Specifying Variant Physical Lengths for a Bundle

You can specify variant physical lengths for a selected bundle. The individual lengths are used only when a particular option expression or functional variant module code is applied to a bundle. You may want to do this 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 in the diagram. This length displays on the General tab of the Edit Properties 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 Systems Integrator to Capital Harness Designer and Capital Harness Designer Modular when designs are synchronized between the two. Capital Harness Designer uses the variant lengths when performing composite breakdown.

Note

The physical Variant Length is different to the nominal Length of the bundle (specified on the General tab of the Edit Properties Dialog Box for a bundle). The nominal length is calculated from the graphical length of the bundle, although you can override it. It is used to calculate the length of the wires that pass through the bundle. The variant lengths are not used to calculate wire lengths in Capital Systems Integrator and Synthesizing Wiring does not create a separate wire for each variant.

Procedure

Right-click the bundle in the Design Browser (Design tab) or Diagram Window and choose Properties; the Edit Properties Dialog Box displays.
Click the Variant tab.
In the Variant Expression column of the currently empty row, enter the option expression or functional variant module code for which you want to specify a variant length; a new empty row is added to the table.
In the Variant Length column for the option expression/functional variant module code that you have entered, specify the variant length.
Repeat steps 3 and 4 for each variant physical length that you want to enter.
Click OK to exit the Edit Properties dialog box and to commit your changes.

Results

Composite Wiring Synthesis and Modular Wiring Synthesis synthesize a single wire regardless of the number of variant lengths specified in the table. The wire length uses the graphical or overridden bundle length from the General tab of the Edit Properties dialog box.
Wiring import and export does not support variant bundle information.
When the Capital Systems Integrator design is synchronized with a Capital Harness Designer or Capital Harness Designer Modular design, the variant lengths display on the Variant tab of the Edit Bundle dialog box for the appropriate bundle in those applications.
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 are 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.
