About the Cut Operation in IDD
You can select the items that you want to cut on the GTS Tree or in the graphics window. You can cut the following objects from the GTS Tree:
A single, base-level node except the one that contains the active node
A single, immediate sub node of a base-level or active Combined node
A subset of surfaces of one base-level or active Component node
Any combination of datums such as planes, axes, coordinate systems, and points, and 3D curves from anywhere on the GTS tree structure.
You cannot explicitly cut items that you cannot select directly on the GTS Tree. Therefore, you cannot cut UV-curves or individual surfaces of procedure nodes. However, if you cut a surface that has UV-curves defined on it, its curves are cut along with it.
You cannot cut a suppressed connection node, merge or combine, or any dependent geometry nodes resulting from suppressed connections. A suppressed connection node is a dependent node on a Merge or Combine node that includes currently active node.
When node or nodes are cut, they are placed on the clipboard. The nodes are removed from the GTS tree, and their geometry is removed from display. For cut surfaces, any two-sided edge connections they share with uncut geometry are split into one-sided edge pairs.
