Multi-level tree of components
Multi-level tree of components

This example demonstrates the most performance efficient way to select a component on any level of the assembly by its full name.

Name of the component is defined as a path where each level is separated by / symbol. Component instance id is specified with a - symbol (e.g. FirstLevelComp-1/SecondLevelComp-2/TargetComp-1)

Component name can be found in the following dialog:

Component name in properties dialog
Component name in properties dialog

Refer Get Component By Name example for macro to retrieve the pointer to the component without the selection.
