Autodesk added some smoke and mirrors with their 2006 release of AutoCAD. Previously you could set IMAGEFRAME either to “0″ (invisible border or frame), or to “1″ (visible border of frame). In 2006 we are now presented with a third choice of “2″.
If IMAGEFRAME is set to “2″ then you will see the frame when working in your drawing, but the border will not plot. Keeping with the theory that “2″ is better than “1″, and certainly better than “0″, IMAGEFRAME set to “2″ gives you the best of both worlds.
