Tony, I found this little routine on a PC running AutoCAD, and I can't understand what the ^u is doing in the file. There are two of them, here's one: ;FILE NAME: arrow.lsp ;========================================================== (defun C:ARROW () (setq *error* mherror) (savevars "CMDECHO") (setvar "CMDECHO" 0) (savevars "clayer") (makel "TEXT100") (setq from (getpoint "\nArrow Start at: ")) (setq to (getpoint from "\nArrow Ends at: ")) (command "dim" "leader" from to ^u) ; HELP !!!!! The above line is driving me crazy (command "exit") (setq x (- (car from) (car to))) (setq x (/ x 2.)) (setq y (- (cadr from) (cadr to))) (setq y (/ y 2.)) (setq a (angle from to)) (setq centre (list (- (car from) x) (- (cadr from) y))) (setq pipi (/ pi 2.)) (setq centre2 (polar centre (+ a pipi) 10)) (command "mirror" from "" centre centre2 "n") (setvar "CMDECHO" 0) (resetvars) (princ) ) I have no idea where it came from, someone programmed it in and I was just helping out… Mark <Baffled?> Kurdi
