Develop GIS automated process with Arc. GIS Model. Builder Select the project and adjacent features August 14, 2009 Copyright Brandywine CAD Design, Inc 2009

Develop GIS automated process with Arc. GIS Model. Builder Add CAD Fields August 14, 2009 Copyright Brandywine CAD Design, Inc 2009

Develop GIS automated process with Arc. GIS Model. Builder Export features and annotation to Auto. CAD August 14, 2009 Copyright Brandywine CAD Design, Inc 2009

Compare times to create selected features and text n Create from scratch in Auto. CAD n Insert orthophoto as background image n Draw road centerlines n Type road names n Type extension and plan numbers n Insert FH block for each fire hydrant n Look up hydrant average pressure (PSI) in AIMS n Type hydrant ID, plan and PSI for each hydrant Time: August 14, 2009 46 minutes Copyright Brandywine CAD Design, Inc 2009

Compare times to create selected features and text n Use GIS automated process n Open Export_to_CAD GIS project n Execute Select_Project model n Turn on hydrant, roads, and extension labels n Convert labels to annotation n Execute Add_CAD_Fields model n Execute Export_to_CAD model Time: August 14, 2009 3 minutes Copyright Brandywine CAD Design, Inc 2009

Conclusions n The estimated average time saved per project will be 50 minutes n The estimated annual time savings will be 100 man/hours August 14, 2009 Copyright Brandywine CAD Design, Inc 2009

Other Benefits n CAD staff benefits from GIS without the need to learn GIS n Stimulates discussion for future GIS projects targeting data exchange between GIS and Auto. CAD August 14, 2009 Copyright Brandywine CAD Design, Inc 2009
