Hi Booleano,

re:
> Why do the dots appear on object "A" but not on "B"?

It's because all the faces on object A are naturally trimmed (trim boundaries are same as underlying surface boundary) while object B has some faces that trim away areas of the underlying surface.

There is info on this in the FAQ, see FAQ #4, "Why does show points work for some objects but not others?"

This is one of the various reasons why it is better to use a subd modeling program to make this type of model, MOI is not the right tool for doing this.
