Covadis 16 Compatibilite Autocad May 2026

That word— should —is the most dangerous word in civil engineering.

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. covadis 16 compatibilite autocad

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. That word— should —is the most dangerous word

Lena ran a diagnostic using Covadis 16’s “Audit de Dessin” tool. The results flashed red: “34 Covadis 14 objects detected. 12 orphaned attributes. 1 corrupted terrain model reference.” A standard AutoCAD line is dumb

The collapse on Avenue Victor Hugo was repaired the next day. The cause? A forgotten 2018 utility trench, poorly backfilled. The data had been there all along—frozen, silent, incompatible.

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

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.
