The Connect feature can be used after the Share Topology feature to selectively share faces between two bodies of a multibody part. You will need to specify a tolerance and ANSYS DesignModeler will connect two faces into one face if the faces lie within the specified tolerance. The Face Connect feature requires that the two faces being connected belong to two different bodies of the same part. The T-Junction option is also available when using the Connect feature after Share Topology. By turning on this option, ANSYS DesignModeler will first split faces and edges where faces are coincident within tolerance and then perform the connect operation.
