Toolbar: Apply Section: Applies the section location's spatial view to the viewport and displays the 2d section graphics. Open Drawing: Navigates to the section drawing view.

Disabled if no such attachment exists. see HyperModelingConfig to override the default handler by supplying a subclass of SectionMarkerHandler. see HyperModelingDecorator for various methods that might be usefully wired up to marker click or toolbar actions.
