Flexible Duct Connection to Ductwork

[StevieD]

Not sure if anyone else has experienced the same problem, but in some instances when I try to connect the flex to solid duct and it is close to the end of the duct, it will connect to the end with a transition, rather than the side. It's starting to pi$$ me off big time by having to increase the duct length, then decrease it, or if it is close to a transition, delete the transition etc etc....

Any suggestions???

Yes, I've noticed this too. I just start further upstream in the duct, and then "bump" it down as far as you like.
I was always taught that it was advisable not to have the spigot right at the very end of the run anyway....helps with air balancing to leave a "pressure boot" at the end, apparently. Maybe 200mm - 300mm?

Thanks Mike....yeah was taught the same.

Even at about 500mm sometimes it wants to connect to the end....arghhhhhh

Yes we leave an air cushion as well at the end of runs 200-300mm. SO I exaggerate my duct length add the end cap and move it closer once done

A Typical Revit Pain this one this!!

I Normally Leave one Flex Gap and it will work OK, if the first Click when drawing Flex is close as possible to to the duct it will also help heaps I find!!
