Add roomnumbers to pipes

Revit

Hi there all

I am trying to add roomnumbers to all of my ventilation components, but I am stuck at pipes and ducts, beacuse the graph I use for, for instance Airterminals searches for elements in room… I am assuming, for this to succeed, I need to divide my pipes into curvesegments, so that I can search for these curve points in rooms.
So here is my Attempt for now, where I have reused my graph for locating airterminals in rooms:

tilknytning%20af%20rum%20til%20pipes%20og%20ducts
tilknytning af rum til pipes og ducts.png4002×1820 338 KB

But I don’t know what I am doing wrong, because when I try to divide my pipes into curves, it does not return any values…?

tilknytning%20af%20rum%20til%20pipes%20og%20ducts%202
tilknytning af rum til pipes og ducts 2.png1128×742 210 KB

But what I am trying to do afterwards is locate the rooms, at these points from the curves, whereafter, I am going to sort the results, so that I only get one instance of each room, I then want to write back to the pipe.

Can anyone help me…?

Hi,

Have you already seen this ?

Hi,

There are probably several ways to collect pipes in linked rooms, but but I did it with the BoundingBoxIntersectsFilter method.

I modified the node “Tool.GetSurroundingElements”
from SteamNodes package to work with linked document.

	host.append(UnwrapElement(i))
for i in IN[1]:
	finst.append(UnwrapElement(i))
for i in IN[1]:
	finstID.append(UnwrapElement(i).Id)	


superset=[]
hloop=[]


for h in host:
	collection = List[ElementId](finstID)
	collector=FilteredElementCollector(doc,collection)
	a=h.BoundingBox[activeV]
	c=Outline (a.Min,a.Max)
	d=BoundingBoxIntersectsFilter(c,float(IN[2]))
	e=collector.WherePasses(d).ToElements()
	setlist=[]
	hostlist=[]
	hostlist.append(h)
	setlist.append(e)
	all_lists = [hostlist,setlist]
	c=reduce(operator.add, all_lists)
	superset.append(c)
		
OUT=superset

!! There are several lacings and levels to set on the nodes.

Holy cr…! I think I need to learn some code… :smiley:

Thank you so much Alban!
