I am trying to find a Femap API call to get the local element coordinate system for 3D elements. Does one exist or should I get started writing my own. It seems like something that should exist somwhere within the ecosystem.
Any help much appreciated!
Regarding this post and your other one about solid laminates, have a look at what I posted a few years ago, the thread was called "Change normal orientation of brick solids elements", it might help.
I wrote an API dealing with brick orientation, you'll find the lines dealing with extracting the coordinate system of bricks. Regarding wedges and tetras I've never needed it so I've never coded it.
