We have internal software EPDS/Cable manager used for calculating length of cable and cable tray.
This works based on Node XYZ coordinates values.
Following are the steps use to determine length from 3D model in REVIT.(Refer attached Image)
- Draw cable tray route in 3D model (Tray route shown in green color).
- Marks nodes at bends, junction and straight run.
- Each node marked with unique tag number sequentially (ex: 0001 to 0159).
- Each of these nodes will have XYZ coordinate, those coordinate will exported to excel sheet using schedules/Quantities.
