# IGESGeom_CircularArc Class Reference

defines IGESCircularArc, Type <100> Form <0>
in package IGESGeom
A circular arc is a connected portion of a parent circle
which consists of more than one point. The definition space
coordinate system is always chosen so that the circular arc
remains in a plane either coincident with or parallel to
the XT, YT plane.
