Change Structural Plan Type

Hi :slight_smile: ,

Does anyone here on the Dynamo Forum know which API call should be used to switch between different Structural Plan types?

I’ve been looking for a solution to this but can’t find anything.

Best regards,

Hello @mikael.zeylonGRFY6 and welcome…you could try something viewfamilytypes is from rhytm

Hi @sovitek!

Thanks for your answer :slight_smile:

That’s a good idea.

What I had thought was how to change this via the Revit api. I end up having to write this code in C# so I’m just trying to solve it via Python and the Revit Api in Dynamo at a first stage.

Do you have any ideas on how this could be solved with Python?

Hello @mikael.zeylonGRFY6 …if you mean for viewfamily type, then i would take a look on genius loci great node "all elements of type+ its written in python…so you can see how it can be done…good luck

Hello @sovitek and thanks again for the reply.

I don’t think that node can do what I want in this case (or I misunderstood as usual hehe).

What I want to accomplish is to change from ‘Structural Plan - Down’ (default) to 'Structural Plan - Up) via the app.

Thanks again :slight_smile:

an example

import clr
import sys
import System
from Autodesk.DesignScript.Geometry import *
import Autodesk.DesignScript.Geometry as DS

#import Revit API
import Autodesk
from Autodesk.Revit.DB import *
import Autodesk.Revit.DB as DB

#import transactionManager and DocumentManager (RevitServices is specific to Dynamo)
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
doc = DocumentManager.Instance.CurrentDBDocument

#Preparing input from dynamo to revit DB.
view = UnwrapElement(IN[0])
familyViewName = IN[1]

rule = ParameterFilterRuleFactory.CreateEqualsRule(ElementId(BuiltInParameter.ALL_MODEL_TYPE_NAME), familyViewName, True)
filter = ElementParameterFilter(rule)
famViewTypeId = FilteredElementCollector(doc).OfClass(DB.ViewFamilyType).WherePasses(filter).FirstElementId()

#Do some action in a Transaction
if famViewTypeId is not None:


OUT = famViewTypeId

Hi @c.poupin!

Thank you very much, it works exactly as I imagined.

It works in Revit 2020 but not in Revit 2023.
Any idea if it’s a problem with the Revit 2023 api?

Error message:
<TypeError: No method matches given arguments for ChangeTypeId: (<class ‘Autodesk.Revit.DB.Viewplan’>, <class ‘Autodesk.Revit.DB.ElementId’>) [’ File “”, line 48, in \n’].

Best Regards,

It’s an overload issue with CPython/Python.Net use IronPython engine instead (especially since you are going to switch to C# afterwards)


Awesome :slight_smile:

It works! Thank you so much for your help!

Best Regards,
