About Configurable Modules
A configurable module is identified by in the Model Tree. A configurable module is an assembly in a configurable product that supports multiple design variations. Each internal module variant is a unique, independent model that is interchangeable with the other variants in the configurable module. Multiple occurrences of a component are not allowed. A module variant can be a part, a subassembly, or a configurable product. Configurable modules are created in the following ways:
Independently using the New dialog box.
In the context of a high-level configurable product using the Create command.
By saving an existing assembly as a configurable module.
 
* In an assembly with multiple occurrences of a component, only the first occurrence of the component is saved in the configurable module. When a component is patterned, only the pattern leader is saved in the configurable module.
By saving an interchange assembly as a module.
On-the-fly when you transfer a component into a module.
The components in a configurable module are listed under the configurable module in the Model Tree. By default the representative component is first component in the configurable module, but you can set any module variant to be the representative component in an open or active module. The representative component defined in the module is the component used when you place the module, by default it becomes the current module variant after you place the module. The current module variant is the component representing the module in the graphics window and identified by in the Model Tree. You can set any module variant to be current.
When you create a configurable module and add components, each new module variant is added in the default location and represented in an exploded state.
