Capping (3 edge surfaces) out of a triangular network of lines

Hi everybody,

I made a short GH definition to get 3 edge surfaces out of a triangular network of lines.

My problem is that I don't know how to automatically iterate the process to get 100% of surfaces at the same time.

Any suggestions?

 

THANK YOU !!!

 

Matteo C.

 

 

by the way:

I know that sometimes my definition produces duplicate surfaces, but cleaning after baking into Rhino isn't a trouble.

My approach would be to use the Delaunay Mesh Component to get the faces to work with.

Hi Danny,

your solution is smart and "elegant" but it doesn't work properly with complex geometries.

See my example.

Hi Matteo,

If a plugin solution is acceptable, StructDrawRhino has some curve network traversal routines.  Can create a mesh or planar faces as desired.

Installation instructions are at http://www.geometrygym.com/installing  I'm happy to advise further.

You could remove faces that don't meet your criteria with the cull pattern component.

Hi Danny,

I already know your plugin, but I'm struggling to find a solution that's 100% made with standard GH components.

Hi Matteo,

That's why I posted, I think you're going to find it really difficult to do with native grasshopper components.  The iterative traversal doesn't lend itself easily to a native solution from my experience.  Best of luck with finding a solution, I wish I could help more.

Hi Danny,

it seems that sometimes most of surfaces don't meet this criteria! Furthermore empty cells must be filled one by one in Rhino.

I see the problem now.

Try this method with your example.

Scratch that it doesn't work in 3D

Just as a matter of completeness. I've overcome the 3D issue with this next version. But it won't work for cases where the you have a sphere etc as it projects to a plane.

Hm...your previous release was better.

I've improved my definition...now with autobake (from LunchBox tools) it's a little bit easier to manage hundred of panels.

If I could only manage a "timer" for automatical number generation (from 0 to X)..... in a couple of minutes my 3D frame would be completely meshed...while I'm drinking coffee !!!

I've just noticed a little bug...now it works definitely better!
