Hello,
I began with schematic extension... then sorry if my question seems stupid. 
I would like to find an automatic way (ArcToolBox/Arcpy) to remove deleted entities from an existing schema.
I saw the "UpdateDiagram_schematics" function but I don't see any option to do that.
Here is the workflow (schema is already created) :
1) Start a edit session on geographic feature class
2) Remove geographical entities
... How to remove corresponding schematics entities?
Thanks,
Flavie
