ArchiMate Diagrams
The ArchiMate modeling language supports the description, analysis, and visualization of architecture within and across business domains.
iGrafx supports the use of Archimate diagrams with different shape libraries, the ArchiMate diagram type and an Archimate template which contains a reference guide for all the ArchiMate shapes, symbols and lines and their meanings.
Note: Your Admin may have disabled Archimate diagram templates and/or shape libraries. If they did so, then you may not be able to do the following steps.
How to create a new diagram using the ArchiMate template
Create a new diagram using your preferred method (New Diagram button, right-click Tree folder, Add Object, etc.)
In the resulting dialog, make sure Diagram View is selected
Click the Template dropdown menu, then select ArchiMate (if ArchiMate is not an available template, your repository administrator has deactivated the template):
