A CAD cable tray type identifier is a classification or code used in CAD software to specify the material, shape, size, and configuration of a cable tray for design and modeling purposes.

Overview

In CAD systems, cable trays are represented as predefined blocks or 3D models that include information about their type, material, and dimensions. These identifiers help engineers and designers select the correct tray for electrical routing, ensuring compatibility with project specifications and other infrastructure elements .

Common CAD Cable Tray Types

Cable trays are typically classified by:

• Material: Aluminum, steel, stainless steel, or fiberglass .
• Shape/Profile: Ladder, perforated, solid-bottom, or wire mesh.
• Size/Width: Standard widths and depths to accommodate different cable loads.
• Bends and Branches: Identifiers may include angle types, offsets, and junctions for routing .

CAD File Formats

Cable tray types are available in multiple CAD formats for interoperability:

• AutoCAD: DWG, DXF for 2D and 3D modeling .
• Revit: RVT files for BIM integration .
• Neutral 3D formats: STEP, IGES, STL for cross-platform use .
• Bentley DGN: For infrastructure projects using Bentley software .

Using Type Identifiers in CAD

1. Select the tray type based on material, shape, and size.
2. Assign the identifier in the CAD library or project database.
3. Apply routing preferences such as elevation, alignment, and bend types .
4. Model in 3D to ensure proper coordination with other systems and avoid clashes .
