Roles

In RS3, geometry entities can have the following three types of roles:

• Construction: These entities will not be included in the External volume or be meshed. The role is helpful for excluding entities from your analysis or for options like Set SSR Area that do not require selecting meshed geometry.
• Excavation: These entities can be part of the External volume that is meshed and helps distinguish volumes that you will remove material in some stage.
• Geology: These entities can be part of the External volume that is meshed and helps distinguishes volumes that will not be removed at any stage.

They can all be modified or used to modify other geometry entities with some distinctions (see Geometry section for more details on modifying geometry). The entities can be sorted by roles in the Visibility Pane in the Roles tab.
