Can anybody please help with the following?
I am trying to make part of a raster image (Tiff), green with the following method.
1 - Create a new green layer
2 - Create a REM of the objects i want green and put them on green layer.
3 - Convert the REM back to the raster image.
I now have a raster which is part green and the rest black.
When i plot this drawing everything is fine but if i close autocad down and reopen the drawing the preview looks fine but when the drawing opens the green parts have changed back to black.
How do i keep the green parts green when i reopen the drawing?
Many thanks in advance for replies
