Like everyone else our CAD files are filled with numerous layer filters. We have added the LFD.lsp and it works great. My question is whether I can somehow execute the command whenever I open a drawing. I tried adding this to my acaddoc.lsp file but it doesn't appear to be working. (DEFUN-Q S::STARTUP () (COMMAND "LFD") ) I would appreciate it if someone could tell me what I am missing. I apologize if this was answered in this forum elsewhere. Thanks.
