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

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.

Default square to round detail

Typical drafting is to show both a plan and side view, (either first or third elevation). Depending on the metals workers interpretation of 1st and third elevation view, better to show side view by arrows.
