About Schematics
ArcGIS Schematics is an ArcGIS Desktop extension that allows rapid checking of network connectivity. It lets you quickly understand network architecture and shortens the decision-making cycle by presenting synthetic and focused views of the network.
ArcGIS Schematics gives organizations a proven return on investment in diagram generation (automatic generation versus computer-aided design [CAD]).
