Hello, This is just a wild thought but, Is there a lisp or program that´ll does the following (or is it possible to create such a lisp): When I attach xref file into a drawing and want to make a detailed drawing of part of it I do the following: I create a viewport in paperspace and zoom to the part I want to make the drawing of. I turn off the layers (usually text) of the xref file and make the drawing. When the drawing is finished I plot it. The other designers usually want to have the cad file also...this is where it gets complicated. I don´t want other designers to see all of the xref file. I usually bind it, explode it and the trim the rest of the drawing away. It takes time to do this + the layers have to been turned off again. What I would like the program to do is this: When I have this detailed drawing with xref I´d want to bind the xref drawing so that only the part of the drawing that shows in the viewport is bound. So the program would automatically erase the rest of the drawing. Am I daydreaming or is this possible? Thanks, Pekka
