title: How to change geometry size
body: <p>I use gmsh in order to create a mesh of complex 3D geometry. From mesh file i can obtain surface elements to create a skin. How can I change coordinates of the skin in oder to make it smaller? Distance between points of the initial and changed surfaces should be the same for every point.

  Thanks.</p>
