Ruled surface In Sphere problem in duplicated volume
First of all, I am grateful to the developers for their great work. It is much appreciated.
Creating a sphere (or a segment of sphere) and using ruled surface with "In Sphere" gives a proper sphere which can be meshed with high resolution without much trouble. However when I create a volume of this sphere and try to create a symmetric duplicate ("Elementary entities">"Symmetry">"Duplicate volume") and move it somewhere else these new ruled surfaces are corrupted.
I have been using Gmsh version 2.10.1 on a Ubuntu 16.04 64b machine.
