virtual void stream(
const AcGeEllipArc3d & arc );
§StreamAcad
base class vectorises the ellipse into line segments
§These
are pushed back into the stream via the virtual function
virtual
void streamWcs( const AcGePoint3d & start, const AcGePoint3d & end
);
§StreamVector
derived class will override streamWcs() but not ellipse
§StreamExplode
will override both, to produce
§Real AutoCAD ellipse for an ellipse
§AutoCAD lines for other line segments that
cannot be handled at a higher level
