How to hide cable trays in CAD

You can hide cable trays in CAD by adjusting display settings, using dynamic blocks, or editing display representations in AutoCAD MEP.Using Display Settings in AutoCAD MEPIn AutoCAD MEP, you can control the visibility of cable trays through the MEP Display Control. For example, you can set a B-GAP Width in the options to completely hide a cable tray that overlaps with another, or adjust the style to make it appear grayed or dashed for clarity when multiple trays cross each other . This is useful for managing complex 3D models without deleting objects.Editing Display RepresentationsTo hide cable tray annotations or the trays themselves in plan views:Go to the Manage tab and open Display Manager.Expand the Sets tree and select the current display set (e.g., MEP Design - Plan).In the Display Representation Control tab, locate Cable Tray in the object list.Right-click the checkbox for the plan display and select Edit.Turn OFF the Annotation display or adjust visibility settings as needed and click OK . This ensures that cable trays or their annotations do not appear by default in your template drawings.Using Dynamic BlocksDynamic blocks can also help manage visibility in 2D CAD drawings. You can create a dynamic block for a cable tray with properties to show/hide, stretch, move, or rotate the geometry. This allows you to toggle the visibility of specific trays without affecting the rest of the model .Additional TipsEnsure cable trays do not overlap or partially duplicate, as this can cause display issues or extra segments in 3D models .Use the Cut tool to split cable trays into separate pieces if you need to hide only a portion of a tray .For pre-made layouts, you can insert CAD blocks of cable trays and control their visibility by layer management or block properties . By combining these methods—display settings, display manager edits, and dynamic blocks—you can effectively hide or manage cable trays in both 2D and 3D CAD models.
