt2 (angle pt2 pt1) len)) (cons 11 pt2) ) ) ) ) (princ) ) (draw (getpoint "\nFirst point: ") (getpoint "\nSecond point: ") (getdist "\nLine Length: ") )
