Create A BPMN Diagram

On Dragon1, you can create BPMN diagrams. These diagrams are suitable for modeling business processes. This page is a tutorial for creating a simple BPMN diagram or in other words a process model.

What is BPMN?

BPMN is the world standard for modeling business processes. OMG is the owner of the specification. BPMN is an open-source (free of charge) modeling language.

How To Create a BPMN Diagram

To create a BPMN diagram with the preselected BPMN Shapes in the Visual Designer:

  • Click on 'Select Diagram Type' at the top of the Shapes Panel at the right (under the Explorer Treeview)
  • Select diagram type 'Process Diagram - BPMN'
  • Now you see the basic set of BPMN Shapes
  • Drag a lane to the canvas and size it
  • Draw a start and stop event to the canvas, select the shapes and name them (go to the Inspector, expand the Text Attributes panel and enter a title for the shape in the Name field)
  • Drag a few tasks to the canvas and name them
  • Drag a few decisions to the canvas and name them
  • Connect the shapes with links by selecting a shape and use the Arrow smart tool to drag a link to another shape

BPMN as Open Standard


The Object Management Group® (OMG®) is the international not-for-profit standards consortium. OMG has standards that are driven by end-users, vendors, government agencies and academic institutions. OMG develops standards for a wide range of technologies. Three well-known standards of OMG are the Unified Modeling Language® (UML®), Model-Driven Architecture® (MDA®) and the Business Process Modeling Notation (BPMN®).

BPMN 2.0 Specification

Here is a link to the official specification of the open standard: BPMN 2.0.

Extra Features

Extra features for BPMN are:

  • Import diagrams from Visio
  • Import .bpmn and .xpdl format
  • Make the diagrams interactive
  • A wizard guiding you in creating BPMN Diagrams


Next to BPMN also XPDL is available.

XPDL is a file format to store all details of the BPMN process definition notation in, including graphical descriptions of the diagram, and also executable properties.

In XPDL you store a process in high definition, without any loss, and another product can import it to reproduce it as exactly the same diagram.

Here is a link to the XPDL website.
