[Gate-users] How to rotate a volume in two direction?

[Mery MB]

Dear John

NOt at all!!!!!!!!!!!!!!!!!

As you told the below lines are setting the minimum and the maximum angle
of the cylinder. But I want to rotate this cylinder around two axis with
two different angle. At first rotate around x axis for 90 degree and then
rotate it around z axis for 6 degree.
/gate/Jy6-31/geometry/setPhiStart         9 deg
/gate/Jy6-31/geometry/setDeltaPhi         360 deg



I tried to rotation simultaneously but it is not work properly at all!!!!
I tried the below lines :

/gate/Jy6-31/placement/setRotationAxis         1 0 0
/gate/Jy6-31/placement/setRotationAngle        90.0 deg
/gate/Jy6-31/placement/setRotationAxis         0 0 1
/gate/Jy6-31/placement/setRotationAngle        6.0 deg


or


/gate/ Jy6-31/placement/alignToY
/gate/Jy6-31/placement/setRotationAxis         0 0 1
/gate/Jy6-31/placement/setRotationAngle        6.0 deg


both of them do not work properly!!!!!!!!!!!!!!!!!

I will be thankful if someone can help me in this issue.

Best
Mery
