Hello everyone. I have trouble to split up one dwg into other dwg which object is only inside the boundary. I have done with this method: create boundary (by closed polygon) to which object I want to save-trim outside boundary-save as the modified dwg-undo to previous dwg (so i get back my original dwg objects) and repeat to the first step. Is there any lisp to solve my problem? It takes too much time with my traditional method. Thanks in advance.
