How to connect the pieces?

Hollo everyone, I am currently doing a nurbs project. But I got two problems need to be resovled.

1. As you can see in the picture A. I made the pieces by using "network" or "sweep" fuction. Just don't know how to connect the pieces seamlessly? ( picture A )

2. How to make curvy copies in proportion between two curvies? ( two yellow curies in picture B )

I know there are fuctions in Rhino can solve the problem. Just wondering are there same or similar functions in MOI?

Thanks.

Justin
