Raster images dissapear when drawing is transfered to another computer.

We do not save the raster image to a DWG file format. It is not saved in the FLX, DWG or DXF files. The raster images is only an overlay on screen, that we can see and print. If you are sending a DWG to a customer, you would also have to send them the raster image, with instructions as to where you need to have it inserted, so they can do so on their end in their CAD package.
