Beam's local referring system

[LcnGnd]

I'm using PyNiteFEA for my master's degree thesis. Using PyNiteFEA I think that a way to oriented y and z local axis si needed. I have to control how local system is oriented becasue in a complicated 3D model could be difficult understand all local referring systems that are defined by PyNite.
My idea is to use auxiliar points. It is possible to implement in PyNiteFEA?

Have a look at the code in Member3D.py for the member's transformation matrix, T. You'd have to reformulate the transformation matrix to account for a rotation about the member's local x-axis. In other words, the local z-axis direction cosines would need to change. You could then use the cross-product of the local z-axis with the local x-axis to derive the local y-axis.

Please use PyNite with caution. It's still a very young project. It still has a lot of limitations/assumptions built into it, and as you've seen, I'm still finding bugs here and there.
