Gmsh never translates between CAD kernels: so if you build your model with the
built-in kernel, you won't be able to "export" it as as an OpenCASCADE model.
What you could do is to add "SetFactory("OpenCASCADE")" at the beginning of
your old script, and see if your geometry can get generated directly as an
OpenCASCADE model. (You might have to change a few things.) Then you could
export as .brep or .step.
