In 2.7x I never used the “recalculate normals” tool because “make normals consistent” tool (mnc) was so much better. The difference between the two is (I think) that recalc would adjust all normals and sometimes flip them to wrong direction. Pretty awful as sometimes it randomly flipped different areas upside down when all I wanted to do was to get rid of one or two flipped faces on a mesh. Mnc I think always just flipped the minority of faces to match the majority. Mnc was great as it always got those right and I never had to recheck anything.
Where is make normals consistent in new blender? I can’t find it in the spacebar search menu? Has the tool been deleted or renamed into something else? I can’t seem to find anything about it anywhere. All I found was that ctrl-n keyboard shortcut was changed but nothing about the tool itself.
