Hi there
I would like to know if there a way to create new wire sizes material with nodes in Dynamo.
Best Regards
I don’t have an immediate answer but have you been able to create a list of these parameters in the dynamo environment. This would be my first attempt to try to solve
Looks like you can add them manually but I am unsure if dynamo will be able to talk/control this deep into REVIT.
Interested to know the answer if you get there.
As far I go, I just realize that i need how to create a new element type, because the three ones in the list of the node “All elements of type” are the one that came manual in Revit, i think if we create another wire type in that list, we can now manipulate all the parameters. I do not know if I am wrong or not.
Hello,
i’m not sure if there is a node for this
you can try this method with Python
import clr
import sys
import System
#import Revit API
clr.AddReference('RevitAPI')
import Autodesk
from Autodesk.Revit.DB import *
import Autodesk.Revit.DB as DB
from Autodesk.Revit.DB.Electrical import *
clr.AddReference('RevitAPIUI')
from Autodesk.Revit.UI import *
clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.Elements)
clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
doc = DocumentManager.Instance.CurrentDBDocument
wiretype = UnwrapElement(IN[0])
strSize = IN[1]
ampacity = IN[2]
diameter = IN[3] * 0.00328084 # convert to decimal feet
error = None
tempRating = wiretype.TemperatureRating
wireMaterial = wiretype.WireMaterial
TransactionManager.Instance.EnsureInTransaction(doc)
try:
newSize = tempRating.AddWireSize(strSize, ampacity, diameter)
except:
error = "Error, this ampacity or size already exists for :\nTemperatureRating : {}\nWireMaterialType : {}".format(tempRating.ToDSType(True).Name,
wireMaterial.ToDSType(True).Name)
TaskDialog.Show("Error Size", error)
TransactionManager.Instance.TransactionTaskDone()
if error is not None:
OUT = error
else:
OUT = 'Success', newSize

Hi Thank you for the help. I do not know if I am doing right because prompts me "Warning: Get.ValueAtIndex operation filed " in the code block
hi,
in your code bock replace List.clean by List.Clean
filters = wireType.Name == "THWN" ? wireType : null;
out = List.Clean(filters, false)[0];
Oh I see yeah you right, now my filter works but on the python node says
btw, thank you for your help
the error indicates that the Size is already existing (script launched twice?) verify in your electrical settings
I figure out what was the problem, I need to remove the existing one on my particular material which in this case is copper, now works fine thank you very much.
Hi @c.poupin with the code that you share it!. I was trying to looping, instead of make 1 by 1. put all together.
import clr
import sys
import System
#import Revit API
clr.AddReference('RevitAPI')
import Autodesk
from Autodesk.Revit.DB import *
import Autodesk.Revit.DB as DB
from Autodesk.Revit.DB.Electrical import *
clr.AddReference('RevitAPIUI')
from Autodesk.Revit.UI import *
clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.Elements)
clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
doc = DocumentManager.Instance.CurrentDBDocument
wiretype = UnwrapElement(IN[0])
strSize = IN[1]
ampacity = IN[2]
diameter = IN[3] * 0.00328084 # convert to decimal feet
Newiresize=[]
error = None
tempRating = wiretype.TemperatureRating
wireMaterial = wiretype.WireMaterial
TransactionManager.Instance.EnsureInTransaction(doc)
for wiretypes in wiretype:
try:
wirety = wireypes + 1
newSize = tempRating.AddWireSize(strSize, ampacity, diameter)
except:
error = "Error, this ampacity or size already exists for :\nTemperatureRating : {}\nWireMaterialType : {}".format(tempRating.ToDSType(True).Name,
wireMaterial.ToDSType(True).Name)
TaskDialog.Show("Error Size", error)
Newiresize.append(newSize)
TransactionManager.Instance.TransactionTaskDone()
if error is not None:
OUT = error
else:
OUT = 'Success', newSize, Newiresize
but I got a warning
Try to learn the basics of python, the basics are not difficult.
While waiting to try this
import clr
import sys
import System
#import Revit API
clr.AddReference('RevitAPI')
import Autodesk
from Autodesk.Revit.DB import *
import Autodesk.Revit.DB as DB
from Autodesk.Revit.DB.Electrical import *
clr.AddReference('RevitAPIUI')
from Autodesk.Revit.UI import *
clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.Elements)
clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
doc = DocumentManager.Instance.CurrentDBDocument
toList = lambda x : x if hasattr(x, '__iter__') else [x]
wiretype = UnwrapElement(IN[0])
strSizes = toList(IN[1])
ampacitys = toList(IN[2])
diameters = [d * 0.00328084 for d in toList(IN[3])]# convert to decimal feet
result = []
tempRating = wiretype.TemperatureRating
wireMaterial = wiretype.WireMaterial
TransactionManager.Instance.EnsureInTransaction(doc)
for strSize, ampacity, diameter in zip(strSizes, ampacitys,diameters):
try:
newSize = tempRating.AddWireSize(strSize, ampacity, diameter)
result.append(newSize)
except:
error = "Error, this ampacity or size already exists for :\nTemperatureRating : {}\nWireMaterialType : {}".format(tempRating.ToDSType(True).Name,
wireMaterial.ToDSType(True).Name)
result.append(error)
TransactionManager.Instance.TransactionTaskDone()
OUT = result
Thank you very much @c.poupin, I would like to learn more about Revit Api docs, specially the Autodesk.Revit.DB.Electrical any advice that you could give me It will be great.
