Morphing Junctions
Occasionally, you may want to change a junction's type in your model. You can do this by morphing the old junction into a new one.
If you hold down the CTRL key, select a junction from the Toolbox, and then drop it onto an existing Workspace junction, the old junction will morph into the new one. The junction type will change to the new junction type, and data that can be kept will be copied into the new junction.
