The following review written by one of the Software Informer contributors applies to version 6.2
Pacestar UML Diagrammer is a cheaper alternative to other popular programs that help programmers, system engineers, or other professionals to create UML diagrams. It comes with a large number of features, as well as customization options and includes all the necessary tools to help users design diagrams for various purposes.
For a beginner, the graphical user-interface of Pacestar UML Diagrammer might seem quite overwhelming. It displays many toolbars and buttons that would make some users think the program is difficult to use. Yet developers that have a lot of experience in UML design will find this program a life saving solution, as its price is considerably smaller than other similar tools.
When I tested the program, I appreciated that it allowed me to customize the graphical style of the nodes by changing color, adding shadows, etc. I was also surprised to see that Pacestar UML Diagrammer comes with many sample diagrams for specific purposes: communications, ticketing, package editing, software deployment, etc.
The program also includes a comprehensive Help manual that offers access to detailed information regarding both UML (Unified Modeling Language) and program features.
I strongly recommend Pacestar UML Diagrammer to any software engineer that needs a tool for software design.
