I want to make a schedule which I can use for ordering components for my project. That means, that I need alle dimensions for every component.

When I have a duct, let's say 500 mm, and I connect another duct, let's say 250 mm, it will make a tap. I need to know that this tap should be a size 500-250, but when I choose the family it's just writing 250-250 under the size properties.

Are there somehow I can change the family or do anything else, so it's possible for me to schedule both size. 500-250 in stead of 250-250?
