Model

A representation of a major vehicle variation. Each model defines an allowable combination of all the variant options and also limits the options that are applicable to each major vehicle variation.

Examples might be “US, LHD, 3 liter” and “UK, RHD, 1.2”.

In a project, you define a set of models in a Basic Plan that you can then associate with one or more Capital Systems Integrator designs. You can have multiple plans, and therefore multiple sets of models, in a project. In addition, you can export a plan from one Capital Systems Integrator project and import it into another, if the options used in the plan are available in the target project.

When you define a model, you specify a set of possible combinations of variant options, options and option combinations that could be in a vehicle. For example, electric windows and a 4-speaker or 6-speaker stereo system.

You can then set which model you want to use in a vehicle configuration. This restricts the harness levels that you can use for each harness in the vehicle configuration.

If variant options are not defined, a single model is sufficient for a plan.

The Capital definitions of STD and OPT options in a model are not always the same as those used within OEMs and their suppliers:

• STD - an option marked as STD is always included in the vehicle and cannot be removed or switched for a different feature.

• OPT - an option marked as OPT may or may not be included in the vehicle. Composite Wiring Synthesis considers all allowable combinations of OPT options.

In particular, note that a STD option is not a feature that is included in the base model but may be exchanged for another feature. In Capital, such a feature would be modeled as an OPT option since it may or may not be in a vehicle.

For an example of vehicle models in a project, see Examples of Composite Data.
