Get pipes with certain direction

[til.shviger]

hi,
how can I get pipes with a certain direction of flow? Is this possible?

[Yna_Db]

Can you please refer to what you have tried so far and/or to related posts such as this one?

Reading direction property of connectors on ducts/pipes

Seems to be working fine for me: in the picture below the open end of the labeled duct, shows ‘false’ in my script indicating it’s the open end on the duct and the corresponding index for the direction is set to ‘In’ which is also correct. [image] Maybe you could show some more of your work and show us where things are going wrong for you.

#Назначьте вывод переменной OUT.
list_ps=[]
list_fs=[]
list_elbow=[]
list_tee=[]
list_z=[]

#filter pipes
list_ps=[i for i in IN[0] if i.GetCategory.Name=="Трубы"] 
#filter pipes fittings
list_fs=[i for i in IN[0] if i.GetCategory.Name=="Соединительные детали трубопроводов"]     


       
#get intersectioon fittings with pipes
for k in list_fs:
	for j in list_ps:
		if k.BoundingBox.Intersects(j.BoundingBox)==True:
			sublist= [k, j]        
			list_z.append(sublist) 
lst=sorted(list_z, key=lambda x: x[0] )

#Sort pipes from fittings
 
ps = dict()
for x in lst:
    p = x[0]
    if p in ps:
        ps[p].append(x[1])
    else:
        ps[p] = [x[1]]
result = sorted([v for k,v in ps.items()], key = lambda x: x[0])
 
# elbow and tee lists
#for i in result:
#    if i.Count==2:
#        list_elbow.append(i)
#    else:
#        list_tee.append(i)
#

OUT = result

and this simple pipes

im just get pipes which is connected to individual tee (later ill use many branches of pipes but now its just simle example)

and im want to get in different lists the pipes in green frame and red frame

may be use the degrees between pipes: 0 degress or 90 degress for example…
and better : if we now flow direction (how vectors orientation for example) then we can filter pipes with similar direction

and main : im want to do this in python (or used minimum count of code blocks)

Filter duct on orientation

Hello all, I have been working on my own ‘tag all’ function. I just wish to be able to filter the input of elements. First: I wish to be able to filter on length. I got this working my self. Second: I wish to filter on orientation. I want to be able to do this for tag position. i want to place tags as seen below: [image] So basicly i need to filter the list below for my element input, just no idea where to start… (basicly i wish to say: if a duct has a line for wich the start and end point …

@til.shviger It would help if you could upload a small Revit file with few pipes.

@Vikram_Subbaiah , are you haven’t found a solution for my question ?

[Vikram_Subbaiah]

@til.shviger I can foresee inadequacies in the example below, but hopefully it will help direct you

@Vikram_Subbaiah
thank you!
Can you explain me how works the node Vector.Normalized? why we are use it?

[Vikram_Subbaiah]

Vector.Normalized gives us the corresponding unit vectors and enables comparison
The origin of all normalized vectors is the origin and magnitude is 1.
