One thing that makes corridors so powerful is their ability to interact with other objects in the drawing. Corridors are able to morph themselves into different shapes and sizes in order to respond to existing features or components of newly designed features. This is made possible through the use of special subassemblies that can be stretched, twisted, and reconfigured as they progress along the corridor. What makes these subassemblies special is that they utilize corridor targets.
There are three types of targets that can be applied to a corridor:
surface targets,
width or offset targets, and
slope or elevation targets.
