Hello to anyone ! I work with Acad 2005. How can I save multiple opened DWG files , as DXF all together ? I explain better : 1 ) Open several DWG files with multiple selection with "OPEN" dialog. 2) I need to save same files ( with same names ) in DXF format "all ensemble". Where can I find same samples or LISP code to do this ? ( retrieving current DWG filename, also without extension, etc. ) How can I do this ??? Tnks for all.... Genesio
