I believe there are not many tutorials out there, thank you for the feedback. Here I'm attaching the original drawing of the bird with step-by-step comments to explain. Just remember that the current release of WeaverBird only works on meshes and does not accept NURBS surfaces inputs. Each command works on each single mesh face.
You can use the _Mesh command in Rhino to automatically transform a NURBS surface into a mesh, or you can draw the mesh manually with _3dFace, _MeshPolyline, _MeshPlane, _MeshBox, etc... and then use any wb command to transform it. All WeaverBird commands start with "wb". You can use the _CommandHelp command in Rhino to see a short help for most of these commands, or right-click in Grasshopper on a component.
I'd personally like WeaverBird to have more topological tools for designing, so that additional transformations can become possible and easy to use. I hope this helps,
Thanks very much and the step-by-step instructions in the 3dm file provide me a clear conception of mesh and the grids in it.
Would you please send me some more files which can tutor me? I want to learn more about the plug-in because I am really interested in it! Thanks again!
