I have a series of security camera components. Because of the designer's requirements, some are ceiling based and some are face based.
I am trying to figure out what way the element is pointing in plan. For the ceiling based ones, I can easily get the FacingOrientation and do some math to figure it out. For the face based components, when they are placed on a wall, or any other vertical surface, the FacingOrientation simply comes back as (0,0,1) which makes sense because it was rotated up from "the floor", in the family editor, to a vertical surface.
I think I need to get a line that is perpendicular to the host. I don't know if the host or hostface is the way to go, since I can't really figure out how to use the hostface.
I could probably make something that would give me a perpendicular line to a straight wall, but what if it's a reference plane, or what if it's the face of a generic model? I would like something a little more all encompassing.
