IGESSolid_Loop Class Reference

defines Loop, Type <508> Form Number <1>
in package IGESSolid
A Loop entity specifies a bound of a face. It represents
a connected collection of face boundaries, seams, and
poles of a single face.

From IGES-5.3, a Loop can be free with Form Number 0,
else it is a bound of a face (it is the default)
