struct Net

The AcDbSubDMesh subclass of a MESH: its vertices, faces, edges and creases.

Field	Type and default	Meaning
`Version`	`int{2}`	The version of the mesh's layout. Group 71.
`Blend`	`int`	Whether creases are blended. Group 72.
`Level`	`int`	The level of subdivision smoothing. Group 91.
`Vertices`	`std::vector<Vector>`	The vertices; group 92 counts them. Groups 10, 20, 30.
`Faces`	`std::vector<int>`	The faces, each its vertex count and then the index of each vertex; group 93 counts the numbers. Group 90.
`Edges`	`std::vector<int>`	The edges, as pairs of vertex indices; group 94 counts the pairs. Group 90. A MESH whose count of indices is odd is not written, and one read so is kept as it came.
`Creases`	`std::vector<double>`	The crease of each edge; group 95 counts them. Group 140.
`Overridden`	`int`	The number of parts of the mesh whose properties are overridden. Group 90.
`Overrides`	`std::vector<Group>`	The overrides that follow, kept as the groups they came in.

A MESH: a subdivision surface of faces, edges and creases.

Field	Type	Meaning
`Record`	`Entities::Record`	The layer, linetype, color and the rest every entity carries.
`Picture`	`std::string`	The proxy graphics, for programs that cannot draw the entity. Group 92, or 160 from R2010, then 310.
`Net`	`Boxed<Entities::Net>`	The vertices, faces, edges and creases, from the AcDbSubDMesh subclass.
