Get system type of pipe

Developers

Hi,

I struggle to get the System Type of pipes. A pipe will have three related values in this context:

  1. System Type Name, e.g. “Raw water”
  2. System classification, e.g. “Domestic cold water”
  3. A unique name consisting of system type name + integer, e.g. “Raw water 1”

I want the first value. I am able to get the other two by following code:

e.MEPSystem.Name      # gives "Raw water 1"

pipingSystems = FilteredElementCollector(doc).OfClass(PipingSystemType).ToElements()
list_piping_system = [ ]
list_piping_system_id = [ ]

for i in pipingSystems:
	list_piping_system.append(i)
	list_piping_system_id.append(i.Id)

for k, sys in enumerate(list_piping_system_id):
	if sys = e.get_Parameter(BuiltInParameter.RBS_PIPING_SYSTEM_TYPE_PARAM).AsElementId():
		list_piping_system[k]       # gives an element with name "Raw water"

I’m currently using the dynamo node “Element.Name” to get the value “Raw water”, but I would like to to this in python. But if I add the attribute “.Name” after the element, I get an error saying “Attribute error: Name”

Hi,

Add .ToDSType(True) to your script.

doc.GetElement(e.get_Parameter(BuiltInParameter.RBS_PIPING_SYSTEM_TYPE_PARAM).AsElementId()).ToDSType(True).Name

Awesome, thanks!

Had to modify it slightly, though, here is the code that worked:

for k, sys in enumerate(list_piping_system_id):
	if sys = e.get_Parameter(BuiltInParameter.RBS_PIPING_SYSTEM_TYPE_PARAM).AsElementId():
		list_piping_system[k].ToDSType(True).Name

why is this not doing it for all revit system families like Pipes, Ducts, Flex Pipes, Conduits, Cable Trays and only Pipes and Ducts?

hi dont think conduit and cabletray have any systemtype

how can I get the System Type parameter value as string with python? I do not achieve this I do not know why

i saw in revit api RBS_CABLETRAYCONDUIT_SYSTEM_TYPE

Yes but dont thinnk thats a parameter i guess…

in this case maybe can retrieve the information from the connectors of the families, they will tell you what system?
