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.
