In Enterprise Architect Version 14, Sparx Systems added functionality to simplify the process of creating neat and tidy diagrams. This tutorial highlights the "Neaten" and "Auto Route" functions, which are a handy means of tidying diagrams.
The Neaten function brings elements together based on proximity and optimized alignment. Try it out on your next diagram via Layout > Tools > Diagram Layout > Neaten.
The Auto Route function tidies the connectors on a diagram, automatically neatening up lines and re-routing them to avoid overlap, where feasible. See, Layout > Tools > Diagram Layout > Auto Route.
To learn more about diagram layout tools in Enterprise Architect, take a look at the Building Models in Enterprise Architect Guidebook, which covers more functions like Neaten and Auto Route.
