Does a Component Definition have data from other Component Definitions?

[prashanth9690]

I am using C++ SDK.
I want to get all the component definitions from a model and save the mesh data.
Then, when I render the full model, I want to refer from the already parsed component definitions data (rather than creating mesh data everytime from component instance).

I am doing this,
SUComponentDefinitionGetEntities(ComponentDefinition, &ComponentEntities);
then get face data from ComponentEntities.(Is this enough?)
What I want to know is, Is it possible that a Component Definition is made from multiple component definitions (basically, a component definition is nested)?

Yes, INSTANCES of other definitions can be nested inside definitions (and usually are.)

Also Groups can be nested inside components and visa versa. (Groups are special kind of component instances that are hidden from the component definition manager.)
