Is this possible for sketchblocks? Can the feature(s) using a sketchblock be found in a similar way using the dependents property? I tried the following but keep getting an error:
Dim oPartDoc As PartDocument = ThisDoc.Document
Dim oPartCompDef As PartComponentDefinition = oPartDoc.ComponentDefinition
Dim oSketchBlockDef As SketchBlockDefinition
For Each oSketchBlockDef In oPartCompDef.SketchBlockDefinitions
For Each oDependent In oSketchBlockDef.Dependents
' ... Error "Object reference not set to an instance of an object."
