Every Workspace has a Model with a certain set of component types. The name, color, shape or image of these, can be changed to reflect the framework or the way your organization understands the architecture. They can also come straight out of the box by choosing templates when you click on create a new Workspace.
In this example, I chose the template for "Application Portfolio", and this gives me one component type named Application. I can see this when clicking on the menu in the upper right corner and Workspace.
Now I want to change this, so I am clicking on "Manage component types and model" in the menu selection.
Currently, I have one component type, called Application, and it is represented in blue and my shape is the one of an Archimate application component.
I want to change the name, the look and add another component type, check out the video below to see how this is done.
You can also choose images instead of our pre-set shapes and icons, see how to do that here.
After you are done, no need to save, just click on the X in the upper right corner and you have changed your model. This can be updated at any time, and the component with the style you change will change the style.
