Ruled
|
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.

Syntax
The RuledSurface type exposes the following members.
Properties
| Name | Description | |
|---|---|---|
|
IsValidObject |
Specifies whether the .NET object represents a valid Revit entity.
(Inherited from Surface ) |
|
|
OrientationMatchesParametricOrientation |
Indicates whether this Surface's orientation is the same as or opposite to its parametric orientation.
(Inherited from Surface ) |
Methods
| Name | Description | |
|---|---|---|
|
Create(Curve, Curve) | Creates a Surface object coincident with the ruled surface joining two bounded generating curves. |
|
|
Create(Curve, XYZ) | Creates a Surface object coincident with the ruled surface joining a bounded generating curve to a point. |
|
|
Dispose |
(Inherited from Surface ) |
|
|
Equals |
Determines whether the specified object is equal to the current object.
(Inherited from Object ) |
|
|
GetBoundingBoxUV |
Gets the UV bounding box of the surface.
(Inherited from Surface ) |
|
|
GetFirstProfileCurve | Returns a copy of the first profile curve if it is set. |
|
|
GetFirstProfilePoint | If a point was used to define the first profile, returns a copy of that point. |
|
|
GetHashCode |
Serves as the default hash function.
(Inherited from Object ) |
|
|
GetSecondProfileCurve | Returns a copy of the second profile curve if it is set. |
|
|
GetSecondProfilePoint | If a point was used to define the second profile, returns a copy of that point. |
|
|
GetType |
Gets the
Type
of the current instance.
(Inherited from Object ) |
|
|
HasFirstProfilePoint | Checks if a point was used to define the first profile. |
|
|
HasSecondProfilePoint | Checks if a point was used to define the second profile. |
|
|
IsCoincidentWith |
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 ) |
|
|
Project |
Project a 3D point orthogonally onto a surface (to find the nearest point).
Throws InvalidOperationException if the projection fails.
(Inherited from Surface ) |
|
|
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 ) |
|
|
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));
