About Performing Various Tasks on GTS Tree Nodes
You can perform various operations on the nodes of the Geometry and Topology Structure Tree. The following options are available on the shortcut menu when you right-click a top-level body, quilt, or compound node:
• Activate—You can activate any node on the GTS Tree except a Datum node. Select a body or quilt node, a component sub-node, or a set of surfaces within a node on the GTS Tree. Right-click, and click Activate on the shortcut menu or click 
Activation > Activate on the Structure tab of Import DataDoctor. Though the display of the GTS Tree structure does not change, functionally the active node becomes the top-level node. All connections to the active node geometry, except the component surface subset that is activated, are removed. Active nodes are identified by 
on the GTS Tree.

Active nodes are identified by on the GTS Tree.You cannot simultaneously activate the body or the quilt node and the surfaces within the body or quilt 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. However, you cannot simultaneously activate the compound node, one of its component nodes, and the surfaces within a component node.
• Deactivate—You can deactivate an active node or the active surfaces of a node on the GTS Tree. To deactivate a node or a set of surfaces, right-click the node or surfaces, and click Deactivate or click Activation > 
Deactivate on the Structure tab. Deactivate is available regardless of whether objects exist in the selection bin or not; you do not have to select the active node or surfaces to deactivate them. When you deactivate an active node, Import DataDoctor restores all the connections that the node had before it was activated. You can also activate another node to deactivate the currently active node without explicitly deactivating it.

When you deactivate an active node, Import DataDoctor restores all the connections that the node had before it was activated. You can also activate another node to deactivate the currently active node without explicitly deactivating it.• Solid—You can control the solidification of quilts with this check box option. The Solid check box appears selected by default for body nodes, even when the solids in the body node are generated from non-solid quilts and is not selected for the quilt nodes, even when they represent closed quilts. If you select a body node and clear the selection of this check box, the body node changes to a quilt node and its generic system-assigned name changes from Body to Quilt. The quilt node subsequently reverts to a body node when the Solid check box is selected and the generic name changes from Quilt to Body.
• Detach—You can detach the surfaces of body and quilt nodes and the sub-nodes of compound nodes such as a component or combine node to repair or replace the surfaces and sub-nodes. To detach surfaces or the sub-node of a compound node, select the surfaces or the sub-node of a compound node, right-click, and click Detach on the shortcut menu or click Detach on the Structure tab. Alternatively, right-click in the graphics window and click Detach.
Detaching a set of surfaces or the sub-node of a compound node creates a top-level node named Quilt ####. The new quilt node contains the detached set of surfaces or the surfaces of the component or combine node. The Solid check box does not appear selected even if the detached surfaces belonged to body nodes. Detaching nodes containing surface geometry removes all connections to those surfaces. However, connections among the detached surfaces are maintained in the node.
 | You cannot detach nodes from component or combine nodes that are part of a merge node unless they have been explicitly activated. |
• Divide—You can divide the surfaces of body, quilt, and component nodes. To perform a divide operation, select a surface or surfaces of a top-level node or a component node in the graphics window or the GTS Tree, right-click, and click Divide on the shortcut menu or click 
Divide on the Structure tab. This results in the creation of a combine node that consists of a new component sub-node. The combine node may be the top-level node or a sub-node of a node. The Divide operation moves the the surfaces selected for the Divide into the new component sub-node. If you had selected a sub-node or a component node for the Divide operation, the surfaces of the sub-node is moved into the new component sub-node. If only a single surface is selected for the divide operation, the combine is between that surface and the original component.

If only a single surface is selected for the divide operation, the combine is between that surface and the original component.You can divide body nodes and sub-nodes. Dividing a node creates two component sub-nodes. The Solid option setting of the original body or sub-node is retained by the component sub-nodes.
• Combine—You can perform a combine operation on two or more nodes on the GTS Tree. To combine nodes, select two or more nodes on the GTS Tree, right-click, and click Combine on the shortcut menu or click 
Combine on the Structure tab. When you combine two or more nodes, IDD creates a combine node and the selected nodes become sub-nodes or component nodes of the combine node. If the nodes selected for the combine operation includes a body node, the resultant combine node retains the Solid option setting of the body node. However, when you select two body nodes to combine, a message prompts you that you cannot combine two body nodes. If you selected two body nodes, to combine these two nodes, you can right-click one of the body nodes and clear the selection of the Solid option check box so that this node changes to a quilt node.

If you selected two body nodes, to combine these two nodes, you can right-click one of the body nodes and clear the selection of the Solid option check box so that this node changes to a quilt node.| | You cannot combine merge nodes. |
• Merge—You can perform a merge operation on any two nodes that represent valid quilts. To perform a merge, select two top-level quilt nodes on the GTS Tree, right-click, and click Merge on the shortcut menu or click 
Merge on the Structure tab. When you merge two nodes, IDD creates a new top-level merge node and the selected nodes become sub-nodes of the merge node. The merged node retains the generic name of the target node of the merge task. Alternatively, it may take the system-assigned name, the name of the node as read from the source file, or the name assigned by the user after import.

The merged node retains the generic name of the target node of the merge task. Alternatively, it may take the system-assigned name, the name of the node as read from the source file, or the name assigned by the user after import.The sub-node of the Merge node that represents the original target node of the Merge operation retains the generic Component #### name. The target node also retains its Solid option setting even if the other node selected for the merge operation has a different Solid option setting. The node that is not the target retains its name, whether read from the source file, assigned by the user after import, or the generic Component ####.
• Collapse—You can perform a collapse operation on a combine or merge node that exists at any level of the GTS Tree. Select a combine or merge node that is a top-level node or a sub-node of a compound node on the GTS Tree, right-click, and click Collapse or click 
Collapse on the Structure tab. The combine or merge node is collapsed into a single component node. The Solid option setting of the collapsed node is retained by the resulting component node. If the collapsed node represents a quilt, its Solid check box does not appear selected.

If the collapsed node represents a quilt, its Solid check box does not appear selected.You cannot collapse compound body nodes. However, you can collapse the compound sub-nodes of body nodes such as the sub-nodes of Body nodes created by the combine, merge, divide, or convert operations. If the collapsed geometry contributes to bodies or quilts of the import feature, new nodes are not created. If the collapsed features represent all the geometry of a body, a new body node by the system-assigned generic name of Body #### or the explicitly assigned name, is added to the GTS Tree and its Solid check box is selected. If the collapsed features represent a quilt of the import feature, a new quilt node by the system-assigned generic name of Quilt #### or the explicitly assigned name, is added to the GTS Tree and its Solid check box is not selected. If the set of collapsed features represent one or more solid bodies or quilts, a single collapse operation creates multiple body and quilt nodes. Each body or quilt node has its individual Solid option set.
• Convert To Combine—You can convert a merge node to a combine node. To do so, select the merge node, right-click, and click Convert To Combine or click > on the Import DataDoctor tab. When you convert a merge node to a combine node, no geometric changes occur to the structure of the GTS Tree. The converted merge nodes maintain the same place on the GTS tree that they had prior to conversion. However, the quilts involved in the merge are permanently trimmed to their merged state. If the combine connection is deleted or temporarily disabled, the geometry of the node before the merge operation is not restored.
When you combine two or more nodes, the combined node inherits the name of the original target node of the combine operation. The target node retains its Solid option selection as is applicable even if the nodes combined have a different setting
• Exclude—You can exclude surfaces. When you exclude a node, the selected nodes are detached from the top-level nodes or the component sub-nodes and placed under exclude component node, and are hidden in the graphics window. The Exclude node is retained with the model even when you exit IDD. To exclude a surface, select the surface, right-click, and click Exclude on the shortcut menu or click > on the Import DataDoctor tab.
• Include—When you include an excluded surface, it is added to the tree as a new base node. To include an excluded surface, select the excluded surface in the Exclude node on the GTS Tree, right-click, and click Include on the shortcut menu or click > on the Import DataDoctor tab.
• Hide—You can hide any base level active node.or a datum node. Select one or more nodes on the GTS Tree to hide, right-click the nodes, and click Hide on the shortcut menu. Alternatively, click > > 
Hide. When you hide one or more nodes, the nodes are temporarily hidden in the graphics window. When you try to hide a sub-node, such as a component node, the top-level base node, such as body node is hidden.

When you try to hide a sub-node, such as a component node, the top-level base node, such as body node is hidden.• Unhide—You can perform an unhide operation on any of the hidden nodes on the GTS Tree. To unhide hidden nodes, select the hidden node or nodes on the GTS Tree, right-click, and click UnHide on the shortcut menu. Alternatively, click > > 
Show > Show or 
Unhide All. When you unhide one or more nodes, the nodes appear in the graphics window.
