I'm having a bit of a problem with an imported OBJ model.
For some reason, the model has all of the exterior surfaces transparent, and all of the interior surfaces 'visible'.

I can't find any options to fix this in MED. Can someone point me in the right direction?

-Select all wrong oriented faces
-Look at the toolbar for the "flip normals" icon / button
-Click on it

Thank you. That's done the trick.
