Revit 2025.3 API
Curve |
A class that encapsulates the notion of a curve in the 2D parameter space of a surface in 3D space.

SystemObject
Autodesk.Revit.DBCurveUV
Autodesk.Revit.DBCurveUV
Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.3.0.0 (25.3.0.0)
Syntax
The CurveUV type exposes the following members.

Name | Description | |
---|---|---|
![]() | IsBound | Describes whether the parameter of the curve is restricted to a particular interval. |
![]() | IsValidObject | Specifies whether the .NET object represents a valid Revit entity. |

Name | Description | |
---|---|---|
![]() | As3DCurveInXYPlane | Returns a 3D curve lying in the XY plane in XYZ coordinates, representing the 2D curve with its UV coordinates identified with XY coordinates. |
![]() | ComputeDerivatives | Computes the first derivative, the second derivative and the unit tangent vector at the specified parameter along the curve. |
![]() ![]() | Create | Create a CurveUV from a bounded 3D Curve lying in the XY plane. |
![]() | Dispose | Releases all resources used by the CurveUV |
![]() | Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
![]() | Evaluate | Evaluates and returns the point at the specified parameter along the curve. |
![]() | GetEndParameter | Gets the raw parameter value at the start or end of this curve. |
![]() | GetHashCode | Serves as the default hash function. (Inherited from Object) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object) |
![]() | Transform | Transform this CurveUV by the given 2D affine transform if possible. |

Revit does not have a class to represent 2D curves explicitly.
