Previously, I explained how to create a Dynamo script that calculates the weight of rectangular ducts. You can view that script at the following link: https://dynamoscripts.com/rectangular-duct-weight/
This script calculates the weight of round ducts. Before running the script, the user should create a Project Parameter (as shown in the video) with the name “Duct Weight”. Then, after running the script, that parameter will be populated with weight values.
Before you start using this script, please back up the existing project model.
Also, if you wish to download this (and all other scripts) along with my sample files, please visit the Shop page.
The script does not use Dynamo packages.
