How to use the rhino3dm.MeshType.Any function in rhino3dm

def import_render_mesh(context, ob, name, scale, options):
    # concatenate all meshes from all (brep) faces,
    # adjust vertex indices for faces accordingly
    # first get all render meshes
    og = ob.Geometry
    oa = ob.Attributes

    if og.ObjectType == r3d.ObjectType.Extrusion:
        msh = [og.GetMesh(r3d.MeshType.Any)]
    elif og.ObjectType == r3d.ObjectType.Mesh:
        msh = [og]
    elif og.ObjectType == r3d.ObjectType.Brep:
        msh = [og.Faces[f].GetMesh(r3d.MeshType.Any) for f in range(len(og.Faces)) if type(og.Faces[f])!=list]
    fidx = 0
    faces = []
    vertices = []
    # now add all faces and vertices to the main lists
    for m in msh:
        if not m:
            continue
        faces.extend([list(map(lambda x: x + fidx, m.Faces[f])) for f in range(len(m.Faces))])

        # Rhino always uses 4 values to describe faces, which can lead to
        # invalid faces in Blender. Tris will have a duplicate index for the 4th
        # value.

# Sample read render meshes from 3dm file
