Control Rotation of families

I have been trying to place 3D model text families on the face of the walls but some of them are inverted and have no idea how can i control the Rotation of these familes.
Any Suggestions?

You tried with 2nsd item from sublist in “Principle Directions at parameter” Node.

Now try it with 1st Item from it!

Change Code Block Value to Zero(0) for “Get Item at index”

Assuming you always want them pointing up, you could use a single Vector.ZAxis node to orient them.
