Mesh Class 
This is often called a facevertex mesh.
Namespace: Rhino.Geometry
The Mesh type exposes the following members.
Name  Description  

Mesh  Initializes a new empty mesh.  
Mesh(SerializationInfo, StreamingContext) 
Protected constructor for internal use.

Name  Description  

ComponentStates 
Gets access to the vertex hidden/visibility collection in this mesh.
This is a runtime property and it is not saved in the 3dm file.
 
DisjointMeshCount 
Gets the number of disjoint (topologically unconnected) pieces in this mesh.
 
Disposed 
Indicates if this object has been disposed or the
document it originally belonged to has been disposed.
(Inherited from CommonObject.)  
FaceNormals 
Gets access to the face normal collection in this mesh.
 
Faces 
Gets access to the mesh face list.
 
HasBrepForm 
Returns true if the Brep.TryConvertBrep function will be successful for this object
(Inherited from GeometryBase.)  
HasCachedTextureCoordinates 
Will return true if SetCachedTextureCoordinates has been called;
otherwise will return false.
 
HasPrincipalCurvatures 
HasPrincipalCurvatures
 
HasUserData 
Gets true if this class has any custom information attached to it through UserData.
(Inherited from CommonObject.)  
IsClosed 
Returns true if every mesh "edge" has two or more faces.
 
IsDeformable 
true if object can be accurately modified with "squishy" transformations like
projections, shears, and nonuniform scaling.
(Inherited from GeometryBase.)  
IsDocumentControlled 
If true this object may not be modified. Any properties or functions that attempt
to modify this object when it is set to "IsReadOnly" will throw a NotSupportedException.
(Inherited from GeometryBase.)  
IsOriented 
Returns true if the mesh is manifold and every pair of faces that share an "edge" have compatible orientations.
 
IsSolid 
Returns true if the mesh is solid. A "solid" is a closed oriented manifold.
 
IsValid  Tests an object to see if it is valid. (Inherited from CommonObject.)  
Ngons 
Gets access to the mesh ngon list.
Ngons represent groups of Faces (triangles + quads). Faces are used to tessellate an Ngon internally. When a triangle or quad is referenced in the Ngon list, it is no longer visualized and conceived as a single entity, but takes part of the Ngon. If you need to get access to both Ngons and the faces that are not referenced by Ngons, that is, all polygons that are visible in the mesh, then use the GetNgonAndFacesEnumerable helper method.

basic object types like points, curves, surfaces, and so on.

on the last call to CreatePartitions

This object stores vertex connectivity and the indices of vertices that were unified while computing the edge topology.  
UserData
