Properties
Name
Description
Public Property
Axis
Axis of the revolved surface. This is the Z axis of the local coordinate system associated with this revolved surface.
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)
Public Property
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.
Public Property
XDir
X axis of the local coordinate system associated with this revolved surface.
Public Property
YDir
X axis of the local coordinate system associated with this revolved 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
GetHashCode
Serves as the default hash function.
(Inherited from Object)
Public Method
GetProfileCurve
Returns a copy of the profile curve expressed in the surface’s coordinate system.
Public Method
GetProfileCurveInWorldCoordinates
Returns a copy of the profile curve expressed in the world coordinate system.
Public Method
GetType
Gets the Type of the current instance.
(Inherited from Object)
Public Method
Static Member
IsValidProfileCurve(Frame, Curve)
Checks if the input profile curve is valid to create a surface of revolution in the given frame of reference.
Public Method
Static Member
IsValidProfileCurve(XYZ, XYZ, Curve)
Checks if the input profile curve is valid to create a surface of revolution around the given axis.
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
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.
