Local axis of a node

[nastranuser123]

I have seen that some softwares have the concept of local axis of node.

I have never been able to really understand what is meant by lcoal axis of a node.

Can anyone provide insight/simple example.

You mean axes? Sometimes it's used to determine the directions of displacement constraints and the DOFs used in MPCs.
