Hexagonal grid to meshes

Hi,

Does anyone know how to convert a hexagonal grid into a mesh?

I have tried using construct mesh and input the vertices of the grid but the component by default creates quad faces. I've created a multi-line data panel with the face I need but the construct mesh component reads it as a text.

I have also tried connecting the vertices with a polyline but I couldn't convert the polyline into a face.

Finally I tried using mesh from points but I get an error saying U and V count insufficient (regardless of the numbers I input).

Any help on this topic would be much appreciated. Thanks!

Hello Irina,

I don't really understand what you want to do. Do you want mesh lines ?? Or a mesh with hexagonal faces ?? Because a mesh with hexa faces is not easy(for me) but you can try the dualgraph of weaverbird to transform a triangular mesh into a hexa grid or you can trick the thing and use the center point of each cell to have a network of 6 triangular faces per cell. Here's an example. I think it will be better if you explain a little more of what you want to achieve with this.

Hello

rhino works with meshes that have triangular or quad meshes. so you will have inner esdges for the hexagon. by default there will be one in the middle. you can also use starling plugin that has two components.

slstarmesh which will output meshes with triangular faces form the center of the hexagon and slsource mesh which outputs meshes with triangles originating from one of the vertices of the hexagon.

turtle plugin enables ngon meshes.

Haha !! Thanks Alex !! I didn't konw the mesh and Turtle components can be used like that ! Nice

yes its nice. but many components after turtle revert the mesh to triangular or quad (mainnly those that operate on faces). others dont (like weaverbirds frame component)
