You only use subsystems in the Standard Interface. You can either create new subsystems or read in
existing ones. When you create a new subsystem, you must reference an existing template. When you use
an existing subsystem, the template associated with it is automatically read in.
Subsystems are based on templates and allow standard users to change the parametric data of the template
as well as the definition of some of the components. For example, you can change the location of
hardpoints and modify parameter variables.
The template-based products organize the basic components that make up a full assembly or subassembly
into subsystems. For example, subsystems can include suspensions, wheels, drivelines, chassis, and so
Subsystems contain descriptions of the component that they model. These descriptions consist of:
• Design data, such as wheel radii, toe angles, and locations of various points in the subsystems,
named hardpoints, mass properties of parts, and so on.
• References to property files that contain design data for bushings, bumpstops, dampers, engines,
springs, and tires. A bushing property file, for example, contains a description of the bushing's
stiffness and damping characteristics.
• Reference to a template that defines the subsystem's construction, including the kinds of parts
and how the parts interact and attach to one another. For example, a template that defines a rack
and pinion steering system defines a rack part, a pinion part, and a housing part. It also defines
that the rack slides in the housing, that the pinion rotates in the housing, and that the rack and
pinion are geared together. Since the construction of all rack and pinion steering systems is
similar, all subsystems describing a rack and pinion steering system can reference the same
