The attributes never caught up with the model

Anyone who pulls schedules from models knows this. Geometry and attributes drift apart. A schedule read off the attributes looks complete, right up to the cell nobody updated. You find out when the handhole is in the ground.

One case on our Try page: a handhole schedule from a MicroStation duct bank model. Yesper pulled all 48 structures into Excel, depth read from the 3D geometry. One handhole type is 12 in deeper than its Item Type data says; the detail sheet agrees with the model. The vaults at the road crossing were in 3D only, with no data.

The cell library is fixed before the schedule goes out, and the wrong depth shows up in the schedule instead of the trench. Same for the rest of the Try page: an IFC model of existing catenary masts, a coordinate check on OCS foundations, cable tags against the cable list.
