Covadis 16 Compatibilite Autocad May 2026

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. covadis 16 compatibilite autocad

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. Here’s what they learned over the next three

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.” Marc, a senior topographer at Géomètres du Sud

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, 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.”
