17 class MakeArcOfParabola from GC inherits Root from GC
18 ---Purpose: Implements construction algorithms for an arc
19 -- of parabola in 3D space. The result is a Geom_TrimmedCurve curve.
20 -- A MakeArcOfParabola object provides a framework for:
21 -- - defining the construction of the arc of parabola,
22 -- - implementing the construction algorithm, and
23 -- - consulting the results. In particular, the
24 -- Value function returns the constructed arc of parabola.

32 raises NotDone from StdFail
36 Create(Parab : Parab from gp ;
37 Alpha1, Alpha2 : Real from Standard ;
38 Sense : Boolean from Standard ) returns MakeArcOfParabola;
39 ---Purpose: Creates an arc of Parabola (TrimmedCurve from Geom) from
40 -- a Parabola between two parameters Alpha1 and Alpha2
41 -- (given in radians).
43 Create(Parab : Parab from gp ;
45 Alpha : Real from Standard ;
46 Sense : Boolean from Standard ) returns MakeArcOfParabola;
47 ---Purpose: Creates an arc of Parabola (TrimmedCurve from Geom) from
48 -- a Parabola between point <P> and the parameter
49 -- Alpha (given in radians).
51 Create(Parab : Parab from gp ;
54 Sense : Boolean from Standard ) returns MakeArcOfParabola;
55 ---Purpose: Creates an arc of Parabola (TrimmedCurve from Geom) from
56 -- a Parabola between two points P1 and P2.
58 Value(me) returns TrimmedCurve from Geom
61 ---Purpose: Returns the constructed arc of parabola.
