Get Rectangular, Oval and Round Size from Duct Settings

Revit
1

Hi all, it’s possible to collect Rectangular, Oval and Round Size from Duct Settings from the active document with the three colums “Size”, “Used in Size List” and “Used in Sizing” ?
Actually I can only collect DuctSettings and GetDuctSizeSettings

Thanks in advance

clr.AddReference('RevitAPIUI')

fec_DuctSettings = FilteredElementCollector(doc).OfClass(DuctSettings).ToElements()
GetDuctSizeSettings=DuctSizeSettings.GetDuctSizeSettings(doc)

OUT=fec_DuctSettings,[GetDuctSizeSettings]

Hi @paris

Is this what you want?
DuctSettings

Hi @Kulkul thank you for your answer, great! it’s exaclty what I’m looking for,
can you explain a bit more what methods/property are you used?
Cheers

Thanks @Kulkul how translate “foreach( KeyValuePair<DuctShape, DuctSizes> pair
in settings )” into python?
Cheers

for sizes in GetDuctSizeSettings:
	for s in sizes.Value:
    #Continue your code here to extract....

And also refer to .NET Dictionary class:

Thank-you @Kulkul I’ll try your suggestion.

Hi @Kulkul thanks for your link, I can now get the values, but this type of dictionary it’s actually over my head :slight_smile:
Have a good day.
Cheers

Here is an alternative with nested Python dictionaries to find properties for one size

import clr
import System
import re
clr.AddReference("RevitAPI")
import Autodesk
from Autodesk.Revit.DB import *
from Autodesk.Revit.DB.Mechanical import *
from Autodesk.Revit.DB.Plumbing import *

clr.AddReference('RevitServices')
from RevitServices.Persistence import DocumentManager
doc = DocumentManager.Instance.CurrentDBDocument
uiapp = DocumentManager.Instance.CurrentUIApplication
uidoc = uiapp.ActiveUIDocument
app = uiapp.Application
sdkNumber = int(app.VersionNumber)

getDuctSizeSettings = DuctSizeSettings.GetDuctSizeSettings(doc)

def convertDiamValue(mepSize):
	value = mepSize.NominalDiameter
	if sdkNumber < 2021:
		value = UnitFormatUtils.Format(doc.GetUnits(), UnitType.UT_HVAC_DuctSize, value, False, True)
		return value
		
	else:
		value = UnitFormatUtils.Format(doc.GetUnits(), SpecTypeId.DuctSize , value, True)
		return value 

typeStr = IN[0]
sizeStr = IN[1]

mepSizeDict = {}
iterator =  getDuctSizeSettings.GetDuctSizeSettingIterator()
while iterator.MoveNext():
	pairValues = iterator.Current
	keyName = pairValues.Key.ToString()
	values = pairValues.Value
	# get all properties
	firstObjet = list(values)[0]
	getprops = clr.GetClrType(firstObjet.GetType()).GetProperties()
	#
	mepSizeDict[keyName] = {convertDiamValue( x) : {p.Name : p.GetValue(x) for p in getprops if re.search(r'Diameter', p.Name) is None} for x in values}

OUT = mepSizeDict.get(typeStr).get(sizeStr)

Hi @c.poupin great! Thank you for your reply, I’ll try to learn and modify your python code to find the way to create a dictionary like @Kulkul.
Have a good day
Cheers

Hi Paris, output looks great. could you please provide the dynamo script?
