If you have ever used the standard Spider API program provided with Femap install, then you might have a clue what this program can do. In this version, the API prompts you for the two regions that you want to connect and then allows you to automatically create a user-defined beam element having a user-specified material property between the two spiders. In one clean API operation, the spiders and beam element are created. This script then automates the creation of a bolted connection in one fell swoop. The program will even remember your prior settings for multiple operations. Very sweet...


Creates a NX Nastran RBE2 element with all six DOF locked. The program prompts user to pick nodes around a circle or region, calculates the centroid of the nodes that you have picked and then creates a new node at this centroid as the independent node for the RBE2 element.
