Newbie question: editing an object's edges

Hi all,
I'm discovering this revolutionary software that is MOI and as a real newbie in nurbs modelling, I'm struggling a little. I was wondering if it's in the nature of this type of modelling not to be able to manipulate an object's edges (see attachment) or is it just me who hasn't got the right workflow ??

I've search the forum, did find interesting posts but none concerning my present issue :)


Anyway congrats for this nice software!
