A storey's placement chain reduced to a planar rigid motion in the model's world frame, in metres: world = R · storeyLocal + origin, with R the rotation whose first column is axisX.
world = R · storeyLocal + origin
R
axisX
The storey's local X axis in the world frame, unit length.
The storey origin in world-frame metres.
