I am new at grasshopper, and while following a tutorial I realized that I want to make the parametric surface within the bounds of an oval.
I only see 4 sided surfaces and curves tutorials, but no flat circles. Whenever I make my circle into a boundary surface and plug into as a plane in the TriGrid, the final parametric form disappears. Hopefully someone can show me where I can put this oval shape so that grasshopper knows only to make the new parametric surface within the oval bound.
However, you can generate a triangular grid and select triangles within a curve, turn the triangles into a mesh and use Kangaroo to pull the vertices to the boundary curve. Some of the edge lengths will change, depending on the strength values.
