# 1) If the model comes from the modified version that includes metadata
# then the OpenVSP components can be identified by type and retrieved
# by name. Otherwise the import methods just tries to make solid
# bodies from the components and gives them a generic name.
# 2) The import process attempts to sew the faces of the OpenVSP
# components together to form solids.
# 3) If a surface is found to be planar, it is replaced with a plane
# before sewing. This helps eliminate some degenerated edges.
# 4) Faces sharing the same domain are unified. If flat wing caps are
# used, this usually results in a single face for the entire cap
# rather than two faces split between the upper and lower surface.
