1 Click Publish (viewable from any tab). The HTML Generator presents you with a dialog warning you that HTML creates (and potentially overwrite) files and directories in the path you chose.
2 Select OK to proceed.
When definitions are selected to be generated, there are always two passes that are done. The first pass, gets all of the definitions and processes the diagrams. The second pass processes the definitions. The more diagrams you select, the longer it takes the generator to publish.
Anytime during the generation process it is possible to stop the run by clicking Cancel. The generator stops at the next opportunity.
