Hello Bill, Gerry,
Problem, I produce a drawing and save as, then I click Export and change into a DXF file so that it will produce a G-code in Mach2, when I try to close Autocad a window appears informing I have changed the drawing do I want to save, if I click yes, autocad will not close, if I click no, autocad closes, but when I open autocad again the original drawing has been deleted, this is a nuicence, because perhaps I would like to change something in the original drawing, is there something in autocad that I can do to rectify this?,
