Attempting to create a mesh with polysurface

Hi,

I was following a tutorial online. It asks to reference a polysurface drawn in rhino into a Brep component in GH, however, when I connect it to a Mesh Brep it doesn't break into triangles like shown on the tutorial.

I have attached a pic, could someone tell me where I went wrong please

In your picture I think you have the brep selected in gh , thus highlighting the UV surface divisions of the brep in yellow in rhino... You have options to change the resolution of the automated mesh aproximation of the brep... or you can use a component like triangulate in the mesh tab or similar as found in weaverbird.

How you interpret a brep into a mesh depends very much how the surfaces are set up before converting... often dividing an untrimmed surface to UV and then checking you have planar quads for meshing ..or triangulating and getting delaunay triangulated forms... will make an efficient usable mesh..

Hope that helps and isn't to cryptic yet.

Hi Roderick,

thanks for replying, I will continue experimenting with it thanks!
