This video covers the basics of constructing surface geometry from a list of boundary curves and by extrusion, and solid 3D geometry by extrusion and loft. For each example, we will first create a single surface or solid element, then identify how data needs to be structured to create multiple elements. Nodes used: Surface.ByPatch, Curve.Extrude, Curve.ExtrudeAsSolid, Solid.ByLoft.
- Now we're ready to take some of the curves…in our Dynamo graph and use them to create…surfaces and solids.…Let's begin by opening the SurfacesAndSolids exercise file,…which contains three groups of nodes from previous videos.…The first group of nodes contains a list of polygons,…which is a square and a triangle.…The top-right group of nodes creates a vector…that we use to translate or move those polygons.…And finally, the bottom-right group of nodes…was used to rotate each of those polygons…around their center points.…
For the moment, I'm going to hide the previews…on the geometry coming out of the Translate…and the Rotate nodes.…Let's begin with one of the simplest methods…of creating a surface, a surface ByPatch,…which we'll in the Geometry-Surface section…of the node library.…This node will take a closed curve as an input,…and it'll generate a surface using…that curve as its boundary edges.…We can see that the single input…of the Surface.ByPatch node is asking for a curve.…
As I mentioned in a previous video, the Dynamo…
