Moving Raster Images in AutoCAD^® r14
Comments by: Odin Cary

If you attempt to move raster images around on your screen and align them with vector objects, you quickly discover that when you select the raster image, you can't see anything within the image frame. This can be rather annoying to deal with and does not need to be so.

AutoCAD has had a variable called "HIGHLIGHT" for as long as I can remember and that is what causes the raster images to appear over the vector lines on your screen. Type in HIGHLIGHT and set this system variable to 0 (zero, for off) and then move your raster image around the way you would like to. Don't forget, that this variable controls all highlighting of selected objects and you will need to set it back to 1 for normal work.
