Compound curves on a curved surface

working on a butterfly sculpture and I’m looking to make a compound curve to make a structural grid.

shown here.
how can i get this type of compound curve on a complex surface like this butterfly wing?

Here’s one way to do it in Grasshopper: (22.1 KB)


Thanks Martin, this is a huge help.

i got the form to match my desired shape. now the next step is getting the intercepting points on each line?

i tried curve curve intersect but its only given me the end points not the crossing points

Thanks, still very new to this program so this was a huge help!!

Please take a look at the Modelab Grasshopper Primer, it’s a good resource.
