When a seed file is created from a model file, it contains all of the information from the mdb and csd file. Therefore, if you want to use the seed file to only save items such as color coding, model options, graph settings, etc., based on an existing model but not the actual elements, you should remove all elements from the existing model, save it under a new name, and make that the basis for a seed file. Otherwise the new model file created from the seed file will just be a copy of the prior model file.
