Revit cable tray bend treatment
Cable tray bends in Revit can be efficiently handled using standard elbow fittings, smart bend tools, or pre-made Revit families for precise modeling.
Manual Bend Creation
In Revit, you can create cable tray bends by using standard elbow fittings, typically 45° or 90° angles. This involves placing two straight tray segments and connecting them with the appropriate elbow fitting to achieve the desired bend . This method is straightforward but may require careful alignment and adjustment in 3D views to ensure accuracy.
Smart Bend Tools
For faster and more precise modeling, the GreaterBIM Smart Bend add-in allows you to bend cable trays in multiple directions (up, down, left, right) at standard angles such as 30°, 45°, 60°, and 90° directly in 2D and 3D views. This eliminates the need to cut sections or manually adjust tray segments, saving time and ensuring consistent results . It is particularly useful for MEP engineers, BIM coordinators, and modelers working on complex projects.
Using Revit Families
Many manufacturers provide pre-made Revit families for cable tray bends and fittings. For example:
- Niedax RESK offers versatile cable tray families with customizable dimensions and fittings .
- OBO Bettermann provides Revit families for their cable tray systems, including elbows and accessories .
- BIMsmith Market hosts a wide range of cable tray Revit families for free download, allowing you to select the appropriate fittings and sizes for your project .
Best Practices
- Always use manufacturer-specific families when possible to ensure accurate dimensions and compatibility.
- Maintain consistent angles (e.g., 45° or 90°) to simplify installation and coordination.
- Use smart bend tools for complex routing to reduce manual adjustments and errors.
- Verify bends in 3D views to ensure proper clearance and alignment with other MEP systems. By combining standard fittings, smart tools, and manufacturer Revit families, you can achieve precise, efficient, and realistic cable tray bends in your Revit MEP models.
