To access a specific component in an assembly you'll need to traverse
through the entire assembly. There are two other alternatives that I think
will accomplish what you want. Since you're editing a part or subassembly,
you probably really don't care about obtaining a specific occurrence, but
just the document that an occurrence references. Assuming you have the
filename of the file you want to edit, you can instead traverse through the
FileReferences of the assembly. The program will be similar to traversing
through the occurrences, but will not need to traverse through so many
objects. For example, if I have an assembly that contains two plates and
one hundred sets of bolts and nuts, the occurrence count is 202, while the
file reference count is 4. This is because all of the bolt occurrences are
referencing the same file, and the same with the nut occurrences.
The other option, and the simplest, is to just iterate through the open
documents using the Application.Documents object. This provides access to
all documents currently open within Inventor. Even those that were opened
as a result of being referenced within another document.
