Unlike regular SOLIDWORKS API, Document Manager doesn’t provide a specific interface for the assembly document rather it should be managed by ISwDMDocument and ISwDMConfiguration2 interfaces.

Some of the methods in those interfaces are exclusive to assembly document only, e.g ISwDMConfiguration2::GetComponents or ISwDMDocument8::GetComponentCount.

It is recommended to use ISwDMDocument::FullName SOLIDWORKS Document Manager API to get the full path and match its extension to .sldasm to validate that document is an assembly.

This section contains examples and macros related to working with assembly documents using Document Manager.
