Subd rhino12/20/2023 ![]() But not only that, you will learn how to modify SubD geometry, select and extract SubD edges, convert SubD to Mesh, and vice versa. These are the components that allow us to reference SubD geometry into Grasshopper. In this tutorial, we will go through some of the newest features for Grasshopper that come with Rhino 7. Edges on the boundary are also crease edges.Ī vertex that is attached to only smooth edges.Īny vertex that is between exactly two creased edges that form a smooth crease.Ī vertex at a sharp corner between two crease edges and any vertex attached to three or more crease edges.Ī vertex attached to exactly one crease edge.Apply for Rhino for Architects Training □ Įxtended Tutorial + Extra Project Files □ Rhino SubD objects have two types of edges (crease and smooth), and four types of vertices (smooth, crease, corner, and dart).Īn edge that smoothly connects two faces.Ī hard edge that connects two faces. Press the Tab key or use the SubDDisplayToggle command to switch SubD objects between flat and smooth modes. The Rhino SubD Rules document provides the gold standard technical description of the mathematical definition used by Rhino SubD objects. Most SubD creation and editing commands can be found on the SubD menu and SubD Tools toolbar. They can be converted to either high-quality NURBS or mesh (quads or triangles) objects, and exported to file formats (e.g., IGES, STEP, OBJ, STL.) that support either meshes or NURBS. SubD objects in Rhino are measurable and manufacturable. ![]() Rhino SubD objects are high-precision Catmull Clark subdivision surfaces designed to quickly model and edit complex organic shapes.
