How to flip the left and right cable trays

You can flip cable trays by 180 degrees using mirroring techniques, Smart Tray functions, or face-based families in Revit, depending on your workflow and constraints.Using Smart Tray FunctionsIf you are using the Smart Tray add-in, you can flip a straight cable tray by 180 degrees without changing its length. This swaps the first and second ports, allowing you to adjust the tray length from the opposite end. For bends that are upside down, the FLIPTRAYBEND function can correct their orientation while keeping connections intact .Mirroring in RevitIn standard Revit workflows, you can mirror cable trays in a section view. Place the tray normally, then create a reference line in the section and mirror the tray across it. Note that after trimming or copying, the tray may revert to its default orientation, so careful placement and repeated mirroring may be necessary .Face-Based Family ApproachFor more complex rotations, especially when the tray needs to follow a wall or vertical surface, creating a face-based family is effective. This allows the cable tray to attach to any surface and rotate along the height or wall direction. It also ensures proper visibility in electrical discipline views and maintains schedule and tagging capabilities .Additional ToolsThe GreaterBIM Smart Bend add-in allows precise bending of cable trays in all directions (up, down, left, right) at standard angles directly in 2D and 3D views. This can simplify adjustments when flipping trays or correcting bends without cutting sections .SummaryStraight trays: Use Smart Tray flip function or mirror in section view.Bends: Use FLIPTRAYBEND in Smart Tray or Smart Bend add-in.Complex rotations: Consider face-based families for vertical or wall-mounted trays.Check connections: Always verify that ports and bends remain properly connected after flipping. By combining these methods, you can effectively flip left and right cable trays while maintaining proper alignment and connectivity in your model.
