For some things it’s easier just to lay out curves and sweep the surfaces, at least for me. While Modo doesn’t have NURBs, it does allow you to do some of the same kind of modeling using curves and Patch Curves tools. This is where you find the Patch Curves tool.

I’d lay out four curves, snap the vertices to each other, then try to run the Patch. No such luck. You can extend the curves on the ends for some cool effects, but no surface like you’d get using a Boundary or Square in Alias.

The Fix:
