Junction is a sheet metal feature where two adjoining flanges are met, but not connected.
The junction has two types of connection: flanges or symmetric.
The type can be switched by using Quad or in the properties of the mechanical browser.
All bends can be changed to a junction or deleted.
The junction gap is controlled by the value in the properties section of the mechanical browser. It can be changed individually for each junction feature or for the whole model.
Junctions can be created in case of curved edges either.
