I use Rhino3dmIO to support 3dm file format as an export option for my app.
So I create new 3dm files from scratch, based on mesh data created by my app.
Currently I do:
var m = new Rhino.Geometry.Mesh(); var verts = mesh.Vertices.Select(x => new Rhino.Geometry.Point3d(x.X, x.Y, x.Z)); var faces = mesh.Triangles.Select(x => new Rhino.Geometry.MeshFace(x.P0, x.P1,x.P2)); m.Vertices.AddVertices(verts); m.Faces.AddFaces(faces); ....
Which works well.
There are a couple of things that I have not been able to figure out, which would really improve the quality of the 3dm file export.
- How to add a texture/material to a mesh? I have an image, and some parameters, how do I create a material from those, and how do I apply that to the mesh?
- How to create blocks/instances? I have lots of duplicate geometry, which I would prefer would stay grouped, like “blocks” in dxf for example, so that editing one edits all.
Thank you for your time!
