Thanks for the amazing resource you have here
I am not sure which tools to utilize in order to create a particular shape from a plane or curve.
My end goal is to some how apply this geometry to a poly surface, or at least to a curve - for example -a circle centred on the apex of this shape
Do I create a curve (circle) on a square surface, group the two, then manipulate the control points so that the surface and the circle curve end up approximating shape of the picture I have attached?
Do I have to drag each individual control point on the circle in such a way to approximate the surface shape in question, or is there a more elegant way to accomplish this?
Essential I want to raise the centre of a square plane (or planar curves), but with creases diagonally across (square), such that the crease lines remain straight and the rest of the surface sags creating a curved surface. Imagine a square sheet loosely secured at corners with diagonal lengths of rope supporting underneath, then raise the centre point with sheet anchored only at corners.
If I can apply this to a a group of planar curves, by by spliting the group diagonally, then have it conform to surface I have described, as though it were drawn uponit , then I could join the parts into a closed curve and I would have the shape I am trying to model.
Ideally I would want to be able to fine tune and tweak the distance the centre has been raised from its original planar position.
Could someone please point me in the right direct of which tools to use to approach this in rhino?
And if there is a better or different way to ahieve this please let me know.
