The Face type exposes the following members.
Methods
| Name | Description | |
|---|---|---|
 | ComputeDerivatives | Returns the first partial derivatives of the underlying surface at the specified point. |
| | ComputeNormal | Returns the normal vector for the face at the given point. |
| | ComputeSecondDerivatives | Returns the second partial derivatives of the face at the specified point. |
| | Dispose | Causes the object to release immediately any resources it may be utilizing. (Inherited from APIObject .) |
| | Equals | (Inherited from GeometryObject .) |
| | Evaluate | Evaluates and returns the XYZ coordinates of a point at the indicated UV parameterization of the face. |
| | GetBoundingBox | Returns the UV bounding box of the face. |
| | GetEdgesAsCurveLoops | Returns a list of closed curve loops that correspond to the edge loops of the face. Curves in each curve loop correspond to individual edges. |
| | GetHashCode | Gets the integer value of the geometry object as hash code (Inherited from GeometryObject .) |
| | GetRegions | Gets the face regions (created, for example, by the Split Face command) of the face. |
| | GetType | Gets the Type of the current instance. (Inherited from Object .) |
| | Intersect(Curve) | Calculates the intersection of the specified curve with this face. |
| | Intersect(Face) | Calculates the intersection of the specified face with this face and returns the intersection results. |
| | Intersect(Curve, IntersectionResultArray ) | Calculates the intersection of the specified curve with this face and returns the intersection results. |
| | Intersect(Face, Curve ) | Calculates the intersection of the specified face with this face and returns the intersection results. |
| | IsInside(UV) | Indicates whether the specified point is within this face. |
| | IsInside(UV, IntersectionResult ) | Indicates whether the specified point is within this face and outputs additional information about the point location. |
| | Project | Projects the specified point on the face. |
| | ToString | Returns a string that represents the current object. (Inherited from Object .) |
| | Triangulate | Returns a triangular mesh approximation to the face. |
| | Triangulate(Double) | Returns a triangular mesh approximation to the face. |
Properties
| Name | Description | |
|---|---|---|
 | Area | The area of this face. |
| | EdgeLoops | A collection of edge loops. Each edge loop represents one of the closed boundaries of the face. |
| | GraphicsStyleId | The ElementId of the GeometryObject's GraphicsStyle (Inherited from GeometryObject .) |
| | HasRegions | Identifies if the face contains regions (which can be created, for example, by the Split Face command). |
| | IsCyclic | Indicates whether the underlying surface is periodic in the specified parametric direction. |
| | IsElementGeometry | Indicates whether this geometry is obtained directly from an Element. (Inherited from GeometryObject .) |
| | IsReadOnly | Identifies if the object is read-only or modifiable. (Inherited from APIObject .) |
| | IsTwoSided | Determines if a face is two-sided (degenerate). |
| | MaterialElementId | The element ID of the material from which this face is composed. |
| | Period | The period of the underlying surface in the specified parametric direction. |
| | Reference | Returns a stable reference to the face. |
| | Visibility | The visibility. (Inherited from GeometryObject .) |
