When I recalculate normals all the faces flip direction.

Why is this happening?

How can I avoid this and keep the faces facing the direction I want to, even if I recalculate again?

    $\begingroup$ There are various reason why this happens, it could be caused by overlapping vertices or edges, scaling issues, export and import issues, none manifold faces ... etc. $\endgroup$ – hawkenfox Jan 30 '16 at 20:53
  • $\begingroup$ I'm curious why you have so many densely packed edges in one area... looks like there may be a topology issue here that should be addressed first. $\endgroup$ – Mentalist Jan 31 '16 at 1:46

    $\begingroup$ Try Shift Ctrl N (Recalculate Inside) instead of Ctrl N (Recalculate Outside). Blender determines what is inside and what is outside base on the mesh structure. $\endgroup$ – user2859 Jan 31 '16 at 12:18
