Revit will only allow dimensions to be placed on the center line of Fabrication containment parts.
This isn't the way cable trays, ladders & baskets are set out on a working drawing.
Dimensions need to be from the outer edge, not the center (native cable trays within Revit allow this).
So we like to be able to place dimension from the outer edge.
- Fabrication containment part. only dimensions possible from the center of the Ladder or Cable Tray.
- native cable tray with dimension from the edge.
