■ Backface - by default, only the front face of every polygon is drawn in
Autodesk Navisworks. Sometimes, during the conversion process the front
and back face of polygons get mixed, in which case, you need to adjust
the Backface option.
■ Near and Far Clipping Planes (frustum culling) - objects closer to the
camera than the near clipping plane or beyond the far clipping plane are
not drawn. You can let Autodesk Navisworks automatically constrain the
location of the clipping planes, or you can constrain their location
manually.
NOTE Backface and Clipping Planes are not used in a 2D workspace.
