Hi,  
I would like to post-process some 3D calculations of an almost Axisymetrical geometry.  
I like to make a cylinder slice of the domain and to transform this cylinder slice into a 2D develop view of the cylinder.

Is it possible to acheive this with paraview or shall I write some specific plugin?

I also run into trouble while trying to get some OrOz slice (plane slice centered at the Origin and with of normal at a given angle). I didn’t manage to position the camera properly.  
I’ve tried to force the camera position in a python script like that:

```auto
viewUp=(0, 1, 0),
viewAngle=30,
roll=angle,
elevation=270,

```

 ![elasticity.displacement-deformed-OrOz-theta=0deg](https://discourse.paraview.org/uploads/default/original/2X/f/fd3986006cb68e8cb7a8497de575a77ec6b74978.png)  
 ![elasticity.displacement-deformed-OrOz-theta=45deg](https://discourse.paraview.org/uploads/default/original/2X/1/16dbda0358c8504b27737783f40d7052920fe739.png)

When angle = 0, it works but the reference frame seems wrong. The Oz axis should be where the Oy is plotted.  
When angle = 45, I cannot see the plane. The reference frame seems also to be wrong.  
How shall I position the camera to see the plane for any angle?

Best
