[GstarCAD 2021](Help%20System/GSTARCAD/2021/Index.md) → [Commands](Help%20System/GSTARCAD/2021/Commands/(Commands).md) → [3D](Help%20System/GSTARCAD/2021/Commands/3D/(3D).md)
The 3DMESH command is used to create polygonal mesh in any styles.
**Command Access:**
> **Ribbon:** 3D \> Mesh \> 3D Mesh
> **Menu:** Draw \> Modeling \> Meshes \> 3D Mesh
> **Command:** 3DMESH
**Command Prompts:**
> Enter size of mesh in M direction:
> Enter size of mesh in N direction:
> Specify location for vertex (0, 0):
> Specify location for vertex (0, 1):
**Function Description:**
The density of mesh controls number of mosaic surface. The mesh is defined by M×N vertexes of rectangles, this is similar to row and column of grid. It is a traditional way to create mesh by 3DMESH command and designed for program operation rather than manual operation.
**Relative Glossary:**
**Size of mesh in M direction:**
Specify size of mesh in M direction, it is a value between 2 and 256\.
**Size of mesh in N direction:**
Specify size of mesh in N direction, it is a value between 2 and 256\. The value of M×N must be equal to the specified vertex number.
**Location for vertex (0, 0):**
Specify coordinates for each vertex. Users could input two dimension or three dimension coordinates. The location for each vertex is determined by the M and N (M is the subscript of row and N is the subscript of column). Define vertex coordinate beginning with (0, 0\) and firstly specify the vertex coordinate with M, and then specify M\+1.
The distance of vertex could be any value and directions of M and N are determined by their coordinate locations.
Meshes created by 3DMESH command are open in M and N direction; users could use PEDIT command to close them.
