Revit should provide a function for password protecting parameters in families. It seems like sending models that contains an electronic seal (most finished models do) is dangerous. With BIM 360, we are sharing the model with our clients weekly. It is too tedious to go in and add/remove the seal every single time. It would be nice to have a yes/no parameter that shows/hides an image (the seal and signature) in a symbol family, and can only be checked or unchecked with a password. Furthermore this would help protect electronic seals and signatures in general, giving the capability for the family to display the seal/signature/date only to the owner of the seal.
Password protected parameters would also be useful in general, not just for this application.
