How do you add elevation points inside a created mesh

Issue description 

You have drawn a mesh but can only edit the elevation of the top surface from the corners.  How do you add extra nodes?

Solution 

You need to create an elevation point within your mesh.

1. Select the mesh and activate the Mesh Tool.
2. Choose the Geometry Method: Polygon.
3. Double-click on the desired location within the mesh to create a new node.

The New Mesh Point dialog will appear. Although the two radio buttons are greyed out due to your double-click action, you can still determine how the new node will affect the mesh.

Selecting the node will allow you to move it and give an elevation height, by selecting the Elevate Mesh Point command in the pet palette.
