i need some Help.
ich have 3 Csys.
The Main Csys. A Csys (2) in the Main Csys. And a Csys(3) in the Csys(2) which is in the Main Csys.
And now i want the X, Y, Z Coordinate of the Csys(3) dependent on the Csys(2).
I tried to use Location but it gives me always the Coordinates dependent on the Main Csys.
Thanks for your Help !!
The API function (almost) always return coordinates in the absolute coordinate system. You can report coordinates in a different coordinate system with the help of the .MapPoint method (wrapper for the UF_CSYS_map_point function).
It can be done by developing a 4 x 4 matrix. It involves using i,j,k as unit vector of the "new" coordinate system, i,j,k as unit vectors of the "old" coordinate system and origins of the "new" and "old" coordinate systems. I suggest you look this up in a text book. One reference is
