In regards to autolisp . . . I am having a problem when using the trim command on either a pline or line to trim inside the circle when the circle and the end of the line are off the visible screen. In other words when I (setq pt1 (getpoint "\nPick first point)) (command "circle" pt1 . . . . (setq cir1 (entlast)) (setq pt2 (getpoint "\nPick second point)) (command "trim" cir1 pt1 . . . If the circle and end of line is visible, then the line will trim but not if I have zoomed in on the other end of the line. ??? Thanks in advance Charly
