Install the program and once installed, open Revit 2023 and go to the Mep Utilities tab. There you can launch the program from the MEP CORE tab menu after using the MEP Utilities Startup button and then the button labeled with the same name as this program. MEP CORE requires that this sub-program be owned and installed to properly be accessible.

For this program, your first step will be setting some options up top and then refreshing the selection list or setting a pre-selection group of items.

Then the program will compile information to build the tree layout.

Once finished you can use the "add" selection to add items you want to select and the "not" selection to specifically remove items that might also end up being collected. ie: selecting floor 3 with "and" and deselecting duct with "not" duct.

Check the tutorial/promo for better explanations on how to use the program if you still need to know more.
