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.
That word— should —is the most dangerous word in civil engineering.
“The 2018 file was made with Covadis 15,” his junior technician, Lena, said, peering over his shoulder. “We’re on Covadis 16 now, with AutoCAD 2024. It should work. Should. ”
