If you wanna select only reversed faces, use Ctrl+Shift+Alt+M but in Edge select mode. It doesn't work in Face select mode, and if you use it in Vertex select mode, it will select too much.


I assume you want to clean up the wrong normals? Go into edit-mode, select everything (a), and press ctrl+n. This will recalculate the normals.

    $\begingroup$ Yes i want clean up the wrong normal. Ctrl+N don't work on this mesh. You can try with may .blend. I want select face that have reversed normals. $\endgroup$
