Using parametric solid with Gordon surfaces often fails to join surfaces

[Anthony-Gaudino]

I have been working on a part that requires complex shapes and have been trying to use gordon surfaces, but they often fail to join into a shell or solid, I had to use the surfaces from the Surface instead as these were more likely to work.

Here's one example that fails: join_gordon_surfaces.FCStd.zip

Gordon surfaces involve approximation, so tight enough joins are not guaranteed.
