Dealing with models with a huge number of elements is a hard process especially when you want to apply some sort of filtration process on element's categories or families. for that i have built a new filter form that can work with all the elements in the model in which you can filter them based on category, family type or family name. Also, the filter form will the ability to control element's viewing process (Isolate, Select, Hide and Unhide) in the active view. The node has been built using Python language and you can run it directly using dynamo player.
You need to install Dyn-BIMHEX package to download the filter.form Node. New update requires to Run the script on the Manual Mode.
