If you want to suppress a piece of an assembly, you need to do the following.
1) Cast the main assembly Document object into an AssemblyDocument
2) In the AssemblyDocument.ComponentDefinition object, you'll find an Occurrences property. This is a collection of ComponentOccurrence objects that match up to all the components of the assembly
3) If you know the name of the part you want to suppress (which is what appears in the Model Browser), you can use the Occurrences.ItemByName method. Otherwise, you'll have to loop through the occurrences until you find the one you want. So if you want to suppress the occurrence for "Part1.ipt", do something like this:
{code}
For each objOccurrence as Inventor.ComponentOccurrence in objAssemblyDocument.ComponentDefinition.Occurrences
If Ctype(objOccurrence.Definition.Document, Inventor.Document).DisplayName= "Part1.ipt" Then
objOccurrence.Suppressed = True
Exit For
End If
Next
{code}
A quick note: If you've got any Virtual Components, then the definition's Document property is going to return the Assembly document of the virtual component's parent. You'd want to cast the Definition into a VirtualComponentDefinition object and check its name property instead. You can use "typeof objOccurrence.Definition Is VirtualComponentDefintion" to find this out.
