Right-click the second Curve parameter and select “Set one curve.” Select the second rail curve in the Rhino viewport Right-click the first Curve parameter and select “Set one curve.” Select the first rail curve in the Rhino viewport Surface/Freeform/Sweep2 – Drag a Sweep2 component onto the canvas Params/Geometry/Curve – Drag and drop three curve parameters onto the canvas Start a new definition, type Ctrl+N (in Grasshopper) Extrude the curves to create intersecting fins.Prune the tree to cull branches containing insufficient points to construct a degree 3 NURBS curve and interpolate points.Explode the tree to connect corner points and draw diagonal lines across each segement.Data comprised of four lists, each containing a single corner point of each segment. Flip the matrix to change the data structure.Data comprised of one list with four items in each segment. Divide the surface into variable sized segments, extract vertices.Sweep with two rails to create a NURBS surface.In this example, we will use some of Grasshopper’s tools for manipulating data trees to retreive, reorganize, and interpolate the desired points contained in a data tree and create a lattice of intersecting fins. After intstallation you can found plugin under Params > Scatter.Example files that accompany this section:.Right-click the file > Properties > make sure there is no "blocked" text.
In Grasshopper, choose File > Special Folders > Components folder.Instantly bakes geometry with attributes into a new layer called "Scatter".Rotation and Scale values - Randomly transforms geometry (or pre-define values as a list).
