Geometry deform

Hi, I 'm using ubuntu 21.O4. I updated the latest version of fluka and flair. I want to create a rectangular box but the 3D version of the shape looks like a triangular prism not a rectangle. I attached .inp and .flair. Could you help me?

Dear @demirukiye,
You need to move the viewport that is cutting your box. Have a look at the slides about the geometry editor to find out how it works.
