class MakeArcOfEllipse from GC inherits Root from GC
|
|
|
|
---Purpose: Implements construction algorithms for an arc
|
|
-- of ellipse in 3D space. The result is a Geom_TrimmedCurve curve.
|
|
-- A MakeArcOfEllipse object provides a framework for:
|
|
-- - defining the construction of the arc of ellipse,
|
|
-- - implementing the construction algorithm, and
|
|
-- - consulting the results. In particular, the
|
|
-- Value function returns the constructed arc of ellipse.
