Hello,
I am trying to draw a warped surface - hyperbolic paraboloid - in Grasshopper (see below). The surface would be best constructed from U and V coordinates (angle between them is 60 degrees, so they are not orthogonal).
Is it possible to do that in Grasshopper? It would be great to define the coordinates as U and V instead of the orthogonal coordinates.
These are photos of part I am trying to draw:

Thanks a lot in advance!
Thanks a lot Mr. A., but I am looking for the center to this shape to have a different elevation. Check the photo I attached earlier, it’s a 3D shape where the center is going down in a parabolic way.
Other than a red curved labeled “Parabolic”, there is nothing in your image to indicate 3D.
Dear Sami,
Perhaps a better explanation is required- i had imagined you were looking to create surfaces, but now it seems to do something with the center; kindly elaborate for further assistance.
Best,
Mr .A
thanks for reply! I elaborated more. I appreciate it Mr. A.
Yes exactly! thanks a lot Ethan! I opened the file you attached but it is showing invalid mesh. What should I do? (I am new to GH).
I appreciate it A LOT. Another question if it’s fine, the study I am doing is actually to draw the hyperbolic paraboloid in GH by changing the number of sides using a slider.
So, I guess the network you sent me is for 3 sides (I tried it for 4 sides):
But I am looking for this guy for 4 sides:
Is there a way to allow to do that? like having a slider to draw the hypar given a slider specifying the number of sides. Thanks in advance anyways.
I don’t know what gave me the silly idea you were looking for three sides. Maybe it was the fact that your image was three-sided?
This is exactly what I am looking for! I followed through it and I understood it 
you saved my life. Thanks a lot.
