[BUG?] - openmc csg-to-cad unit of measure issue

[SteSeg]

Not sure this a bug or a feature request. Anyways, I am trying to translate a csg geometry from an openmc xml file to a cad geometry with geouned. Apparently, openmc default unit of measure is cm while geouned defaults to mm. So I get a cad that is 10 times smaller than the csg model. I believe this should be fixed or a scaling factor/choice of the unit of measure should be implemented.

Expected behavior

Maintain the same dimensions/unit of measure.

Please complete the following information):

• OS: Linux
• GEOUNED version 1.3.0
• Python version 3.11

Hi Stefano,

The units of the solids are maintained during the conversion. I checked with a simple mcnp input and my 10cm cube was displayed as a 100mm cube with FreeCAD.
Perhaps it happens only with and OpenMC xml model? I will check .
