Exports and imports using Rhino Compute

Hello Robert,
Here are a few samples:

The latter includes a C# script component in the gh definition with the following code:

    if( null == data || null == ext ) return;

    var decodedData = Convert.FromBase64String(data);

    var tmpPath = Path.GetTempFileName();
    tmpPath = Path.ChangeExtension(tmpPath, ext);

    Print(tmpPath);

    File.WriteAllBytes(tmpPath, decodedData);

    if(File.Exists(tmpPath))
    {
      using( var doc = Rhino.RhinoDoc.CreateHeadless(null)){

        doc.Import(tmpPath);

        var ros = doc.Objects.FindByObjectType(Rhino.DocObjects.ObjectType.Mesh);

        Print("Number of meshes: {0}", ros.Length);

        var meshes = new List<Rhino.Geometry.Mesh>();
        foreach( Rhino.DocObjects.RhinoObject obj in ros )
        {
          meshes.Add(obj.DuplicateGeometry() as Rhino.Geometry.Mesh);
        }

        A = meshes;
      }
    }

So as you can see, you pass a b64 encoded file (stl, dwg, or whatever Rhino supports), you save that file on the server, you create a headless doc, and you import the file into the headless doc. You should tailor this example to handle the objects you are interested in.
