Hi, I tried to input my curves but it just turns up as Null Values and doesn't work This seems to be only component that I can find that patches a surface in GH I am using the newest Grasshopper 0.

I have already tried Marc's VB component but to no avail. Any suggestions? Share Tweet Facebook Facebook Views: Hi David, How can I patch 6 curves in grasshopper, rhino5. Thank you. Grasshopper handles NURBS surfaces similarly to the way that Rhino does because it is built on the same core of operations needed to generate the surface.

Any baked geometry will still use the higher mesh settings. In the previous section, we explained that NURBS surfaces contain their own coordinate space desfined by u and v domains. This means that two dimensional geometry that is defined by x and y coordinates can be mapped onto the uv space of a surface. The geometry will stretch and change in response to the curvature of the surface.

This is different from simply projecting 2d geometry onto a surface, where vectors are drawn from the 2d geometry in a specified direction until they intersect with the surface. You can think of projecting as geometry casting a shadow onto a surface, and mapping as geometry being stretched over a surface. Just as 2d geometry can be projected onto the uv space of a surface, 3d geometry that is contained by a box can be mapped to a corresponding twisted box on a surface patch. This operation is called box morphing and is useful for populating curved surfaces with three dimensional geometric components.

To array twisted boxes on a surface, the surface domain must be divided to create a grid of surface patches. The twisted boxes are created by drawing normal vectors at the corners of each patch to the desired height and creating a box defined by the end points of those vectors and the corner points of the patch.

In this example, we will use the box morph component to populate a NURBS surface with a geometric component. You should see a grid of twisted boxes populating your referenced surface. Change the U and V count sliders to change the number of boxes, and use the height slider to adjust their height. Powered by GitBook.
