Frequently complex connections between components can be idealized with the creative use of rigid body elements (RBEs). An analyst can "zip" together different components using node-to-node RBEs where each element only has one dependent node and one independent node. In the case of non-zero length RBEs, a different selection of dependent and independent nodes will result in different results.
Manually "flipping" these elements (swapping the independent and dependent nodes) is a time consuming and error prone task. This API will automate the process and make element selection easier for the user by automatically excluding non-RBEs, RBE2s with multiple dependent nodes and RBE3s with multiple independent nodes.
