Hi all,
My end goal is to obtain all unique networks of systems within a project. MEPover has a node Elements in connected network which will find all elements connected to the input element. To get all unique networks, you would need to insert an individual element from each network. (If you know of a way or a node that does this feel free to stop reading and I would love to hear it)
I am trying to modify Elements in connected network from the MEPover package to take a list of all duct elements in the project. The supplied list will contain elements found in the same network, because of this, I am trying to remove all elements from the supplied list as they are found in the network of a previous element.
My python skills still lack a little but I was able to get this to work on a sample script.
elmlist = IN[0]
listout = IN[1]
id1 = []
for i in elmlist:
id1.append(i.Id)
breakcounter = 0
while len(elmlist) > 0:
id2 = []
for i in listout:
for y in i:
id2.append(y.Id)
for e, d in zip (elmlist[:],id1):
if d in id2:
elmlist.remove(e)
id1.remove(d)
breakcounter += 1
if breakcounter == 4:
break
OUT = elmlist
The problem:
The elements are not being removed from my input list like they are in my sample. Essentially I want to take the first item and get all of its connections. I then want to remove all of the connections (this list includes the starting element) from the input list and start over until there are no elements left in the input list.
My additions are running with no errors but it is stuck in an endless loop (if not broken after a forced 4 loops for safety precaution as I am working on it)
elmlist = IN[0]
bool = IN[1]
fullList = []
breakcounter = 0
id1 = []
for i in elmlist:
id1.append(i.Id)
while len(elmlist) > 0:
firstelm = []
firstelm.append(elmlist[0])
if isinstance(firstelm,list):
connector = UnwrapElement(firstelm)
toggle = 0
else:
connector = [UnwrapElement(firstelm)]
toggle = 1
listout = []
if bool:
for x in connector:
lookup = collections.OrderedDict()
collectorWithOwner(x)
listout.append(lookup.Values)
else:
for x in connector:
lookup = collections.OrderedDict()
if x.GetType() == Connector:
ownerId = x.Owner.Id
else:
ownerId = x.Id
collector(x)
listout.append(lookup.Values)
orlist = []
if toggle:
orlist = lookup.Values
else:
orlist = listout
id2 = []
for i in orlist:
for y in i:
id2.append(y.Id)
for e, d in zip (elmlist[:],id1):
if d in id2:
elmlist.remove(e)
id1.remove(d)
fullList.append(orlist)
breakcounter += 1
if breakcounter == 4:
break
OUT = fullList
Here is the original code pulled from MEPover for reference.

Thank you for any help that you can provide.
