convert type "Inventor.Document" to "Inventor.PartDocument"

[Anonymous]

Hi,

i want to get the ComponetDefinition Object from a Document, but i can get it only from objects with type Inventor.PartDocument. Do I need some type conversion or anything different? VB.net/VBA is also fine for my 🙂

Inventor.Document oDoc = null;
oDoc = _invApp.Documents.Open(fileName, false);

if (oDoc.DocumentType == Inventor.DocumentTypeEnum.kPartDocumentObject)
{
    Inventor.PartDocument oPartDoc = convertToPartDoc(oDoc);
    Inventor.PartComponentDefinition oPartComponentDefinition = oPartDoc.ComponentDefinition;
}

I figured it out! You just need "as".

PartDocument oPartDoc = oDoc as PartDocument;
