Hi Dirk,

Thanks for your post here!

To be honest, it’s a bit tough to diagnose what could be the issue without knowing some specific details about the decenters/tilts you’re using. Are the Coordinate Break surfaces co-located and imparting tilts/decenters that are not in the same direction, but still giving you identical RAID and RAGZ values? Are the Coordinate Breaks in different spatial positions?

For the second situation, I think we’d need to see your file first-hand to investigate further. I did try to define orthogonal tilts/decenters in two different configurations (one has decenter/tilt w.r.t. the X axis, the other Y):
 

Here, I see that the GBSP and GBSW values are retained in each configuration, though I did need to use the -W0 value to obtain X-direction results:

I did also try a third configuration where I imparted the same tilt/decenter, but about a diagonal axis rather than the X and Y ones. I received different results here, but I believe this is due to the X/Y results taking a different cross-section of the beam in Config 3 as compared to Configs 1 and 2:

Unless the issue you were experiencing is different from my thoughts here?

Let us know how these thoughts work for you or if we can take a look at your file for more investigation as needed. Thanks!
