Description

The AcDbPolygonMesh class represents the polygon mesh entity within AutoCAD.

A PolygonMesh is an M x N mesh, where M represents the number of vertices in a row of the mesh and N represents the number of vertices in a column of the mesh.

A mesh can be open or closed in either or both the M and N directions. A mesh that is closed in a given direction is considered to be continuous from the last row or column on to the first row or column.

All the vertices in the mesh are stored in a single list. For a non-surface-fit mesh, the first N vertices are used to make up the first column, the second N vertices are used to make up the second column, and so on until all the vertices are used up (there do not have to be enough vertices to fully fill the M x N mesh).

For a surface-fit mesh, the surface density values are used in place of M and N for the vertex row x column sizes.

Notes

Warning

Do not derive from this class. Attempting to do so will cause your application to halt AutoCAD.
