I have a LISP routine that needs modifications. I am not at all literate in this language. I used the routine at a previous location. Now I am somewhere else and the layer system is different. The command would take objects from an existing layer to a demolition layer, new layer to demolition layer, new layer to existing layer and so on. You will also see reference to Rev A and Rev C, that is no longer used. I can provide the current file to be modified. Can anyone help me? Thanks in advance.
