Revit 2025.3 API
Plane Class |
A Planar surface.
Inheritance HierarchyNamespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.3.0.0 (25.3.0.0)
Syntax
The Plane type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | IsValidObject |
Specifies whether the .NET object represents a valid Revit entity.
(Inherited from Surface) |
| Normal | Plane normal. |
| OrientationMatchesParametricOrientation |
Indicates whether this Surface's orientation is the same as or opposite to its parametric orientation.
(Inherited from Surface) |
| Origin | Plane origin. |
| XVec | Axis defining the first parametric direction of the plane. |
| YVec | Axis defining the second parametric direction of the plane. |
Methods| Name | Description | |
|---|---|---|
  | Create | Creates a Plane object defined by a local frame of reference. |
| CreateByNormalAndOrigin | Constructs a Plane object from a normal and an origin represented as XYZ objects. Follows the standard conventions for a planar surface. The constructed Plane object will pass through origin and be perpendicular to normal. The X and Y axes of the plane will be defined arbitrarily. |
| CreateByOriginAndBasis | Creates a Plane object defined by the two orthogonal unit vectors and passing through the origin point supplied as arguments. |
| CreateByThreePoints | Creates a Plane object passing through three points supplied as arguments. |
| 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) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| 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 the plane is S(u, v) = origin + u*xVec + v*yVec.
