Defining geometry problems in different directions

Dear FLUKA users and experts!
I want to define a cylindrical geometry in the direction of 45 degrees or 135 degrees. How should I define it.
As shown in the figure.

I hope to receive the answers from all experts



You can achieve that using the ROT-DEFI instruction.
Have a look at the advanced geometry lecture from the last Fluka course to understand how it works.
