NX Parts are shading all black on this machine

Shaded parts are displayed as all black on this machine

User should first try to set the following:

Menu-> Preferences-> Visualization-> Rendering-> Graphics-> enable "Backface Culling"

Sometimes sheet bodies that are brought into NX via a translator may have their surface normal pointing in the opposite direction that is required to render them in shaded mode. Solid bodies that are an enclosed volume always have their surface normals pointing away from the body.
