Blender Flip Normals To Outside
For the first the tuts should read hit m to mirror flip normals outside join and remove doubles.
Blender flip normals to outside. To access the option and or correct an inside out or inverted face first select the errant mesh element in edit mode 1 using vertex edge or face and from the mesh menu upper left click normals 2 then flip 3 from the options that appear mesh normals flip. For blender 2 8 users the command has changed a little bit. To manually flip a normal first select your desired faces. Ctrl n and shift ctrl n these tools will recalculate the normals of selected faces so that they point outside respectively inside the volume that the face belongs to.
The highlighted inverted face s will immediately invert based on their current orientation. Instead of recalculate press flip direction shortcut. The volume does not need to be closed. The mesh is low poly closed concave and manifold.
Alternatively use alt n to access the normals context menu then select flip. Ctrl n and shift ctrl n these tools will recalculate the normals of selected faces so that they point outside respectively inside the volume that the face belongs to. Shift n to recalculate the normals. Inside and outside are determined by the angles with adjacent faces.

Normals recalculate outside appears to flips the normal alternating between inside and outside rather than always recalculate them outside.
