How to verify if part is derived

[Anonymous]

I need to check if a part is derived because I'm developing a method to fix missing references.

To verify, I use a foreach that traverses all occurrences.

AssemblyDocument asmDoc = (AssemblyDocument)invApp.ActiveDocument;

ComponentOccurrences Occurrences = asmDoc.ComponentDefinition.Occurrences;

foreach (ComponentOccurrence oOcc in Occurrences)
{


}

In this example, it is possible to see that the reference is lost for the part that originated the derive.

I'm trying to do that, but I can not do it.

PartDocument oPart = (PartDocument)oOcc;

ReferenceComponents oRefsComps = oPart.ComponentDefinition.ReferenceComponents;

DerivedPartComponent oDerPartC = oRefsComps.DerivedPartComponents[1];

DerivedPartDefinition oDerPartDef = oDerPartC.Definition;

if (oDerPartDef is DerivedPartDefinition) {
    MessageBox.Show("yes");
}

Thanks.

Hi marcelo.zattera,

To check for missing references you could try using the methods listed below.

1. To check if the reference is missing:

PartDocument.ComponentDefinition.ReferenceComponents.DerivedPartComponents.Item(1).ReferencedDocumentDescriptor.ReferenceMissing

2. To check if the component is suppressed:

PartDocument.ComponentDefinition.ReferenceComponents.DerivedPartComponents.Item(1).SuppressLinkToFile

3. To check if the component link is broken:

PartDocument.ComponentDefinition.ReferenceComponents.DerivedPartComponents.Item(1).LinkedToFile

Let me know if this helps.

Regards,

Sajith
