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

[Mery MB]

Hi Peyman

That is an easy way and correct but some times it make problem as well. I
tried before..

Imaging that volume is the jaw of a linac. I have at lease two jaws so
their mothers cover each other as well so it cause a problem. when two
mother cover each other even if it made by air, particle do not see the
daughters and they continuer their path and do not interact with Jaws.....
So your method do not work for all condition.

By the way Thanks for your answer....
