: By storing CAD geometry in PostGIS, you can run complex SQL queries that AutoCAD alone cannot perform, such as finding all utility lines within 50 meters of a specific parcel or calculating the total area of rezoned land.
: Unlike static imports, a direct database connection allows for "check-in/check-out" workflows, where edits in AutoCAD can be saved back to the database in real-time.

Integration is rarely "plug and play." It requires middleware. : By storing CAD geometry in PostGIS, you
When importing from AutoCAD, the plugin applies ST_Transform(ST_SetSRID(geom, local_utm), 3857) . This is the #1 source of "it looks right but it's in the wrong county" bugs. Spatial Manager for AutoCAD Basic AutoCAD Users A
Many professionals use QGIS as a "middleware" tool. They load PostGIS data into QGIS, perform necessary spatial cleanup, and then export it to a DXF format for AutoCAD. While this is less "live" than an FDO connection, it is a highly reliable and free workflow. Best Practices for Integration
Here is the breakdown of how these two giants work together, where they fail, and which workflow is actually worth your time.
