All we would need is the plan view (looking at it from the top) and the desired length.

The layout process is the same whether there's an offset or not.
A plan view and the length is all that's needed.
What size duct and offset are we talking about?

Let's say it's 10/8 to 6 inch round. The 10/8 would kick up 3 inches and to the right 2 inches to line up

A sketch with the 6" circle superimposed over the 8x10 rectangle at the required offset is all that is needed (along with the length).
It doesn't even have to be to scale, as long as the offsets are clearly marked.

We normally label either top or bottom, up or down and arrow in the direction.
With your drawing you wouldn't know if the top or bottom is up 3" . Or you can also do a side view with the plan view.
