Component2 IGetRootComponent2()

Component2^ IGetRootComponent2(); 

Return Value

Because every assembly has at least one configuration, you can use this method to begin traversing an assembly and its components.

This method returns a component object that is, essentially, a launching point for your assembly traversal. It is useful only for calling IComponent2::IGetChildren. Most other IComponent2 object functions do not work with this root component object and return NULL or an error condition. You can call IComponent2::IsRoot to determine if you have the root component.

An IComponent2 object is based on the currently active configuration; one assembly configuration might suppress the component, while another might display it. Therefore, your traversal of IComponent2 objects might vary if you switch to a different configuration.

The order of calls used in a typical assembly traversal is:

1. IConfigurationManager::ActiveConfiguration (called only once)
2. IConfiguration::IGetRootComponent 2(called only once)
3. IComponent2::IGetChildren (called recursively)

From the SolidWorks API, the IConfiguration and IComponent2 objects provide access to all the child components, their transforms, their bodies, as seen in a specific assembly configuration. The component body objects and component transforms can vary based on the configuration; therefore, you should traverse components for each configuration. For example, one assembly configuration might include an assembly-level feature that cuts a hole through each of the components in the assembly.

You can use IComponent2::IGetBody on each assembly component to get the body of each component with the hole feature that was applied in this configuration. If you switch to a configuration without the assembly-level hole and re-traverse the component objects, then IComponent2::IGetBody returns the body object without the hole feature.

SolidWorks generates an IAssemblyDoc RegenNotify event to indicate that a change might have taken place in one of your components. If you receive an IAssemblyDoc RegenNotify event, then you should re-traverse your components to be sure that your information is up-to-date.

If this method is called from the configuration of a part document, SolidWorks returns NULL.

You should use this method of assembly traversal to replace previous calls to the member class.
