The Color Mask toolbox provides tools to add color indices to a mask, to subtract indices from a mask, or to open the Color Mask dialog box.

The Color Mask tools and functions are not available for two-color images.

It is now possible to edit 3D oriented rasters with the Bentley Descartes editing tools. All of the editing tools now have a "Work in Image Plane" toggle to allow performing all editing operations as if the MicroStation coordinate system origin was moved to the rasteŕs origin and the axes are rotated as the raster is oriented. Multiple image selection is supported for the Add to Mask and the Remove from Mask tools. When performing the operation, the shape is projected in the direction of the active view accounting for perspective.
