To Activate Geometry
1. Select a body or quilt node, a sub-node of a compound node, or surface subset of a component node from the Geometry and Topology Structure (GTS) Tree that you want to activate.
2. Click 
Activation > Activate on the Structure tab or right-click and click Activate. The selected node or subset of the node is activated. Active nodes are identified by the icon, 
, on the GTS Tree. Only one node can be active.

Only one node can be active. | • You can activate any node on a GTS Tree except for datum or facet nodes. You can activate a top-level node, a sub-node of a compound node, or a set of surfaces. You cannot simultaneously activate the body or the quilts node and the surfaces within the top-level body or quilts node. The compound node is activated when you select one of its component nodes or a surface or a set of surfaces within a component node, but you cannot simultaneously activate the compound node, one of its component nodes, and the surfaces within a component node. • When you activate a node on the GTS Tree, all connections between the surfaces of the node and the surrounding geometry are temporarily suspended and are automatically restored, if possible, when the node is deactivated. This is different from detaching a surface. When you detach a surface, the two-sided edges become pairs of one-sided edges permanently, unless otherwise manually manipulated to create a connection node and restore the two-sided edges. This is very useful for modifying geometry of sub-nodes of merge operations. • When you activate a surface subset of a component node, the connections between the activated surfaces and inactivate surfaces of the component are not removed. This allows the Repair tool to close gaps and repair tangency between and activated surfaces and the rest of the component. The Repair tool modifies the parameterization or boundaries or both of the only active surfaces. The Repair Tool may change neither the parameterization nor boundaries of surfaces that are not active. • When a node is active, you can reference any geometry in the model but cannot modify any geometry that is dependent. The geometry that defines the tree branch of a GTS Tree from the top-level node to the active node is called dependent geometry. • If a node on the GTS Tree is active and you activate a different node, the currently active node is deactivated and its corresponding connections restored, and the new node is activated and its connections are removed. |
