Scratch. Background

Small partners in the revit secondary development, you may need to get all family types in a family environment, then its wave operation

II. Ideas

1. Open the family file. See Note 1
2. Group Manager FamilyManager, referring to note 2
3. Group obtain this family all types FamilyTypeSet, Note 3 reference
4. The operation of all types of aromatic or aliphatic type of a method, see Notes 4,5
5. save, close the document family, see Notes 6 and 7

            Document doc = document.Application.OpenDocumentFile(filePath);

                //6对文档进行保存
                doc.Save();
                //7关闭打开的这个文档
                doc.Close();

IV Notes

In the project environment, or template environment, we are family related operations can be carried out by FamilySymbol, but in a family environment, will be very convenient to use FamilyType
