# 3DMESH Command [GstarCAD 2022](Help%20System/GSTARCAD/2022/Index.md) → [Commands](Help%20System/GSTARCAD/2022/Commands/(Commands).md) → [3D](Help%20System/GSTARCAD/2022/Commands/3D/(3D).md) ## Function Description: This command is used to create polygonal mesh in any styles. The density of the mesh controls number of mosaic surfaces. The mesh is defined by M×N vertices of rectangles, this is similar to row and column of grid. It is a traditional way to create mesh by the 3DMESH command and designed for program operation rather than manual operation. ## Command Access: > **Icon:** >  > **Menu:** Draw \> Modeling \> Meshes \> 3D Mesh > **Ribbon:** 3D \> Mesh \> 3D Mesh > **Toolbar:** / > **Command:** 3DMESH > **Alias:** / ## Command Prompts: Enter size of mesh in M direction: Enter size of mesh in N direction: Specify location for vertex (0, 0): ## **Size of mesh in M direction** Specifies the size of mesh in M direction, it is a value between 2 and 256\. ## **Size of mesh in N direction** Specifies the 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\)** Specifies coordinates for each vertex. Users can enter 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). Defines vertex coordinate beginning with (0, 0\) and firstly specifies the vertex coordinate with M, and then specifies M\+1. The distance of vertex can be any value and directions of M and N are determined by their coordinate locations. Meshes created by the 3DMESH command are open in M and N direction, users can use PEDIT command to close them.
