Simulation Model editor
The Simulation Model editor can be used to visually edit a process model.
Simulation models are saved with the file extension *.bpm.
Any number of editors can be open at once, but only one can
be active at a time. The main menu bar and toolbar for the editor view contain
operations that are applicable to the active diagram.
Tabs in the editor area indicate the names of
resources that are currently open for editing. An asterisk (*) indicates that
an editor has unsaved changes. To close an editor, click the X on the
tab. 
Context menus are available by right-clicking objects within the editor. Functionality offered by the menus vary based on the type
of object selected. For example, the option to add or remove triggers is available only for start and intermediate events, while
the option to set or apply default characteristics of new diagram objects is always available.
Selecting Set appearance default on an existing object in the diagram, newly
created objects of the same type will have the characteristics of the existing
object (color, font, font size, shape, etc.)
