Can we see all L3 process diagrams (for example) in a large single diagram?
We don't provide a function to create a diagram showing all diagrams of one level. However, you may create a value chain diagram on your own and link all desired diagrams there as collapsed processes. You can find more information about value chains in the user guide: https://docs.signavio.com/userguide/editor/en/modeling_and_notations/value_chains/editing_value_chains.html
Please be aware that there is no function to search for all the processes with a specific level. This is due to the way how the system calculates the process levels. The reason for that can you find in our user guide at: https://docs.signavio.com/userguide/editor/en/portal/pyramid_and_bread_crumb_panel.html?highlight=prozesslevel#calculation-of-hierarchies-paths
If you want to know methods on how to find all diagrams of a specific process level, you may take a look into the following article in our knowledge base:
