How can I read revit family properties before loading it into Revit.exe

[Anonymous]

Hi, I'm a software engineer at Architecture Design Firm in Dubai. I'm developing revit add-ins for their production team. I would like to know is this possible to extract revit family properties (Type and Isntance) before loading it into the Revit 2017.exe. I did some research and wrote the following code. However, on debugging doc.IsFamilyDocument returns false.

public static void FamilyTransaction(Document doc, string FamilyPath, out Family family)
        {
            // Load family from file:
            using (Transaction tx = new Transaction(doc))
            {
                tx.Start("Load Family");
                doc.LoadFamily(FamilyPath, out family);
                
                if (doc.IsFamilyDocument)
                {
                    FamilyManager familyManager = doc.FamilyManager;

                    // get types in family
                    string types = "Family Types: ";
                    FamilyTypeSet familyTypes = familyManager.Types;
                    FamilyTypeSetIterator familyTypesItor = familyTypes.ForwardIterator();
                    familyTypesItor.Reset();
                    while (familyTypesItor.MoveNext())
                    {
                        FamilyType familyType = familyTypesItor.Current as FamilyType;
                        types += "\n" + familyType.Name;
                    }
                    TaskDialog.Show("Revit", types);
                }


                tx.Commit();
            }

 I'm new into the Revit API, maybe I'm doing it wrong way. Would appreciate any help. Thank you.

Hi!

You are loading family to your open document (family or project). You need to open document instead:

var famDoc = application.OpenDocumentFile(familyPath);

Another option is to extract and analyze part atom (xml) from your family using Application.ExtractPartAtomFromFamilyFile method
