Dear Yuri,
One last thing!
I think there is no "one click" method to rotate the whole setup
(source, geometry, tally) on desired angle. It can be done in case of a
simple test geometry of yours.
In general you have to set parameters of each component separately. In
attachment the rotation works for angles from 0 up to 90 degrees.
Best regards,
Mikhail
