Revolved
|
A surface of revolution defined by a profile curve and a local coordinate system.
The surface is obtained by rotating the curve around Z axis of the local coordinate system.

Syntax
The RevolvedSurface type exposes the following members.
Properties
| Name | Description | |
|---|---|---|
|
Axis | Axis of the revolved surface. This is the Z axis of the local coordinate system associated with this revolved surface. |
|
|
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 ) |
|
|
Origin | Center of the circle that defines the base of the revolved surface. This is the origin of the local coordinate system associated with this revolved surface. |
|
|
XDir | X axis of the local coordinate system associated with this revolved surface. |
|
|
YDir | X axis of the local coordinate system associated with this revolved surface. |
Methods
| Name | Description | |
|---|---|---|
|
Create(Frame, Curve) | Creates a Surface object coincident with the surface of revolution defined by a coordinate frame and a profile curve. |
|
|
Create(XYZ, XYZ, Curve) | Creates a Surface object coincident with the surface of revolution defined by an axis and a profile curve. |
|
|
Create(Frame, Curve, Double, Double) | Creates a Surface object coincident with the surface of revolution defined by a coordinate frame, a profile curve, and start and end angles of revolution. |
|
|
Create(XYZ, XYZ, Curve, Double, Double) | Creates a Surface object coincident with the surface of revolution defined by an axis, a profile curve, and start and end angles of revolution. |

|
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 ) |
|
|
GetHashCode |
Serves as the default hash function.
(Inherited from Object ) |
|
|
GetProfileCurve | Returns a copy of the profile curve expressed in the surface's coordinate system. |
|
|
GetProfileCurveInWorldCoordinates | Returns a copy of the profile curve expressed in the world coordinate system. |
|
|
GetType |
Gets the
Type
of the current instance.
(Inherited from Object ) |
|
|
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 ) |
|
|
IsValidProfileCurve(Frame, Curve) | Checks if the input profile curve is valid to create a surface of revolution in the given frame of reference. |
|
|
IsValidProfileCurve(XYZ, XYZ, Curve) | Checks if the input profile curve is valid to create a surface of revolution around the given axis. |
|
|
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
The parametric equation of a surface of revolution is S(u, v) = center + C1(v)*cos(u)*xVec + C1(v)*sin(u)*yVec + C2(v)*zVec,
where the profile curve in the SurfRev's xz plane has the parametric equation (C1(t), C2(t)).
Note that the direction of X axis may agree or disagree with the chosen orientation of the surface.
