Hi Jeffrey,

We have this documentation about importing models: https://aximmetry.com/learn/tutorials/a-complete-studio-scene/complete-studio-scene-02-importing-the-model/ 

There is no option in Aximmetry to recalculate the normal face, you would want to do that in a modeling program like Blender.
Alternatively, you can use the Two Sided option in the model's mesh to show both faces. We don't recommend using models with this setting, however:

Also, make sure your compound has lights and a camera to see the model. We have a simple scene compound at [Common]:Compounds\Scene\Default_3D_Scene.xcomp with a minimal environment to see and test a model.

Warmest regards,
