Alright, I scaled the model in Blender by "normals" or so it says, and then exported back to MED as an fbx. When I imported it back into MED, I set the fbx scale to 5.0 and that seems to be a decent size, however it seems like it only scaled globally and not by normals. The shortcuts provided by @Kartoffel don't seem to work. "Alt+S" suddenly makes the model extremely large and the camera cant render the entire thing, and "w" brings up a secondary menu (with the entire object selected) with no option to flip the normals.
I apologize for seemingly being a pain the butt. Something so simple, and I can't figure it out
