The Family Type Filter is a plugin for Revit 2013 to 2015. I developed it to help my coworker and I, but here it is, uploaded for you for free! It works just like the Category Filter, but with Family Types. No longer do you have to select all family types visible in a scene just to select the types you want. This is an unfinished plugin, there’s no Apply/ReApply functionality, and what you see is all you get – but it does work. Known bug: it will mistaken two different families if their types share the same name. Feel free to contact me if you find any new bugs.
