If this is for RAM Connection Standalone, the user can create one joint and assign to this joint all forces from all joints. In this manner the resulting connection will be the critical one. This procedure is done automatically in RAM Connection when it is integrated with RAM Elements. We sent all joints forces to a single joint design a connection that stands all forces and then assign the connection to all joints considered. Currently, if an user creates several joints in RAM Connection, the only way to select the critical would be visually checking what joint has the larger strength ratio.
