I have what should be a very simple problem, but I cannot work out how to do it.
Basically, if I create a sphere (NURBS) and intersect it through the middle with a vertical plane and trim out half of it.
I then duplicate it with a -1 scale factor for the x to produce the other half. Now, I wish to attach these two hemispheres together, but whenever I select both of them and click attach it doesn't do it. I have tried reversing the surface directions but to no avail.

And after calming me down with some orange slices and some fetal spooning,
E.T. revealed to me his singular purpose.
Here is the file. I need these two hemispheres to be attached together into one surface. ( i know in this simple case this could be done by creating a sphere).
