Grasshopper
Meshes join problem
Hi all,
Dont know whats going on here exactly but i cant join this two meshes. The idea is later export as one single mesh into ecotect. In the definition i used giulios piacentinos definition for variable diagrid. ( the model i am using is just an exampletoroid)
Evertytime i try to join them, the mesh that completes the big one dissapears!
Attached the files in gh 07 and r4
Cheers!!

an important property of meshes is the orientation of the face, also sometimes simply referred to as "direction of normals". Faces have direction implied by the right-hand rule, therefore points need to be specified counterclockwise seen from outside, or frontally for open meshes.
So, your definition was almost right - I just modified the order of the points in the Surface from Points component and it started showing the mesh (please notice that the mesh was already there and that Grasshopper's own "Join Meshes", recently introduced, also unifies the mesh normals, but does not weld vertices).
I hope this is helpful,
- Giulio

PS: one could also modify the script to add the remaining case of a surface that is closed or periodic in both U and V directions (it's the last remaining case in single-surface NURBS topology).
