Examples
--------
Using a compas Mesh as an example:
>>> from compas.datastructures import Mesh
>>> from compas.geometry import Box, Frame
>>> from compas_rhino.utilities import draw_breps
>>> box = Box(Frame.worldXY(), 1.0, 2.0, 3.0)
>>> mesh = Mesh.from_shape(box)
Draw convert each mesh face to brep dict schema:
>>> vertices = mesh.vertices_attributes('xyz')
>>> breps = [{'points': mesh.face_coordinates(face)} for face in mesh.faces()]
Draw brep faces as one joined brep.
>>> guids = draw_breps(breps, join=True)
