Subtracting an assembly from a relief

Use the Subtract Assembly tool to subtract a mesh of the root Assembly, and all of its associated assemblies and meshes that are visible in the Project Tree, from the active relief layer. The top of the mesh is subtracted from the active relief layer.

To subtract the root Assembly and all of its associated visible assemblies and meshes in the Project Tree from the active relief layer:

1. Ensure the model containing the composite relief from which you want to subtract the root Assembly and all of its associated items in the Project Tree is open.
2. In the Project Tree, ensure the root Assembly and all of its associated items that you want to subtract from the composite relief is visible.
3. In the Project Tree, select the relief layer from which you want to subtract a mesh of the root Assembly and all of its associated items in the Project.
4. Ensure the selected relief layer is visible.
5. In the Project Tree, select the root Assembly. The Assembly panel is displayed below the splitter bar.
   Note: In the Project Tree, your previously selected relief layer is still active; indicated by its names being displayed in bold text.
6. In the Tools area of the Assembly panel, click the Subtract Assembly button. A mesh of the root Assembly is subtracted from the active relief layer.
