Revit Family Parameters Value "Family Editor"

Someone @Kulkul @craig @Einar_Raknes could write the final code for reading the parameter value. Because i’m trying this and of course returns me the parameter name, not the value:

import clr

# Import RevitAPI
clr.AddReference("RevitAPI")
from Autodesk.Revit.DB import FamilyManager

# Import DocumentManager and TransactionManager
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument

pl = doc.FamilyManager.Parameters

Name_Parameter = IN[0]
for p in pl:
	a = p.Definition.Name
	if a == Name_Parameter:
		OUT = p.Definition.Name

Thanks a lot Kulkul, the solution is working for number parameters!

@Kulkul the solutions is not working for text parameter. You know why this could happen?

Hi @Raul.Galdran ,

this should handle all parameter types :

import clr

# Import RevitAPI
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import FamilyManager

# Import DocumentManager and TransactionManager
clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager


doc = DocumentManager.Instance.CurrentDBDocument
s = doc.FamilyManager.CurrentType

pl = doc.FamilyManager.Parameters

Name_Parameter = IN[0]

p = [i for i in pl if i.Definition.Name == Name_Parameter][0]

try:
	v = s.AsString(p)
except:
	try :
		v = s.AsValueString(p)
	except :
		try:
			v = s.AsDouble(p)
		except:
			v = s.AsInteger(p)

OUT = v

I tried your code and at least for me doesn’t work with Length Parameters:

The one up is yours. And the one down is mine, yesterday i managed to find a way. Still needs a little bit of work so it can read all type of parameter but at least can read text and length parameters. I’ll like also integer and number but i think is just adding a little bit more of code.

i copy the final code, is a little bit bungler but works:

import clr

# Import RevitAPI
clr.AddReference("RevitAPI")
from Autodesk.Revit.DB import *

# Import DocumentManager and TransactionManager
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument

pl = doc.FamilyManager.Parameters
s = doc.FamilyManager.CurrentType

mm=304.8
Name_Parameter = IN[0]

for p in pl:
	a = p.Definition.Name
	if a == Name_Parameter:
	
		paramType = p.Definition.ParameterType
		if paramType.ToString() == "Length":
			OUT = s.AsDouble(p)*mm
		else:
			OUT = s.AsString(p)

Thanks all for your ideas and your time

My bad @Raul.Galdran , when the parameter type is not right for the query method, I thought it would return an exception but it just returns “None”…
So here’s an alternative to make sure all parameter types are handeled :

import clr

# Import RevitAPI
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *

# Import DocumentManager and TransactionManager
clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager


doc = DocumentManager.Instance.CurrentDBDocument

s = doc.FamilyManager.CurrentType

pl = doc.FamilyManager.Parameters

Name_Parameter = IN[0]

p = [i for i in pl if i.Definition.Name == Name_Parameter][0]
UIunits = p.DisplayUnitType
vals = s.AsString(p), UnitUtils.ConvertFromInternalUnits(s.AsDouble(p),UIunits), s.AsInteger(p)
v = [v for v in vals if v != None]

OUT = v

I also added some code to get the current UI units in your family document and do the convetion automatically. That way all units will be handeled automatically.

@Mostafa_El_Ayoubi

I tried your last code and still doesn’t read text neither integer. I’ve modified " in a really crappy way" but now works with every Parameter Type i’ve tried. ( Text, integer, number, area, length, and several units more), all returned the value from the parameter.

The problem was (UIunits = p.DisplayUnitType) in text/integer…!

I copy the final code:

import clr

# Import RevitAPI
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *

# Import DocumentManager and TransactionManager
clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager


doc = DocumentManager.Instance.CurrentDBDocument

s = doc.FamilyManager.CurrentType

pl = doc.FamilyManager.Parameters

Name_Parameter = IN[0]

p = [i for i in pl if i.Definition.Name == Name_Parameter][0]


try: 
	UIunits = p.DisplayUnitType
	vals = UnitUtils.ConvertFromInternalUnits(s.AsDouble(p),UIunits), s.AsInteger(p)
	v = [v for v in vals if v != None][0]

	OUT = v
except Exception:
	
	vals = s.AsString(p), s.AsInteger(p)
	v = [v for v in vals if v != None][0]

	OUT = v

Thanks again for your time and solutions
