Any news for setting global parameters?

FAQ

Hi guys,

Until now all topics talking about global parameters is talking about how to read the values of global parameters,

any news on how we can set these values and change them?

Try this code : IN[0] is the name of the global parameter you wish to change and IN[1] is the new value . It should work for all parameter types:

import clr
clr.AddReference('RevitAPI')
from Autodesk.Revit import DB as db

clr.AddReference('RevitServices')
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument

filter =  db.FilteredElementCollector(doc).OfClass(db.GlobalParameter)
gp = [UnwrapElement(p) for p in filter if UnwrapElement(p).Name == IN[0]][0]

#getting the right ParameterValue constructor :
methodname = gp.GetValue().GetType().ToString().rsplit('.',1)[-1]

TransactionManager.Instance.EnsureInTransaction(doc)
try:
	#setting the parameter with the right parametervalue constructor
	gp.SetValue(getattr(db,methodname)(IN[1]))
	out = 'success'
except:
	out = 'failed, check if the parameter value is the right type'

TransactionManager.Instance.TransactionTaskDone()

OUT = out
