[Gmsh] Copy

[dolfyn]

Dear all,

Suppose one has a 'blocking' (nodes, lines, transfinite lines and 
(recombined) plane surfaces)... something like:

  +-----+----+
  |     |    |
..+-----+----+.... (x axis)

(it's a bit more complex) when this is meshed (2D) one gets a nice 
quad mesh. Now I would like to save time and effort and copy/mirror 
this, say, using the x-axis.

If one hits 2D meshing then the new 'blocking' has obviously lost 
the transfinite/recombined settings.

Does anybody has examples of the 'Dilate' (and 'Duplicata' 
commands)? Geometrical entities are copied but not the attributes.

Next step was to extrude the model; the positive y-part and then 
copy/mirror the 3D (hexahedral) mesh and hopefully also 
the 'physical volumes and surfaces'.

Is this possible?

Thanks in advance!

Henk
