Automating Revit family types creation using Dyanamo and Excel data

Creating Revit Family Types from Excel Spreadsheet.  We use Excel data to create more family types. We read all the parameters like name, width, height, etc. and then create new family types and writes the parameters to them. When we need to create a lot of family types that is how we eliminate the errors while creating new types. Since the manufacturers often has such spreadsheets it is easy to just read the information from them automatically and write back to Revit.
