On the contrary, it assumes that the object is at the origin.

Actually, it would be easier to model it at the origin, turn it using
the macro, and then translate it to where you want it.

But if you've already modeled it to turn around some other point, then
use some other transforms before and after:

object { MyGun
  translate -GunLocation
  PointAlong(z,<-1,1,14>,y)
  translate GunLocation
}

This moves the object to the origin, rotates it, and then moves it back.
This code assumes the gun is originally modelled pointing in the +z
direction.

BTW, the macro I gave earlier turns the object, and raises it or lowers
it as well (ie, give both yaw and pitch).  If you want just yaw or just
pitch, let me know and I'll explain how to call the macro for that.

John
