When I try to size the ducts I see this in most of my fittings....
The element (of type Duct Fittings) has a connector with a fitting joint mismatch (at connector #1). The connections are not the same size.
Can someone help plz?
Solved! Go to Solution.
Check your elevations for the taps compared to the main. Sometimes if they are not exactly the same I get mismatches.
Thanks buddy...it works when main and branches are rectangular...but when I use rectangular mitered elbows/tees as my main branch and round ducts taps with dampers as my branches I see this error after sizing the duct run...It is where the round takeoff with standoff damper connects to the main duct..photo attached
I think Branch and Main should be same, I mean if you are using Rectangular mitered elbows/tees as main, You have to use branches also the same. Check once.
Hello and welcome to the Discussion Groups!
Would you be able to post a sample of your Project file? The file may very well be too large to post here (even if just a tiny, purged sample) so if you have difficulties, send me a Private Message and I shall send you my email address, if you wish. That way, I can take a look at your specific situation.
What do the ducts/connectrors look like when viewed as a close-up 3D view? I find that for 90% of my problems, viewing them in 3D, I can see what is happening. The other 10% percent, I get upset, throw my computer in the middle of the freeway and watch tractor trrailers run over it. Just kidding, The other 10% remains unknown, and well - life is too short - I align them (without connecting) and move on. Time is money and sometimes sitting there trying to figure out why Revit does what it does, can mean a small chunk of change for the company, and for us - the contractor will not see the 3D view - only 2D. They will build from 2D and use their experience to make the connections. We can't give them *every* fitting. We have to allow them to think for themselves.
Corey- please give me your personal email address....Although I deleted and purged everything it is still 6.4 MB and can't be attached here
Rick- great advice mate..the 3D view looks fine though
I have received your Project file via private means.
How are you going about connecting the branch duct into the mains? Are you placing the taps manually? In your Project file, I see the warning you are referring to, except mine reports "...(at connector #2)..."
If I selected the branch duct, grabbed the connector grip towards the main-side, and then dragged it to connect to the duct main, it reconnected seemingly correctly and the auto-size seems to function without further errors.
Thanks COrey..The thing I sent you with those errors is the output of Revit auto routing using the ducts sizing tool!
A stupid question
when I select the fitiings I cant see the connectors to drag them and attach them to the main duct...I even tried copyong it but still no connector!
The other wierd thing is when I move the connector both main and branch duct moves which means that they are connected but the error is still there!
Also the air flows add up to the main duct which again means the system is connected!
Pelase leave the duct check system on to see all the errors.
