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.

Marc closed AutoCAD 2024. He reopened the file using the dedicated (which forces the correct AutoCAD version profile). He ran the Migration Wizard on the 2018 drawing, selecting “Full conversion with attribute preservation.”

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.

Lena now has a sticky note on her monitor: “Covadis 16 is backwards compatible. Your workflow is not.”

Here’s what they learned over the next three hours, and what every firm should know:

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.

The 2018 file wasn’t broken. It was frozen in time . Covadis 16, running on AutoCAD 2024, could see the ghost of the old data but couldn’t wake it up without a migration sequence.
