put a geometrical object above another

Is there some way to colour the surface inside the circular curve with a white colour so that the line going through the small circle or ANY other curves going through the circle will not be shown?

Thank you for you tipps and advice in advance.

For example, could I make out of this small circle a 3d volume like a sphere that would help me to see in the XY-Plane only the black circular curve with a white space inside it regardless whatever curves are passing through this circular curve? ...

I have been trying the component shatter and the component extrude point ... it's getting two complicated and I wonder if there is component or a technic, that is in gh for something like this ...

Thank you again ...

EDIT:

Not working with a sphere ...

I'm trying to get something like this with nonlinear curves passing through my circular curve ...

Does the new Grasshopper has new point symbols? ... Where to start, if I want to programm a point shape with lets say VB? ... It's an important job to get this done somehow ... So again thanks for the advice ...
