Controls whether grips are automatically made hot when subobjects are selected.
When grips are selected, they change color and are made hot, which means that they can be used to modify the associated object or subobject. This setting is stored as a bitcode using the sum of the following values:
| 0 | Grips are NOT made hot when subobjects are selected. |
| 1 | Grips for the attributes of blocks, and the grips for the faces, edges, vertices, and controls points of solids, meshes, or NURBS surfaces are made hot when subobjects are selected. |
| 2 | Grips for polyline segments are made hot when these subobjects are selected. |
Setting this system variable to 1 is especially helpful for quickly modifying groups of faces, edges, and vertices on mesh objects.
