Compatibilite Autocad: Covadis 16

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.

Twenty minutes later, the manhole blocks reappeared with their correct invert levels. The terrain model regenerated, showing a 12cm settlement exactly where the pavement later collapsed. The Lambert coordinates snapped back. covadis 16 compatibilite autocad

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. Marc, a senior topographer at Géomètres du Sud

Covadis 16, developed by Géomédia, is a specialized survey and civil engineering add-on that runs on top of AutoCAD. Its compatibility isn’t just about opening files; it’s about preserving . A standard AutoCAD line is dumb. A Covadis 16 “terrain line” knows its slope, its adjacent triangles, and its breakline constraints. Water mains had lost their hydraulic attributes

Covadis 16’s compatibility with AutoCAD is not a switch; it’s a protocol. You can run it on AutoCAD 2024 smoothly—if you respect the migration path. But ignore the wizard, mix proxy graphics with native objects, or open a file in the wrong AutoCAD release, and your intelligent survey data becomes nothing more than colored lines on a ghost layer.

Covadis 16 includes a “Migration Wizard” for files from versions 13-15. Marc had skipped it, assuming newer AutoCAD would brute-force compatibility. It doesn’t work that way. The wizard doesn’t just open the file; it decompiles old Covadis primitives and recompiles them into Covadis 16’s native schema. This is mandatory, not optional.
