Adding a new item to Mechanical Settings

[Anonymous]

Hi

In "Mechanical Settings", in "Main" I have a item named  "Rectangular Duct:Mitered Elbows/Beveled Taps".

How can I add a new item like "Rectangular Duct:Radius Elbows/Beveled Taps" to it. 

Thanks

Create a new duct type in the families section of the project browser.
