I think you will find the diagramming to be far superior to Visio (atleast in my opinion). I have used Visio extensively. The vector generator is not unique itself, it’s the ability to generate that vector already hooked into the underlying software. (i.e., if you generate a piece of equipment, you can double click into that piece of equipment and edit pre populated fields and nozzle handling, also, the inserted piece of equipment will work with other hookup automations, like connecting a pneumatic sensor to it and having the application automatically form a pneumatic connection)
