[Gmsh] Rotate all

[Ruth V. Sabariego]

You can get arrays with all the point, line, surface or volume numbers :

allPoints[] = Point "*" ;
allLines[] = Line "*" ;
allSurfaces[] = Surface "*";
allVolumes[] = Volume "*";

and then rotate then (possibly with duplication):

Rotate {{0, 1, 0}, {0, 0, 0}, Pi/2} { Point{ allPoints[] } ; }
Rotate {{0, 1, 0}, {0, 0, 0}, Pi/2} { Duplicata { Point{ allPoints[] } ; } }


It is possible to do the operation directly on volumes or surfaces. 

Rotate {{0, 1, 0}, {0, 0, 0}, Pi/2} { Surface{ allSurfaces[] } ; }
Rotate {{0, 1, 0}, {0, 0, 0}, Pi/2} { Duplicata { Surface{ allSurfaces[] } ; } }

Pay attention to centers of circles or spheres, though...

Regards,
Ruth
