I am using Microsoft Visio 2013 to create Process Flow and Block Flow Diagrams (Schematics) of piping systems inside our Plant. I would like to use ArcGIS Schematics with our Enterprise Geodatabase (SQL Server). We are running on 10.2.2. ArcGIS Schematics requires that the data be in a geometric network; I am working with 83 different piping systems (process streams) each requires its own schematic, creating 83 geometric networks is just too cumbersome to manage. Is there a way to use ArcGIS Schematics without a geometric network?
