Revit 2025.3 API
Mesh Class |
A triangular mesh.
Inheritance HierarchyNamespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.3.0.0 (25.3.0.0)
Syntax
The Mesh type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | DistributionOfNormals | Indicates the distribution of normal vectors along the tessellated mesh surface. |
| GraphicsStyleId | The ElementId of the GeometryObject's GraphicsStyle (Inherited from GeometryObject) |
| Id | A unique integer identifying the GeometryObject in its associated non view-specific GeometryElement. (Inherited from GeometryObject) |
| IsClosed | Indicates whether the mesh is closed. |
| 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) |
| MaterialElementId | Element ID of the material from which this mesh is composed. |
| NumberOfNormals | The number of normals associated with the mesh. |
| NumTriangles | The number of triangles that the mesh contains. |
| Transformed | Transforms this mesh and returns the result. |
| Triangle | Retrieves a specific triangle. |
| Vertices | Retrieves all vertices used to define this mesh. Intended for indexed access. |
| Visibility | The visibility. (Inherited from GeometryObject) |
Methods| Name | Description | |
|---|---|---|
 | ComputeSurfaceArea | Computes and returns the surface area of the mesh. The surface area is the sum of the areas of the constituent facets of the mesh. |
| Dispose | Causes the object to release immediately any resources it may be utilizing. (Inherited from APIObject) |
| Equals | Determines whether the specified Object is equal to the current Object. (Inherited from GeometryObject) |
| GetHashCode |
Gets the integer value of the geometry object as hash code
(Inherited from GeometryObject) |
| GetNormal | Returns a normal unit vector at the given index. |
| GetNormals | Returns all normals assigned to the mesh. |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
RemarksMeshes are generated during triangulation of faces. They can also be encountered directly in Revit geometry (typically imported geometry).
Meshes contain a single array of Vertices, and a corresponding array of triangles. Triangles can be accessed by index from
TriangleInt32, and reference 3 vertices from the Vertices array.
