Hi, i've a problem: i've one LSP file, which has my own customized shortcut commands inside, with the content like this: (defun c:c( ) (command ".copy") ) The usage of above is to use the shortcut commands i like on other person's computer, C now stands for Copy, but the problem is when i finish my job, and let other guys continue, they don't like it , they still want use C for Circle. so, i need reload the DWG file so autocad can load command definition from acad.pgp, which is a little troublesome. So anybody can help me restore the definition of acad.pgp without reloading? i.e. cancelling the lsp definition. note: REINIT command can NOT restore the command defined by (defun). so how? Thank U!
