I need to create a mirrored version of my mesh. In edit mode I press M plus the axis. But the normals on the mirrored faces are flipped, so I have to select all faces and recalculate/flip the normals.

I want to eliminate the last step. Is there a way to make the mirror function keep the normal direction of the original faces?

  • $\begingroup$ @Millard is right, unless you use the mirror modifier, you can't do that. $\endgroup$ Jan 4, 2022 at 12:02

Using the mirror modifier is a good way to mirror an object and it solves your problem.
