Autocad: Covadis 16 Compatibilite

Marc, a senior topographer at Géomètres du Sud , opened the file in AutoCAD 2024. The drawing loaded, but something was wrong. Manholes appeared as generic circles instead of the precise blocks he expected. Water mains had lost their hydraulic attributes. And the coordinate system? It had defaulted back to World UTM, ignoring the local Lambert projection.

Covadis 16 saves natively to AutoCAD 2018 DWG format by default. If you open that file in AutoCAD 2024 without Covadis loaded, you’ll see everything—but the intelligence is gone. To preserve intelligence, you must use the “Save as Covadis” command, not AutoCAD’s native save. covadis 16 compatibilite autocad
