Access Assembly Example (C++ COM)

This example shows how to open, explode and collapse, and create a drawing of an assembly. It also shows how to traverse the FeatureManager design tree, get a component, and suppress and resolve that component. This example uses CComPtr Smart_Pointers.htm and CComBSTR smart types.
