Facing and hand orientation explaination

[scottbaldy]

I have an Assembly instance with a beam member and several face based generic models which are all members of the assembly. I am trying to determine how the generic models are oriented on the beam (attachment face and rotation) not worried about coordinates just yet. Attached is a sketch of the beam and (3) plates. P1 and P2 are attached to the web face at opposite sides. Plate P3 is a face based plate but is not attached to this beam  However, it is part of the assembly. The sketches below the beam are of each plate family and how they were oriented when created (not sure if this matters for the hand and facing orientation).  (Just realized family sketch of P3 is rotated 180 about its local z-axis when placed in the model). Also, below is output of the assembly showing the Assembly basis, beam facing and hand orientation, and the generic model facing and hand orientation. I cant seem to figure out how the facing and hand orientations relate to their respective positioning.

Could someone please enlighten me or point me in the right direction? Thank you!

Assembly ID: 3951083
Assembly Name: 1-B1
Assembly X-Orientation: (1, 0, 0)
Assembly Y-Orientation: (0, 1, 0)
Assembly Z-Orientation: (0, 0, 1)

Members in the Assembly are:
W12X26
Facing Orientation: (0, 1, 0)
Hand Orientation: (1, 0, 0)

Plate - P1
Facing Orientation: (0, 0, 1)
Hand Orientation: (-1, 0, 0)

Plate - P2
Facing Orientation: (0, 0, -1)
Hand Orientation: (-1, 0, 0)

Plate - P3
Facing Orientation: (0, 0, -1)
Hand Orientation: (0, 1, 0)

This may not be an answer but I had to do something similar with doors and the only way to figure it out was to use revit look up and look at how the family is created, snoop it, and then that would give you a base line of how it is placed in the model, and then snoop that as well. 

The .rfa should give you a better idea of how it is set up though. It's been a while since I gave it a go.
