The script gives you the ability to show a critical path in any view.
When the user runs the script the UI will ask for the System name. The user can choose only one system name and after that, the script will find the critical path and color elements that belong to the critical path.
Fittings do not carry Section parameter that is why fittings will not have override color. When you run the script for the second time override from the previous run will automatically reset.
Please make sure that before you start using this script that you back up your existing project model.
Also, if you want to download this (and all other scripts) with my sample files please visit the Shop page.
The script uses the following Dynamo packages: Clockwork v.2.3.0 Data-Shapes v.2019.2.42
