Creating rectangular meshes

You can create a three-dimensional rectangular mesh consisting of four-sided polygons. You determine the size of the mesh by specifying the number of vertices along the primary (M-direction) and secondary (N-direction) mesh axes and then specifying the coordinates for each vertex.

To create a rectangular mesh

Advanced experience level

  1. Do one of the following:
    • Choose Insert > 3D Entities > Mesh.
    • On the Draw 3D toolbar, click the Mesh tool ().
    • Type mesh and then press Enter.
  2. Specify the number of vertices along the primary mesh axis.
  3. Specify the number of vertices along the secondary mesh axis.
  4. Specify the coordinates for each vertex.
  5. Specifying the coordinates for the last vertex completes the mesh and ends the command.

TIP   Although creating rectangular meshes manually can be exacting, they are useful for representing complex surfaces such as three-dimensional terrain models. The Mesh tool is most useful when combined with scripts or LISP programs that mathematically calculate the coordinates of the vertices.
