Metal 3D has incorporated the possibility to define Ties between nodes. The ties between the nodes are used to indicate that two or more nodes have the same displacements for all the loadcases. This displacement can be in one, two or three directions in accordance with the X, Y and Z global axes. The number corresponding to each group of nodes whose displacements have been tied is displayed on screen.
Bear in mind that for two or more nodes to have the same displacement, an element or construction arrangement must be present in the structure that will effectively materialise the equal displacement hypothesis.
Ties cannot be assigned to nodes that form part of braced frames when the tied displacement has its projection on the plane of the braced frame.
