The Duct Patterns app is a handy tool to help you create the best-looking installation using brass or copper tubing. The app will allow you to set different parameters to help you create the perfect installation, such as the number of divisions, or the end size. You will not need to manually calculate each value. You can also use the app to calculate the length of the middle section, the angle of the bend, and the amount of material you need to create the installation.
