Define a Set
You can create as many sets/groups as you want, and the same entity can exist in multiple sets. All component/part (only) set types that are created will be displayed in the entity list tree in the Entity Attributes panel and in the Results Browser (click the Sets drop-down menu to view the groups and their components).
- From the Create tools, select .
-
From the Set panel, click Add.
A set/group is added to the bottom of the Sets list.Note: By default, the newly added set is automatically labeled given a name and is assigned the entity type currently selected on the input collector.
-
With the new set highlighted, change the input collector to the type of entity
you want to add to the set.
When a different type of set (group) is selected from the Sets list, the entity type shown on the Selection input collector is updated to correspond with the new set type that was chosen. Conversely, if the input collector type is changed, the set type of the highlighted group will be converted to the new set type that was chosen. For example, if the input collector of a component group is switched from Components to Nodes, all the nodes of the original components become the entities of the set. The set type is automatically updated, based on the entity type that is selected using the Selection input collector.
- Select entities using the input collector or pick directly from the screen.
