Use to define the attributes of the cableway branch element.

Description

Enter a description attribute for the cableway branch element.

Function

Enter a function attribute for the cableway branch element.

Purpose

Enter a purpose attribute for the cableway branch element.

Use Material

Select to use the cableway material along the entire cableway branch

Material Type

Use to route the cables correctly dependent upon the cableway type before the tray is dressed with material.

Unset

The routing of the cables are not set or fixed.

Perforated

Cables can be routed through the cableway tray from underneath.

Unperforated

Cables cannot be routed through the cableway tray from underneath.

Beta Angle

Enter the angle for the cableway branch element, default is 0.00.

Use Fixed Bends

Select to use fixed bends when routing the cables on the cableway branch.

Inside Radius

Defines the bend applied to the cableway branch element, once it has been created and dressed, default is 300mm The BRAD attribute is the radius of the RPATH.

Note:
There are two types of inside/outside bends, fixed and variable. The fixed type will have different bend radius for an inside and outside bend. The variable type will have the same radius for both inside and outside bends.

Note:
If a bend is selected that does not match the radius of any bend/riser in the catalog, the application searches for a bend/riser that is as close to the specified BRAD as possible. A Confirm window is displayed, click Yes to accept the nearest match or click No to ensure the branch is dressed with bends/risers that exactly match the BRAD.

If the cableway branch radius is changed, it is reflected on the points of the RPATH. When the justification is set and the cableway branch and radius are modified. The Fradius on the points of the RPATH change accordingly to the justification and direction of the bend and riser.

Open Direction

Enter the direction of the open side of the cableway branch once it is dresses with material, default is U WRT/*.

Justification

The cableway branch can be justified in both the horizontal and vertical planes, select the justification from the pull-down menu, default is Bottom - Center.

  • Bottom - Center

  • Bottom - Left

  • Bottom - Right

  • Center - Center

  • Center Left

  • Center - Right

  • Top - Center

  • Top - Left

  • Top - Right

If the justification is modified after dressing, the material is aligned automatically with the volume. However some material can overlap and some gaps between cable trays can appear. Therefore the branch should be redressed after a change on justification.

Max Cables

Define the maximum number of cables on the cableway branch.

Minimum Layers

Define the minimum number of layers on the cableway branch, the default is 1.

Cable Layout

Define how the cables are routed on the cableway branch. The position of the first cable on the cableway is defined as listed below, further cables are routed away from it in the direction from Head to Tail.

  • Left

  • Left - Center

  • Center

  • Right - Center

  • Right

  • Unset

Cable Excess

Define how much of an allowance for sagging (when the cable is supported in the cableway branch) is required, default is 0.

Maximum Fill

Define the maximum fill level on the cableway branch (the software automatically calculates this value based on the horizontal fill (width of the tray) and the total width of the cables on the tray and all gaps included depending on the properties of the cable).

Current Fill Level (%)

Displays the current fill level of the cableway branch element.

Allowable Classes

Positions multiple cable classes routed along a particular segment on a cableway branch. Segments can be added and/or removed.

Volume

Defines the volume size the cableway branch will occupy in the 3D model.

Shape

Defines the shape of the volume in the 3D model, select Rectangular or Circular. Enter the cableway branch volume dimensions. A graphical representation of the dimensions can be viewed in the Cableway Branch Volume Dimensions window.

Click show volume dimension sketch to display the Cableway Branch Volume Dimensions window.

Connections

Use the connections functionality to position and connect a cableway head and tail.

Defines how the cableway branch head and tail are positioned and connected. By using the coordinates manually entered, an offset or by a location picked from the 3D view. These coordinates can then be locked.

Connect From

Explicit

East, North and Up - (default) positions the branch head using the coordinates manually entered, using an offset from the 3D view.

Head of Cableway Branch

Positions the branch head at the head of an existing cableway branch. When prompted, Pick CWBRAN in the 3D view at the position of the existing branch head.

Tail of Cableway Branch

Positions the branch head at the tail of an existing cableway branch. When prompted, Pick CWBRAN in the 3D view at the position of the existing cableway branch tail.

Branch Off

Positions the branch head at a selected point on a existing branch.

When prompted, Pick on the segment from which the branch should connect: to identify the segment.

Route Attachment Point

Positions the branch head at the position of a selected route attachment point. When prompted Pick ATTA in the 3D view.

Junction Box/Pull Pit

Positions the branch head to a junction box or pull pit. When prompted Pick P Point of Junction Box or Pull Pit (Distance[0]) Snap: in the 3D view.

Note:
Once the Create Cableway Branch link label is selected, the HCREF and TCREF attributes are set and the branch is created.

Pick Head Position

When prompted, Pick to define position (Distance [0]) Snap: in the 3D view. Once selected, this will be used as the position for the new cableway branch head.

To lock the cableway branch head coordinates, click to check the Lock checkboxes.

Moving the cableway branch a specified distance in a particular direction can be done by entering the required coordinate values and using the Lock checkboxes before creating the cableway branch.

Alternatively, if the cableway branch has been created, select the branch and move it into the desired position using the Model Editor.

Copy Tail Position

The coordinates of the tail are copied and these are populated in the window.

Note:
In the case of Branch Tail, the functionality available is Copy Head Position.

Offset

Use to position the branch head explicitly, at the head/tail of the cableway branch, branch off or route attachment point using an offset.

Branch Tail

The functionality available for selection from Branch Tail is identical to that previously described in Branch Head.

Create Orthogonal Route and Direction Sequence

Use to constrain the cableway branch to an orthogonal route and define the direction that the route takes orthogonally.

Note:
The Direction Sequence and the Open Directory are compatible (for example - an open direction of U could be invalid if the Direction of Sequence was set to U-N-E or U-E-N).

Upon creation, the cableway branch is displayed in the 3D view automatically routed along an orthogonal path connecting the head and tail positions.

For further information, refer to Cableway Branch and Editor.
