RuledSurface

Public 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.
(Inherited from Surface)

---

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.
(Inherited from 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.
