The first thing to consider when using the Cable Tray application is the specification you are currently using as default.
The following exercises will illustrate different means of cable tray routing by giving examples of many of the situations you will encounter.
The following worked example demonstrates how to build up the cable tray component sequence illustrated below. It assumes that you have already set your default specification to SCTG.

BRANCH /TRAY-1/B1 showing input sequence Figure 1
Create> Zone
Create the hierarchy in which the Cable tray is to be routed.
Press OK
Create> Main
Press OK,
A Create Cable Tray Branch form is shown automatically
When you select OK, a Branch at Explicit Position
form is shown.
Connect>Branch
Position each end of Branch to its termination point (HEAD & TAIL)
Input these values to start the branch at the upper penetration of the east wall at the south corner named
/EASTHOLE1. Select Apply and then Dismiss the form.
This form allows the HEAD and TAIL connections to be specified.
On dismissal, a “dotted” line appears in the graphical view joining the HEAD and TAILAVEVA Plant (12 Series) Cable Tray Modelling TM-1102

Create>Component
We will now choose a Tee that will be connected to the HEAD automatically and then repositioned.
Press the Create button
Fig 1 (Tray Ref. 1) Because the Default button on the Cable Tray
Components form is not set, you will be shown a form giving the available tee options. Pick one and press
OK.
If your Choose form does not have the component description set, modify the choose options.
To do this use:
Settings>Choose Options then select ALL
Set the open tray direction to U.
The Tee will be positioned at the start of the branch (head) because the Auto Connect button is ticked.
Position the Tee using Through ID Cursor from the
Create Cable Tray Components form and select the penetration in the floor near the centre of the south wall named /FLOORHOLE1.
Create another Tee in the same way as above and position it through the next penetration named
/FLOORHOLE2.
Fig 1 (Tray Ref 2) Create a Bend from the Cable Tray Components List.
The Bend will be connected to the previous Tee because Auto Conn has been switched ON.
The Cable Tray Components form will now be left on display until the entire Cable Tray has been routed.

Position the Bend through the penetration in the wallnamed /INTHOLE1.
The leave side of the Bend should point “North”. If it doesn't use
Orientate>Component>Change Exit
The Bend’s direction should be facing North, as shown in Fig 1
Create a Riser and select the OR 90 type (90 deg. elbow outside radius), and position it a Distance 5000
and the leave should automatically point down.
Create another Riser and select the IR 90 type (90 deg. elbow inside radius), and use Through ID Cursor
to position it through the penetration named /INTHOLE2. The leave should automatically point North
Create a Bend using the Cable Tray Components
form and select the RH 45 deg. ANGLE type. Position it a Distance 5000 from the previous component.
Create another Bend and select the LH 45 deg. ANGLE type.
Position this using the Position>Component>Plane Through.
Select a Plane E and Through ID Cursor and pick the penetration in the wall named /INTHOLE3.
Dismiss this form.

Next, Create a Bend and select the RH 90 deg.ANGLE type.
Use Through ID Cursor to position it through the penetration named /INTHOLE4
Fig 1 (Tray ref. 8) Create a Tee and select the type with PBOR3 600.
Position the Tee using Through ID Cursor from the
Create Cable Tray Components form and select the penetration in the floor near the centre of the north wall named /FLOORHOLE3.
Fig 1 (Tray ref. 9)
Create a Reducer and select the type PBOR1 450 CONC. Position it a distance 2500 from the previous component.
The tray we are now creating is 450mm wide.Create a Bend from the Cable Tray Components form and select the LH 45 deg. ANGLE type. Leave it connected to the previous component.
Fig 1 (Tray ref. 11) Create another Bend from the Cable Tray Components
List and select the RH 45 deg. ANGLE type.
Position this using the Position>Component>Plane Through.
Select a plane N and Through ID Cursor and pick the penetration in the wall named /INTHOLE5. Dismiss
this form.
Create a Tee and select the type with PBOR3 450. Position the Tee using Through ID Cursor from the
Create Cable Tray Components form and select the penetration in the floor near the centre of the north wall named /FLOORHOLE4.

Create another Tee as above. Position the Teeusing Through ID Cursor from the Create Cable Tray Components form and select the
penetration in the floor near the centre of the north wall named /FLOORHOLE5.
The connection point of the tee should point south but if it points north, change this using
Orientate>Component>Swap Branch.
Fig 1 (Tray ref. 14) Create another Riser and select the OR 90 type
(90 deg. elbow outside radius).
Use Through ID Cursor to position it through the penetration named /FLOORHOLE6. The leave should automatically point Down.
Fig 1 (Tray ref. 15) To complete the Cable Tray the Tail needs to be
positioned at the penetration named
/FLOORHOLE6.
Select Connect>Branch. This will position the Tail at the P-leave of the last member.
This will set Tail attributes TBOR, TPOS, TCON and TDIR.To position the Tail at the penetration named
/FLOORHOLE6 select Position>Branch>Move Through.
The Branch is almost finished apart from it has not been filled.
To fill the Branch select Modify>Fill.. and select
OK.
You cannot fill a Pipe, only a Branch.If you have made a mistake during your design, it is best to Unfill, do the modification and then Fill
