The Electrical Attributes
PropertyManager appears when, while editing a cable route, you query the electrical
attributes of the selected route segment.
To access to the PropertyManager in the flattened route, right-click a route
and select Electrical Attributes.
Select Route Segment / List All Wires
Two options are available to display electrical attributes:
- Select Route Segment
In the graphics area, click a segment of the route to
display its electrical attributes.. The PropertyManager displays the
length and the diameter of the selected segment. The calculation
algorithm for the diameter uses the following formula:
|
D=2*sqrt(A*F/PI)
|
D=Diameter
|
sqrt=Square root
|
A=Area (Sum of the cross section area of
each wire - Area of a circle = PI*r²)
|
F=Correction factor depending on the number
of wires
|

When a cable is in the selected segment, the
calculation considers the diameter of the cable and not the diameter of
the individual cable cores.
The Wire List displays the list of wires, or
cable cores passing through the selected segment.
- List All Wires
The
Wire List displays all the
wires or cable cores.
Show Cross Section opens a dialog box displaying the
cross section of the selected segment.
Wire List
Lists the name of each wire or cable core or those that pass through the
selected segment. The cut length of each wire appears in angle brackets after the
wire name.
Properties and Additional Properties
Lists the property names and values for the selected item in
Wire List.
