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

Hi Charlie, you've wandered into the wrong Autodesk forum, in the future you should adress your questions to the AutoCAD forum (go acad) instead of the Autodesk Software forum. I do have an answer for you, but you probably won't like it. The object selection commands don't work on objects that are outside of the virtual display. There is no way around this other than to zoom out again OR get a really good display list program that keeps all the potentially visible geometry in the virtual display and prevents the regens that cause the virtual display to change size. -GB-
