[Gmsh] Defining Mesh

Hello,
In this picture the top is the original mesh of the scalpel. In the bottom
I defined some compound surfaces. The mesh changed but the problem is that
even in the one compound surface the mesh goes from point to point and is
smaller in the areas where there used to be a smaller surface. I would like
to be able to have a uniform mesh across surfaces.  Does this make the
problem clear?  Thanks for your help.
