This realization type is used for modeling roll hemmings, where the outer shell is bent around the inner shell. The inner shell is connected to the outer shell on one side with simple hexa adhesive, and the other side is connected with RBE2 elements. A definable orientation node decides which side the hexa adhesive should be used. This line realization type is capable of connecting three layers that contains two components.
