In the genmodel editor, right click on the top node labeled "Mysql" and generate the model Code (see Figure 9), the edit Code (see Figure 10), and finally the Topology edit Code (see Figure 11).

The third pattern, shown on the right, is called the "golden topology."

If one-click topology isn't the right answer for every situation, you can intuitively take control of the re-topology process with curves to assist in determining polygon flow.
