Managing Floorplans with AutoCAD and ArcGIS Using FMESteve Grisé – Vertex3

University of Washington (Seattle)
20+ million square feet of floor space Growth: 1400 to 1700 floors in the past 3 years Capital Projects Office contracts and manages
construction After construction facilities are handed over to
Facilities Management Use FME to stitch together 1700+ dwg files into a
seamless Esri Geodatabase

Inside the Skin of the Buildings
Demo
Load a few drawings 1125 02,B1,03
Data Flow
Floorplan Drawings
Autodesk Vault/Mirror
ETL Geodatabase
Challenges
Large number of drawings Original Arcpy script never completed
Ran for as long as a day before … Need to make sure that incremental update
process will never result in “missing” floors/rooms Processing somewhat simplified through ArcGIS
for AutoCAD
Logic
Windows process scans the vault mirror every hour and looks for new drawings
Xml config file(s) drives most of the process
GDB versions used for transactional update
Main function is python without arcpy Arcpy subprocesses FME subprocesses
Full run completes in ~28 hours
Processing Logic
For each drawing Create a version Make a feature view Delete existing records for layers/floor Call FME as a subprocess to insert new data If everything worked:
Rec and post version Else:
Delete version
Later Additions
Easier Xml config Add layers and processes Parallel processing
Simplified script logic Needed a lobotomy…
Graphical challenges Self-intersections Catwalks Arch multi-part lines for faster display Floor polygons
Trends
Simple approach for smaller campuses/new users MSC feature classes/attributes Geoprocessing/FME options
More sophisticated tools for advanced users and non-MSC data/attributes FME +
Cloud Tribal campus networks and associated
performance
