Looking for a Guide for Revit Libraries in Pythonshell

babysatch — Mon, 26 Dec 2016 19:26:34 GMT

Hi,

I have noticed often, that people add a reference in their python code in Dynamo to RevitServices by the following code in order to use DocumentManager and TransactionManager:

'# Import DocumentManager and TransactionManager
clr.AddReference(“RevitServices”)
import RevitServices
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.

Thank you.

I would suggest you discuss this with the creators of RevitPythonShell, either in its GitHub source repository, or on StackOverflow, as explained there:

Happy New Year to you!

Cheers,

Jeremy

babysatch,

the problem you are addressing is not a problem of a lack of documentation of the revit api nor is it an issue resulting of the use of the revit python shell as jeremy suggests.

the dynamo addin (application) implements a own document manager and a own task manager. why this is done? consult the dynamo branch on github.

if you now have a python code that accesses a document (what you most certainly will do) or make changes to the revit database you have different options depending if you are in a dynamo environment or not..

i.e python shell.:

import clr
clr.AddReference('RevitAPI') 
clr.AddReference('RevitAPIUI')	

#.......

uidoc = __revit__.ActiveUIDocument
doc = __revit__.ActiveUIDocument.Document

#.......any code to get an elementid

wall = doc.GetElement(element.id)
t= Transaction(doc,"set wall parameter")
t.Start()
wall.LookupParameter("Any shared Parameter").Set(value)
t.Commit()

dynamo python code:

clr.AddReference(“RevitServices”)
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
doc = DocumentManager.Instance.CurrentDBDocument
#......

wall = doc.GetElement(element.Id)
TransactionManager.Instance.EnsureInTransaction(doc)
wall.LookupParameter("Any shared Parameter).Set(value)

TransactionManager.Instance.TransactionTaskDone()
OUT = wall
