    $\begingroup$ are you sure you added the right screenshots? I mean both show the object before any modifier has been applied. I can't tell the difference. $\endgroup$

  • $\begingroup$ @stacker the mirror and skin modifiers have been used but the two screenshots do look identical to me, just from different angles. I think by “applied” he means used, not actually applied. $\endgroup$

  • $\begingroup$ @PGmath Sorry you're right, when I say "applied" I want to say used. $\endgroup$

  • $\begingroup$ @stacker when you put "mirror" in the first one is supposed to get the 2nd picture but my shape does not change. $\endgroup$

  • $\begingroup$ The pictures appear to differ in the concave/convex respect of the beam that runs the center of the object $\endgroup$

This could be avoided using clipping in the mirror modifier.
