Hello,
I created a Dynamo script that splits ducts, but when splitting, it does not add a flange between the split ducts.
Could someone help me finish this script? I don’t have much experience with Dynamo, but I’ve divided it so that it first detects if the duct has a height, as I don’t want circular ducts to be selected. Then it filters by size, and so on.
i have a similar script and it does it automaticly. I think you can set it anywhere else, something like auto routing, Ducttype settings regarding connection.

The problem I see with the script Is that It loses connection to other connected elements.
I normally use genius loci split tool and will keep the system, another could be MEPFitting.ByPointsAndCurve from mepover, works great as well…PS your flange family lives in the ductserie----openmep should have nodes as well
Would It be able to see your script on how you used Genius loci?
something here maybe
Thank you very much. I tried using the same method, but the code block doesn’t seem to work. Another question: how would it know where to split? For example, I need it to split every 1500 mm.
Then try as here in line b, 1500..a..1500
no not reallyy…works great here, which revit version are you in ? i think Autodesk.Curve.Length(lst) in your version maybe
try here
Home.dyn (16.3 KB)
I made a change to the code block:
a = Autodesk.Curve.Length(Geometry);
b = 0..a..1500;
It worked like this. I will now try to create a rule so that circular ducts are not cut — then the script will be perfect.
I appreciate your help 
I’m trying to filter rectangular ducts, but when I use List.FilterByBooleanMask with a true/false list, it doesn’t filter correctly. The output is a mix of false and true values.
it shoudnt 
but you will need show us the graph with all nodes pinned…
yeah thats not the best way sort for rect vs round ducts imo.., thats why i just use paramereter exist from clockwork a fast way imo.., but many ways to do that, we could find the shape itself..
I still have the same problem, haha.
I have three ducts—one of them is circular, but it intersects with one circular and one rectangular duct.
isnt that right the output is rect and in is round…not sure i understand then
It’s what it’s supposed to do, but it mixed one of the round ducts into the ‘In’ output.
To clarify, I have 2 rect ducts and one round.
