Rhinocommon brep to mesh

Hello everybody.

How do I convert a brep to mesh using Rhinocommon methods?

public Rhino.Geometry.Mesh CreateMesh() {
            Rhino.Geometry.Mesh myMesh = new Rhino.Geometry.Mesh();
            Rhino.Geometry.Point3d pt0 = new Rhino.Geometry.Point3d(0, 0, 0);
            Rhino.Geometry.Point3d pt1 = new Rhino.Geometry.Point3d(10, 10, 10);
            Rhino.Geometry.BoundingBox box = new Rhino.Geometry.BoundingBox(pt0, pt1);
            Rhino.Geometry.Brep brep = box.ToBrep();
            myMesh = Rhino.Geometry.Mesh.CreateFromBrep(brep); // Line 7

return myMesh;

}

Line 7 generates an error: Error 1 Cannot implicitly convert type 'Rhino.Geometry.Mesh[]' to 'Rhino.Geometry.Mesh'

Feel like I have to convert the type myself but have no idea how to do so.

Thank you

that means that this statement

Rhino.Geometry.Mesh.CreateFromBrep(brep)

will return a list of meshes, rather than a single mesh. You can probably find a function in RhinoCommon that welds multiple meshes into one, but basically you just need to deal with the list.

Mesh.Append()

Thanks, guys

Apparently, if I only have one mesh being drawn, it is assigned an index of [0]. So all I had to do was to specify that index in the CreateFromBrep method, like this:

myMesh = Rhino.Geometry.Mesh.CreateFromBrep(brep)[0];
