Specifying

Variant Physical Lengths for a Bundle

You can specify variant physical lengths for a selected bundle to use individual lengths only when a particular option expression is applied to a bundle. For example, when a vehicle topology is identical across its variants except for differences in bundle length.

The physical length is initially determined by the length of the bundle on the diagram. This length is displayed on the General tab in the Edit Properties: Bundle Dialog Box for the bundle and can be overridden (see Specifying the Physical Length of a Bundle). This is the physical length used by default. However, the bundle length may vary for different variants of the built vehicle.

The lengths are passed from Capital Wiring Integrator to Capital Harness Designer when designs are synchronized between the two. Capital Harness Designer uses the variant lengths when performing composite breakdown.

Procedure

1. Right-click the bundle in the Diagram Window or Design Browser (Capital Wiring Integrator) and select Properties.The Edit Properties: Bundle Dialog Box is displayed.

2. Click the Variant Tab (Edit Properties Dialog Box).

3. In the Option Expression column of the currently empty row, enter the option expression for which you want to specify a variant length.A new empty row is added to the table.

4. In the Variant Length column for the option expression that you have entered, specify the variant length.

5. Repeat Steps 3 and 4 for each variant physical length that you want to enter.

6. Click OK to exit the Edit Properties facility and to commit your changes.

Results

• Wiring import and export does not support variant bundle information.

• When the Capital Wiring Integrator design is synchronized with a Capital Harness Designer design, the variant lengths are displayed on the Variant tab in the Edit Bundle dialog box for the appropriate bundle in Capital Harness Designer.

• There is no support for linking variant bundles through Capital Connectors or Change Manager. The MCAD connector is used to set the nominal length.

• When bundles are merged: The bundles retain variants and merge where required.

When merging a variant bundle with a non-variant bundle, the resulting bundle retains the variant information. The lengths for each variant will be modified by adding the default length of the non-variant bundle.

When merging two variant bundles, the variances are merged. Where option expressions match, the variant lengths are added together.

When a variant length is unique on one of the bundles, it is not modified on the merged bundle.

• When splitting a variant bundle, the resulting bundles both have the variant lengths applied. The lengths are adjusted according to the proportional nominal position where the bundle is split.
