Transfinite using progression is not conserve by Symmetry
Sometime using a symmetry reverse the direction of
Using Progression for a transfinite curve. For example, if we construct a square annulus and we want a geometrical refinement toward the outer boundary.
I first construct the part (1) in the fist quadrant then I do a symmetry with respect to y-axis to get part (5), everything works fine. Next, I do the symmetry with respect to the x-axis to get part (15) and (10) but the direction of the transfinite vertical curve has been reverse, see the image.
Here the file that produce this behavior test.geo. I am using GMSH version
