mo/geometry** /cmo_name/geometry_name Associate the geometry named geometry_name with the mesh object named cmo_name. The value of the mesh object attribute geom_name will be set to geometry_name. All geometry information will be updated to the geometry information of geometry_name. This includes number of surfaces, regions, material regions, current geometry name, and definitions of active surfaces, regions and material regions. cmo_name and geometry_name must have been previously created. See III. E for a discussion of geometry. The **cmo/constraintommand might also be required.
