Move 1 geometry to all hexagonal centre points

Hi everyone!

For 2 weeks I am working with Rhino grasshopper for my master thesis (I have to create a heat exchanger for additive manufacturing). I watched many tutorials to learn to work with grasshopper. Hopefully, you can help me to go on with my geometry. Attached you see the first steps tp build a honeycomb structre.

Question 1:

How can I move the brep or geometry along the centre of the hexagon-structure?

Question 2:

How can I transform a line into a spline. The spline should be formable, for example with graph mapper?! I ask this because I would like to create the inner structure of a honeycomb in spline so that the surface is bigger.

Thank you in advance for help!!

Greats,

Carina
