Connection between vertical MEP elements (pipes and ducts)

[Alberto Z]

Hi everyone,

I am handling the clash detection of a project in which MEP models are divided by disciplines and by floor ( Mec-1st, Mec-2nd… Plu-1st, Plu-2nd… etc.).
So I would like to check if the connection between vertical distribution elements at different floors is correct (red vs. magenta in the picture below).

I tried with Rule 222 but, without applying restrictions to the rule, I obviously get thousands of errors.
I can not understand how to exclude all the other elements from the rule checking and focus only on the right ones.

Thanks in advance!

Hi! You can try to use Rule 23 - find components uder vertical segments of upper levels.
Vertical segments you can choose by create classificator.
First way - by size of Bounding box (input Quantities. Bounding box height more than max duct width and you will filter all vertical segments lenght of which is more than duct width
Second way - by distance from level. Suppose, than ducts are mostly near the top of ceiling, so all ducts with Location.Global Bottom Elevation near Level (+/- 200 мм) are segments, which go from downer level.
Could be exeptions, but it will narrow your search

@Konstantin thank you so much for your answer!
I finally had time to “test” your suggestion (second way) and it works quite good! The IFCs I have are not properly well done, so the rule works so and so, but I understood the idea behind and it is super!
Thanks again!
