First, I'll apologize to everyone for asking such a stupid question, and if I'm aksing in the wrong place. I will preface this by saying that I know absolutely nothing about TurboCAD or any other CAD software for that matter. I have an old version (11.1) Deluxe that I recently acquired throught the purchase of some equipment. On to the problem....I'm attempting to modify existing dxf files, but no matter what I try my changes are not being saved. When I "save" it appears the process is taking place, however when I re-open the file it is back to it's original state pre-change. I've tried 'save as' and reanamed the file, but to no avail. I'm sure it is some small step that I'm doing incorrectly, but I'm out of my element with this software - just trying to teach myself as I go. Sorry to be such an idiot for taking up your time and thank you for any insight you might lend me.
