How to edit the size of a fabrication part Cable Tray
When we add Electrical Cable Tray Fabrication Parts, we are limited to widths of 150, 300, 450, 600, 750, 900 and only one height is available: i.e.
Increase the width and height of the cable tray
Home / Increase the width and height of the cable tray
To change the default size of cable trays in Revit: Go to Manage > MEP Settings > Electrical Settings > Cable Trays > Size. In practice, cable tray dimensions are a system of interrelated measurements —width, depth, length, and material thickness—that directly affect cable fill compliance, heat dissipation, structural loading, and long-term expandability. Ihave successfully modified the fittings families for that but can't do anything about. In this tutorial, I tackle a common issue faced in electrical projects: adjusting cable tray sizes in bulk. I will guide you through the process step-by-step, ensuring you can efficiently modify your cable trays. 5 to 2 metres is standard, but heavier loads or wider trays may require closer intervals.
