After defining a region object or a primitive object, you can use a variety of commands to modify the raster data.
You can use the Merge To Raster command on a modified REM object to make it part of the raster image. For more information, see Merging REM Objects into an Image.
The Edit Mode menu appears when you select one or more REM objects and right-click. This menu provides a mixture of AutoCAD commands and REM commands.
When an AutoCAD command causes a REM object to become out of sync with the original image, AutoCAD Raster Design toolset erases the corresponding raster data from the source image. For example, you can define a region object and then move it. After you move the region object, the raster data is deleted from the original image. If you want to delete a REM object immediately after defining it, use the AutoCAD ERASE command.
For detailed instructions on using AutoCAD commands, see AutoCAD Help.
To access the full list of REM commands, from the Menu Browser, click Raster menuRaster Entity Manipulation. You can clear (delete) the REM objects, select all REM objects in the image, refine the selection that you used to create the entity, remove sub-components of the object, toggle background transparency or merge the object into a raster image.
If you have multiple REM objects selected, only those options that are valid for all of the objects are enabled. For example, if you select three REM objects and only two of them are in refine mode, the Refine Mode option is unavailable on the menu.
