[revitworkbench]

Hi, I am having touble creating a duct transition it keeps coming in backwards and then failing. Please have a look and let me know if you can figure out what I am missing. Thanks!

i tried to draw a duct on that
you have round duct and rec. duct

draw a section and draw them from the section

note that the duct connection (round) is made on the lower ring not on the top of the ring

I was building it on the wrong axis. I built it facing left/right and it worked perfectly. Thanks!
