In GeoDict, each GAD object has an index number. This numbers can be accessed with the help of the Create GAD Index Image command. This command creates a 3D volume field, where each voxel contains a 32 bit unsigned integer value describing the index of the object that this voxel belongs to.

This command requires no input parameters, so there are no parameters to be set.

When the command is run, no (result) files are created. The created index image is available in GeoDict as a volume field named GADIndex.g32. By a right click on the GADIndex.g32 line, the context menu allows to save the index image as .g32 file.

An index image can be visualized as other volume fields. The image below shows the index number field with small index numbers in blue and high index numbers in red.
