About the IDD Transform Tool
You can use the Transform tool to transform the following nodes on the GTS Tree:
A datum, a surface, a complex node, and so on
Sub nodes of complex nodes
However, you cannot transform the Datums Bin node, Exclude Bin node, or any sub node of the Exclude Bin node.
You can transform more than one node at the same time. Connections of complex nodes such as combine or merge nodes are maintained if possible after the transformation of sub nodes.
The Transform tool user interface has the Move and Placement tabs. You can use the Move tab to move the selected geometry and the Placement tab to place constraints to define the transformation.
You can use assembly type constraints to define the transformation of the selected node or nodes. However, these constraints are not parametric and are not retained if you select the same nodes again for transformation. These constraints cannot be reinforced as in surface alignment constraints. Avoiding constraints placement and only moving the selected geometry or nodes ia a simple and fast way to get the required transformation and the best method to use in IDD. There is no difference or advantage over fully or partially constraining a transformation as the constraints are not parametric. Ensure that you enough constraints to get the desired transformation.
When you transform nodes using the Transform tool, you can embed datums in complex nodes and use these datums as component references for the transformation constraints. These datum references are transformed along with the surface geometry of the nodes. Any datum that is not embedded in the transformed nodes or any surfaces that are not associated with the transformed nodes are considered as assembly references.
