Introduction
Your progress
Cable tray routing is an important activity on any large project. It uses the same principles and concepts as pipe routing.
The aim of the course is to provide the skills required to use the Cable Tray Design application in the most productive way.

The training set up tool is an additional tool installed along with the training material for the exclusive use of training purposes. It is designed to
automatically build the training project data required for the completion of the "Cable Tray Modelling" training course.
The following video will show how to enter an AVEVA Everything3D session and apply the Cable Tray Training setup on the provided training project.

Creating a Cable Tray
Creating a Cable Tray
Your progress
There is a separate design hierarchy for cable tray routing which follows the same principles as for pipe routing; i.e. each cable tray element may own a number of branches. In turn, branches may own a number of tray components like bends, risers and reducers.
The following video will build the appropriate hierarchy and then create a Cable Tray Branch, and add a single component at the Branch Head.

Exercise - Creating a Cable Tray
Your progress
Prior to creating a cable tray the correct hierarchy must be present in the Model Explorer. Navigate to the SITE-CABLE-AREA03 level and then create a new ZONE named ZONE-CTRAY-CONTROL-AREA03.
Add SITE-STRUCTURAL-AREA03 to the 3D view.
Create the Cable Tray Main CTRAY-AREA03-CONTROL and set the specification to VANTRUNK-SW5-SS.
Position the Head W 288500mm, N 311000mm, U 104310mm and the Tail W 288500.0mm, N 289000.0mm, U104310.0mm.
Set the width as 600mm for the Head and 450mm for the Tail and the Direction to S for the Head and N for the Tail.
Set the Connection to Open for both Head and Tail.
Create a Tee component by working forward from the Head position. Ensure the Auto
Connect check box is selected then add a 600.00mm bore 300.00mm bend radius Tee
to the head of the branch. Set the tray direction to U. The branch should look like this in ISO 1:

Positioning Commands
Positioning Commands
Your progress
To position branch Head/Tails relatively, select the branch within Model
Tray tab to display the Move Branch form. This form allows the user to
position the Head/Tail in various
ways, Distance, Through, Clearance and Towards.

Copy a Branch
Copy a Branch
Many cable tray networks make use of components being regularly repeated in standard configurations. As such, it is desirable for designers to be able to copy parts of the cable tray network and position them elsewhere in the model. This can be achieved by copying a complete branch and moving it to another position.
The following video will copy Branch CTRAY-AREA03-POWER/B2 using the Copy Offset feature.

Data Consistency
Data Consistency
Your progress
If Isodraft is to be used to produce isometric plot files of cable trays there are a number of points that the user must consider.
The cable tray must be data consistency checked and any errors removed before an isometric plot is generated.
Any Branches that make up a cable tray must connect to the Main Branch. It is not possible to have a branch off a branch, as this will cause ISODRAFT to fail.
The following video will connect all the Branches created in this course and then run a Data Consistency Check on the ZONE.
The following video launches E3D 2.1, opens the Isodraft module and creates Isometric drawings for the POWER and CONTROL Cable Tray systems.
