Hi Guys,

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 !!

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

This 4x4 matrix can be obtained using NXOpen.UF.UFMtx4.CsysToCsys():
