Sacramento Area Sewer District (SASD) chose AutoCAD Map 3D Enterprise as their solution for creating and editing their sewer assets. However, their Enterprise GIS is ESRI ArcSDE. Accordingly, they needed a solution for keeping these two disparate systems synchronized. In this presentation, you will learn how FME was used as the synchronization solution.

Synchronizing AutoCAD Map 3D Enterprise and ESRI ArcSDE

  1. 1. CONNECT. TRANSFORM. AUTOMATE. Synchronizing AutoCAD® Map 3D Enterprise with ESRI® ArcSDE® Drew Burgasser, P.E. Vice-President, CAD Masters, Inc.
  2. 2. Summary !  Sacramento Area Sewer District (SASD) chose AutoCAD® Map 3D Enterprise as the front-end GIS application for creating and editing sewer assets. !  However, SASD Enterprise GIS = ESRI® ArcSDE®. !  And, SASD Asset Management = Maximo. !  FME Desktop® was chosen as the solution for synchronizing these disparate systems.
  3. 3. Synchronization Tasks AutoCAD  Map   3D  Enterprise   (Oracle  DBMS)   ESRI  ArcSDE   (Sewer  Data)   ESRI  ArcSDE   (County  Base   Data)   Maximo   Asset   Management   Parcels,Roads, Cities, etc. Sewer Data 1 2 3
  4. 4. Synchronization Task 1 !  Synchronize County Base data. Copy Edits to AutoCAD® Map 3D Enterprise !  What do we have to work with? !  We neither know what has changed and when it has changed !  Not as critical as sewer data. !  Full Table Comparison Required
  5. 5. Synchronization Task 1 !  Solution !  UpdateDetector – Custom Transformer that extends ChangeDetector !  Considerations !  Can take a long time. !  Geometry Comparison can be tricky. !  Attribute precision can create false positives. !  Comparing 100,000 features took minutes. !  Comparing 200,000 features took hours!? !  Split the data into chunks, run multiple workspaces. WorkspaceRunner.
  6. 6. Synchronization Task 1 !  The Workspace… Custom Transformer to calculate AREA and PERIMETER
  7. 7. Synchronization Task 1 !  It would be nice if… !  Feature edits are time stamped via a trigger or business rule. !  No need to compare for edits. !  Editor Tracking easy to turn on for ArcGIS
  8. 8. Synchronization Task 2 !  Edits made in AutoCAD® Map 3D Enterprise must be copied to ESRI® ArcSDE® !  Use Long Transaction Functionality !  Examples !  AutoCAD® Map 3D Jobs !  ESRI® ArcSDE® Versioning !  Using long transaction tables, we can query inserts, deletes, and updates (IDU). !  Very fast. We are only querying the IDU’s in the long transaction. No need to compare: we know what’s changed.
  9. 9. Synchronization Task 2 !  SQL Statements and Where Clauses !  Set long transaction current. !  Query inserts, updates, and deletes based on long transaction tables.
  10. 10. Synchronization Task 2 !  The Workspace…
  11. 11. Synchronization Task 3 !  For new assets, Maximo ASSETID must be copied to AutoCAD Map 3D Enterprise
  12. 12. General Themes !  User Parameters !  Batch Processing and Command Files !  Null Attribute Values!
  13. 13. User Parameters !  Accommodate need to run workspaces in batch mode. Feed parameters at runtime.
  14. 14. Batch Processing and Command Files !  User doesn’t need to open FME Workbench. !  Feed parameters (credentials, server names, db names, job id, SDE version name) via command files. !  Run workspaces in batch mode.
  15. 15. Null Attributes !  Prior to version 2014, FME Desktop® treated null attribute values as non-existent attributes. !  This is problematic for synchronization. If a user sets an attribute value to null, that change will not be synchronized for an updated feature. !  My favorite new feature in FME Desktop® 2014? Null Attribute Support!
  16. 16. Conclusion !  Synchronization !  Good – ChangeDetector !  Better – Use long transactions or editor tracking/ time stamping to query what’s changed !  Use 2014 for null attribute support !  Use command and batch files or FME Server to run your synchronization tasks

  18. 18. Q/A Support: What is AutoCAD® Map 3D Enterprise? !  Product Name Evolution !  Autodesk® TopobaseTM <2011 !  AutoCAD® Map 3D 2012 Enterprise !  AutoCAD® Map 3D 2013/2014 !  Industry Model Functionality !  Enterprise GIS !  Uses FDO in AutoCAD®
  19. 19. Q/A Support: AutoCAD® Map 3D Job Query Examples !  Query Inserted Features !  Query Updated Features
  20. 20. Q/A Support: Key Attribute for Sync !  Key Attribute required in both Systems
