Cut with Void When Loaded Parameter Family Document.

[mr.engineer.aec]

 Hi All,

I'm trying to set value for Cut with Void When Loaded Parameter in Family Document but familyParameter return null;
I checked newFamilyDocument != null.
Whether I did it right or not ? And how to fix it. 
Many thanks !

FamilyParameter familyParameter = newFamilyDocument.FamilyManager.get_Parameter(BuiltInParameter.FAMILY_ALLOW_CUT_WITH_VOIDS); //familyParameter return null when debug.

newFamilyDocument.FamilyManager.Set(familyParameter, 1);

Hi @mr.engineer.aec ,

Try using this below code

Parameter p =doc.OwnerFamily.get_Parameter(BuiltInParameter.FAMILY_ALLOW_CUT_WITH_VOIDS);
p.Set(1);
