Navigate to Zone 101C-CABLEWAYS, located in Site CABLE in the Design Explorer. Create a new cable tray /CTRAY_YY012
The Head position is at X 9000mm, Y 3500mm, Z 15500mm and the Tail position at X 9000mm, Y-3000mm, Z 14250mm.
The cable tray width is 600mm from the Head and 450mm for the Tail.
Use the Quick Cable Tray routing and the cable tray modification Handle to produce the following cable tray layout.
5.5.6 Positioning Using Ships Reference
The Position - Ship References form is a tracking form which means when the user navigates to an element, the form automatically updates itself to the current databases element, showing its position both in terms of the ship reference and in terms of absolute position XYZ. The form allows the user to specify the position of the elements in the design. Changing either shows the new position of the object in the 3D graphics window using an encapsulating box, the system also updates boxes to reflect the new position.
Frame, Lg(Horz), Lg(Vert) Defines the position of the element either with respect to the ships reference gridlines with an offset or as an absolute value (World Position).
Reset Resets the form to the current database position of the element. i.e.
it reverts back to its original position on the database.
Apply Modify the selected elements to the defined position. If the value is incorrect then use the Undo icon on the main menu toolbar.
Use the cabletray YY012 created in Exercise 4. Indicate the component that requires re-positioning ELBO 1), now select Position > Using Ship References from the main pull down menu. The Position ± Ship Reference form appears,
L
Where an element has no position attribute or the user does not have the correct access, or the element is locked, the form will be inactiveL
The form can be docked but initially it appears undockedA bounding box is added to the component and the origin P0 is highlighted. In the Position ± Ships References form change the LH (Horz) Y position to 2000mm. The bounding box is repositioned, and the LH position in the form is updated.
If the new position is acceptable then click the Apply button.

Moving Inline Components to another part within the same Branch
Inline components that have not been connected to another branch can be moved into another part of the cable tray so long as it is within the same branch.Note that Feature Highlighting should be toggled to Off to allow components to be moved to other legs of the branch. Feature Highlighting is toggled on and off by pressing the F key on the keyboard. The current status of Feature Highlighting can be checked in Selection > Feature Highlighting
Use the cabletray created in Exercise 4. Select the inline component (TEE 1) to reposition, then click the Model Editor icon from the Model Editor Toolbar and the Cable Tray Component Modification handle now appears on the component to move.
If Feature Highlighting was enabled, only the leg the component was currently located in would be highlighted, and the component could only be moved within the constraints of this leg, as shown above.
With Feature Highlighting disabled, all legs of the branch are highlighted and are available for the component to be moved to, as shown below.
Select the Cable Tray Component Modification handle and drag the inline component to its new position.

Select the cable tray component modification rotational handle with the left mouse button held and drag the component rotational handle to the required angle.
5.5.9 Orientate a Component to a Point
Move the cursor over the components modification handle and right click, from the pop-up select Orient To Point. Now move the cursor over the P points of the other components, when the orientation is correct select the P-point.
5.5.10 Align a Component with a Direction
Move the cursor over the components modification handle and right click, from the pop-up select Align with Direction. Now move the cursor over the P points of the other components, the directional plane will be highlighted and the component will be aligned, when the Alignment is correct select the P-point.
5.5.11 Align with a Direction Relative to a Axis
Move the cursor over the components modification handle and right click, from the pop-up select Align with. The Enter Direction For Z Axis form appears, key in Y 45 Z and then click the Preview button. If the preview is correct then click the OK button, if not enter another direction and repeat process.

5.5.12 Rotate by Entering a Value
Move the cursor over the components modification handle and right click, from the pop-up select Enter Value, the Rotate Selection about U form appears, key in the rotational value required, in this case key in 45 and then click the Preview button. If the preview is correct then click the OK button, if not enter another value and repeat process.
5.5.13 Move an Elbow / Bend in One Direction
With Model Editor active, pick the Bend as show. The cabletray modification handles are displayed on the component.
As the cursor is moved over the cable tray modification handles, the axis line is highlighted. Move the cursor over the required axis for the direction the elbow needs to be moved, then right click and from the pop-up select Enter Value. The Move Selection form now appears, key in the move value and click Preview. If the preview is correct then click OK
5.5.14 Move an Elbow / Bend in Two Directions
Move the cursor over the two lines forming a plane for the D[LV¶VLH;=<=DQGVW on the cable tray modification handles. 7KHD[LV¶VOLQHVDUHKLJKOLJKWHG0RYHWKHFXUVRU

be moved, then right click and from the pop-up select Enter Values. The Move Selection form now appears, key in the move values and click Preview. If the preview is correct then click OK
5.5.15 Move an Elbow / Bend Using the Align with Feature
As the cursor is moved over the cable tray modification handles, the axis line is highlighted. Move the cursor over the required axis, then right click and from the pop-up select Align with Feature. A directional arrow appears, move the cursor over another P-point that the elbow needs to be aligned with. When the correct P-point is identified, select it and the elbow will be aligned with the P-point.

6 Fixed Length Trays and Implied Straights
Implied straights in cable trays can be compared with implied tubing for piping. Implied straights occur where there is a physical distance between consecutive list order components. Implied straights can be replaced by fixed length tray (FTUB) elements.
6.1 Replacing Implied Straights with Fixed-Length Trays
Fixed-length tray (FTUB) elements can be applied to all or part of the current branch in the model. Creating fixed length trays will replace sections of implied straights.
To create fixed length trays the user must be at branch level or below in the design hierarchy. Selecting Modify > Fill from the pull down menu will open the Fill Cable Tray Branch form.
The Fill options list allows the user to select the extent of the cable tray branch that fixed length trays will be applied to. Four options are available to the user:
Branch Replaces all implied straights with fixed length trays for the entire branch.
Components Inserts fixed length trays between two specified components.
Head to Component Inserts fixed length trays between the branch head and a specified component.
Component to Tail Inserts fixed length trays between a specified component and the branch tail.
Model with Implied Straights Model with Fixed Trays Applied to Branch The fixed-length trays used are derived from the current branch specification. The number of trays used in each location is calculated from the length of the implied straight which they replace.
6.2 Replacing Fixed-Length Trays with Implied Straights
In design, it may be necessary to remove fixed-length tray (FTUB) elements from all or part of the current branch in the model. To remove fixed length trays the user must be at branch level or below in the design hierarchy. Selecting Modify > Unfill from the pull down menu will open the Unfill Cable Tray Branch form.
The Unfill options list allows the user to select the extent of the cable tray branch that fixed length trays will be removed from. Four options are available to the user:
Branch Removes all fixed length trays and replaces them with implied straights along the entire branch.
Components Removes fixed length trays between two specified components and replaces them with implied straights.
Head to Component Removes fixed length trays between the branch head and a specified component and replaces them with implied straights.
Component to Tail Removes fixed length trays between a specified component and the branch tail and replaces them with implied straights.
