Hi Rogurt, can you please post the 3DM model file that you are talking about instead of only a screenshot? It is much easier for me to look at a 3DM file that I can actually zoom in on and look at from different angles, etc...
But it kind of sounds like you are trying to construct things in a "patch by patch" basis, which is not the optimal way that you should usually be trying to use with NURBS modeling.
Instead you want to be creating larger chunks of your model as single broad surfaces, and then some edges are introduced by cutting some of those extended pieces, rather than trying to build the entire final edge wireframe from the start and then patching that in one piece at a time.
See some of these previous discussions on this topic:
