When you create a REM object, it is associated with an image. Any AutoCAD command that changes the geometry or location of a REM object causes the REM object to dissociate from the image. Such commands include MOVE, SCALE, ROTATE, and ERASE. REM Smooth also causes a dissociation. For more information, see Smoothing REM Linework.
If the geometry or location of your source image changes, the associated REM objects adjust accordingly. For example, if you move an image to a new location, all the REM objects associated with the image move with it and are not deleted. If an image is erased or unloaded, all the REM objects associated with it are also erased.
If you define a rectangular region as a REM object and then move it, the original raster data in the source image is deleted.
If your REM primitive or enhanced bitonal region is defined over an intersection, the intersection is preserved even after you MOVE the primitive object.
In order to save your changes to your REM objects, you must either merge the objects into an image, or create a new raster image from the objects. For more information, see Merging REM Objects into an Image and Converting REM Objects to a New Raster Image.
REM objects cannot be plotted.
