Leveraging NURBS: Extracting planes from curves

- [Instructor] I have my exercise file open already. In this video I want to talk about extracting planes from curves. This is a really common operation in Grasshopper if you want to use curves as the basis for 3D surface geometry. I go to curve, analysis. I see here there's two ways to extract planes. So, I'm going to grab each of them. And I'll plug my path curve in. And I'll plug my range of values in. The range is set from zero to one and the path is re-parametrized to make sure that I'm evenly spacing along the path. So the horizontal frames, the Z vector of the plane will always be facing up. That's not particularly useful for lofting so I'm going to get rid of that. Now the perpendicular frames the axes are based on the tangent to the curve so the Z value of these planes is tangent to the curve and then the X and Y are based on the maximum curvature. So you can see it's twisting as the curvature of my path is changing. So let's test this out. If I go to transform, orient, plug…
