I have noticed often, that people add a reference in their python code to RevitServices by the following code in order to use DocumentManager and TransactionManager:
'# Import DocumentManager and TransactionManager
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
Does anybody have an idea where I can find all methods, properties and members of the Revit librares “RevitServices” and RevitNodes . I cannot find them in RevitAPI.chm.
