Hi Brian, the way MoI's NURBS geometry works is very different from 3D Coat.

It is difficult for MoI to have control points turn on for primitives that are made up of trimmed surfaces, rather than all untrimmed surfaces.

You can actually turn them on if you want by using Edit/Separate to break an object into individual surfaces - you can always turn on points for just a single surface that is all by itself.

But by default MoI does not turn them on for joined trimmed surfaces since it would be too easy to pull things apart and end up with gaps between what used to be a shared edge.

For some more information and illustrations, please see this FAQ entry:

FAQ: Why does show points work for some objects but not others

It's easier to have points on all the time for a polygon-based modeling system than a NURBS-based one, due to the system of an "underlying surface with trim curves", that is used with NURBS. But it is also that same system that makes booleans work much better with NURBS as well.

If you want to work with surface points a lot, you may want to use a polygon modeling system for that particular kind of work rather than MoI.
