Welcome to the forums drafterjohn! Where might you be posting from?

10x14x6 pattern?
10" x 14" rectangle x 6" high?
10"Ø x 14"Ø x 6" high?
Need to know more.

I started working in sheetmetal, duct work, over 40 years ago.
A worthwhile and satisfying trade.

All kinds of worthwhile reference material available at The Sheetmetal Shop.

Take a peek-a-boo at the attached *.dwg file.
Lots would depend on sheetmetal gauge and, how do you want to assemble the transition?

If small gauge sheetmetal, easy enough to add 1/2" flanges for spotwelding two pieces together to make the transition.

John:

Added a bit to the sketch (drawing). Sitting here, just watched the Eagles choke again. Ouch.

I didn't note the bend angles, easy enough.
I did add 1/2" flanges for spot welding, again, don't know how you want to secure this transition. I also don't know the gauge you're working with. I am assuming light gauge HVAC ductwork.

The top bends will be over 90°, the bottom (10" x 14") bends will be under 90°.

Comments welcome.

John:

I'll take a peek at your *.pdf sometime today.
At first glance, very nice.

We must also take note, there's always another way to complete the project.
There's always more than one way to complete an AutoCAD layout too!

When you mean "pattern" are you meaning you need to create a flat pattern that will be fed to a plasma or cutter? Or do you just need to represent a transition dimensionally so that a fab shop can produce the transition for you?
