You can combine reliefs using Boolean operation types with 3D Relief, Puff and Swept volumes and shape libraries. As each relief operation is created in the Operation the operation tree, these operation shapes will be combined with the existing project workspace shape using the selected Boolean operation. These operation types are explained below with the help of examples. The examples below show how 2 shape primitives can produce different shapes depending on the Boolean operations chosen.
 Operation Types, Primitive A |
 Operation Types, Primitive B |
This operation adds the generated shape, along the Z axis, to the existing Project Workspace as shown below.  Operation Types, ADD |
This operation subtracts, along the Z axis, the generated shape to the existing Project Workspace as shown below.  Operation Types, SUBTRACT |
This operation selects in the Z axis, the maximum value of either of the two primitives to create the resultant shape.  Operation Types, UNITE HIGH |
This operation selects in the Z axis, the minimum value of either of the two primitives to create the resultant shape.  Operation Types, UNITE LOW |
This operation selects only the volume that is common to both shapes and then selects the maximum value along the Z axis in this intersected volume.  Operation Types,INTERSECT HIGH |
This operation selects only the volume that is common to both shapes and then selects the minimum value along the Z axis in this intersected volume.  Operation Types, INTERSECT LOW |
