1. CONNECT. TRANSFORM. AUTOMATE.
Synchronizing AutoCAD® Map 3D
Enterprise and 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®.
 FME Desktop®was chosen as the solution for
synchronizing the two disparate systems.

3. Synchronization Option 1
 Full Table Comparisons
 UpdateDetector – Custom Transformer
that extends ChangeDetector
 Considerations
 Can take a long time.
 Geometry Comparison can be tricky.
 Attribute precision can create false
positives.
 Establish a trigger or business rule that
time stamps feature edits.
 Used for other portions of the project
but not here.

4. Synchronization Option 2
 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.
 Solution presented here uses this option.

5. FME Desktop®Feature Usage
 SQL Statements and Where clauses
 User Parameters
 Batch Processing and Command Files
 FME_DB_OPERATION Attribute
 Transformers
 Joiner
 TestFilter
 TimeStamper
 FeatureTypeFilter

6. SQL Statements and Where Clauses
 Set long
transaction
current.
 Query inserts,
updates, and
deletes based
on long
transaction
tables.

7. User Parameters
 Accommodate need to run workspaces in batch
mode. Feed parameters at runtime.

8. 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.

9. Finally, the Workspace!

10. 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!
