RuledSurface Class


Ruled Surface Class

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.

public class RuledSurface : Surface

The RuledSurface type exposes the following members.

Properties
Name Description
Public property IsValidObject Specifies whether the .NET object represents a valid Revit entity.
(Inherited from Surface )
Public property OrientationMatchesParametricOrientation Indicates whether this Surface's orientation is the same as or opposite to its parametric orientation.

Methods
Name Description
Public method Static member Create(Curve, Curve) Creates a Surface object coincident with the ruled surface joining two bounded generating curves.
Public method Static member Create(Curve, XYZ) Creates a Surface object coincident with the ruled surface joining a bounded generating curve to a point.
Public method Dispose
(Inherited from Surface )
Public method Equals Determines whether the specified object is equal to the current object.
(Inherited from Object )
Public method GetBoundingBoxUV Gets the UV bounding box of the surface.
(Inherited from Surface )
Public method GetFirstProfileCurve Returns a copy of the first profile curve if it is set.
Public method GetFirstProfilePoint If a point was used to define the first profile, returns a copy of that point.
Public method GetHashCode Serves as the default hash function.
(Inherited from Object )
Public method GetSecondProfileCurve Returns a copy of the second profile curve if it is set.
Public method GetSecondProfilePoint If a point was used to define the second profile, returns a copy of that point.
Public method GetType Gets the Type of the current instance.
(Inherited from Object )
Public method HasFirstProfilePoint Checks if a point was used to define the first profile.
Public method HasSecondProfilePoint Checks if a point was used to define the second profile.
Public method Project Project a 3D point orthogonally onto a surface (to find the nearest point). Throws InvalidOperationException if the projection fails.
(Inherited from Surface )
Public method ProjectWithGuessPoint 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 )
Public method ToString Returns a string that represents the current object.

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.
