When creating content for Revit, parameters are key player to making families what can update and modify easy. Sometimes, actually quite often need to do lots of parameters to make family working certain way. Parameters or creating lots of them are not problem. Actually I like to way how it is quite logical and easy to create even complex families.
But then coming big BUT... when uploading families with lots of parameters to project, all the parameters are visible for users. Most of users doesn't want to see all the parameters of family. For example there is casework family having lots of functionality. To make that family it maybe needs lots of different parameters to control those functionalities and all those "secondary" parameters also appears in project environment. It would be much more user-friendly if can control visibility of parameters in family editor and define what parameters are only visible for users in project environment.
So my wish is, please Autodesk, make parameters to possible to hide in project environment, so users can see only parameters what needed in project environment.
