WARNING
GSA-Grasshopper plugin [GsaGH] is pre-release and under active development, including further testing to be undertaken. It is provided "as-is" and you bear the risk of using it. Future versions may contain breaking changes. Any files, results, or other types of output information created using GsaGH should not be relied upon without thorough and independent checking.

# Description
Members in GSA are geometrical objects used for design that can automatically find intersections with other members. From members, we can create the elements used for analysis. Members are more closely related to building objects, e.g., a beam, column, slab or wall.
A Member2D is the planar/area geometry resembling for instance a slab or a wall. They can be defined geometrically by a planar Brep.
