Gmsh's internal small CAS engine does not compute boolean operations; you'll need to either create the geometry directly (computing the intersections yourself), or use a CAD modeler (e.g. Freecad) to create the geometry and export e.g. in STEP.

We are working toward integrating "real" CAD creation routines in Gmsh, but it's not ready yet for general use.
