This task explains how to
create a wire group reference. A wire group is an electrical object
representing a multiconductor cable, for example a twisted pair. It may
contain wires and/or wire groups, themselves containing wires and/or wire
groups. |
|
Wire group reference can be created by aggregating:
built-in wires or wire groups (as manufactured for example) or wire
references/wire group references from catalogs.
Wire groups can be stored in catalog, using the
dedicated command.
It is possible to import/export wire groups specifications
from/to ECAD (using CAA API or XML files). |
|
Open a new product document. |
|
-
Click
Define Wire Group
.
You are prompted to select the root product
-
Select Product1.
The dialog box opens: |
|
-
Specify the parameters of
interest:
-
Enter a value in the
Part Number
field
-
Enter a value in
Type field: it
can be Generic or Shielded.
- Generic is the standard value
- Shielded: two extremities (ElecWireGroupExtremities)
are published.
This makes it possible to prepare ground connection (ground
return) for further use.
|
-
Enter a value in the
Sub Type
field, if needed
-
Enter a string in the
Color
field, if needed
-
Enter a value in the
Diameter
field
-
Enter a value in the
Wire Length Coefficient field:
It is a real, greater than/equal to 1 (default value is 1)
It takes into account the wire twisting to compute the wire length:
Wire Length = Wire Group Length x Wire Length Coefficient.
-
Enter a value in the
Bend Radius
field.
You can then add wires or
wire groups. |
-
Click Add Wire
The dialog box opens: |
|
-
Specify the parameters of
interest:
-
Enter a value in the
Part Number field
-
Enter a value in the
Section field
or
-
Enter a value in the
Diameter field
-
Enter a value in the
Bend Radius
field
-
Enter a string in the
Color field
-
Enter the Number
of wires you want to create using these attributes.
|
|
- If you enter a value in Section, the Diameter
is computed and vice-versa.
- According to the last parameter entered, the other one is
computed using knowledgeware.
|
-
Click Add Wire Group.
Repeat step 3,
a to g.
-
Click OK to
validate.
|
Creating Wire Groups From Catalogs
|
|
-
Click
Define Wire Group
.
You are prompted to select the root product
-
Select Product1.
The dialog box opens: |
|
-
Click OK to validate.
-
Click Catalog Browser
and open CatalogOfWires.catalog for example.
The full path is: .../online/elbug_C2/samples/CatalogOfWires.catalog. |
|
-
Double-click Power wires:
the folder content is displayed.
-
Select wire1, drag
and drop it onto the Product1 in the specification tree.
|
The wire is added to the wire group. |
|
This also applies to add wire group from catalog to a wire group. |
-
Close the Catalog Browser.
|
|
Remember:
- A wire group reference is defined in a CATProduct document.
- The selected product must be the root product.
- A wire group may contain other wire groups and/or wires.
- A wire group has no visualization
- A wire group only has extremities if it is shielded (those
extremities will be used in further release for grounding purpose). For
the time being, the ground connection will not be managed so the
Shielded wire group will have the behavior as the Generic
one.
- A wire group can only be created from wire references and not from
wires already instantiated.
