HFSS15: Upgrade Version in History Tree Shortcut Menu

By right-clicking on an operation icon in the history tree in the Modeler window, you can see the Upgrade Version command.

The Modeler by default opens the legacy project in previous (what ever that the project was saved with) ACIS version so that you don't see side effects of slight topology changes between ACIS versions. If you want you can use Upgrade Version to move the operation to use latest ACIS code. Typically this applies when a needed fix is available with new ACIS version.
