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 with ESRI® ArcSDE®

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.

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. 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. Synchronization Task 1
! The Workspace…
Custom
Transformer
to calculate
AREA and
PERIMETER

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. 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. Synchronization Task 2
! SQL Statements
and Where
Clauses
! Set long
transaction
current.
! Query inserts,
updates, and
deletes based on
long transaction
tables.

10. Synchronization Task 2
! The Workspace…

11. Synchronization Task 3
! For new assets, Maximo ASSETID must be
copied to AutoCAD Map 3D Enterprise

12. General Themes
! User Parameters
! Batch Processing and Command Files
! Null Attribute Values!

13. User Parameters
! Accommodate need to run workspaces in batch
mode. Feed parameters at runtime.

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. 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. 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
