RuledSurface

Description:
A ruled surface is created by sweeping a line between two profile curves or between a curve and a point (a point and a curve). Input curve(s) must be bounded or have natural bounds.

Remarks:
Both curves are evaluated in normalized parameters [0, 1] The parametric equations of a ruled surface are:

Curve C1 and curve C2 : S(u, v) = C1(u) + v * (C2(u) - C1(u));
Point P1 and curve C2 : S(u, v) = P1 + v * (C2(u) - P1);
Curve C1 and point P2 : S(u, v) = C1(u) + v * (P2 - C1(u));

The point/point case is not allowed as that would define a degenerate ruled surface.

Name	Return Type	Description	Inherited From
M Create(Curve, Curve)	Surface	Creates a Surface object coincident with the ruled surface joining two bounded generating curves.
M Create(Curve, XYZ)	Surface	Creates a Surface object coincident with the ruled surface joining a bounded generating curve to a point.
M Dispose()	None	(Inherited from Surface )	Surface
M Equals	None	Determines whether the specified object is equal to the current object. (Inherited from Object )	Object
M GetBoundingBoxUV()	BoundingBoxUV	Gets the UV bounding box of the surface. (Inherited from Surface )	Surface
M GetFirstProfileCurve()	Curve	Returns a copy of the first profile curve if it is set.
M GetFirstProfilePoint()	XYZ	If a point was used to define the first profile, returns a copy of that point.
M GetHashCode	None	Serves as the default hash function. (Inherited from Object )	Object
M GetSecondProfileCurve()	Curve	Returns a copy of the second profile curve if it is set.
M GetSecondProfilePoint()	XYZ	If a point was used to define the second profile, returns a copy of that point.
M GetType	None	Gets the Type of the current instance. (Inherited from Object )	Object
M HasFirstProfilePoint()	Boolean	Checks if a point was used to define the first profile.
M HasSecondProfilePoint()	Boolean	Checks if a point was used to define the second profile.
M IsCoincidentWith(Surface)	Boolean	Determine if two surfaces are coincident (ignoring Envelopes). For an affirmative answer, the surfaces must have the same type (e.g., two planes). (Inherited from Surface )	Surface
M Project(XYZ, UV%, Double%)	None	Project a 3D point orthogonally onto a surface (to find the nearest point). Throws InvalidOperationException if the projection fails. (Inherited from Surface )	Surface
M ProjectWithGuessPoint(XYZ, UV, UV%, Double%)	None	Project a 3D point orthogonally onto a surface (to find the nearest point). This method is meant to be used when a good approximate solution for the projection is available. Throws InvalidOperationException if the projection fails. (Inherited from Surface )	Surface
M ToString	None	Returns a string that represents the current object. (Inherited from Object )	Object
