[Gmsh] Double surfaces after STEP import

I have not done FEM calculations for some time (a year or so). The last
time I did them (using gmsh and Elmer), I had the problem that in
geometries imported as STEP files (generated by Solidworks), adjacent
bodies have their own external surface, resulting in double surfaces at
the interfaces. When I use the mesh generated by gmsh in a FEM
calculation (I use Elmer), I get no thermal and electrical connection
because the body meshes are not connected at the interface. There have
been attempts to clean up double surfaces in gmsh, but I don't know if
they have come to a success. Could someone of the developpers update me
on this point?

Thank you!
