Hi.
I’d like to delete all the view templates not in use before sending the 100% Final Design file to the client.
Looking into the forum https://forum.dynamobim.com/t/use-dynamo-to-delete-all-view-templates/4434 I managed to delete all view templates, but first I’d need to remove from the list the ones in use.
This workflow will delete all view templates but the 3d ones:
The idea is to delete the ones not in use.
Hi @franciscusm ,
This should work :
import clr
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import*
clr.AddReference('RevitServices')
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
doc = DocumentManager.Instance.CurrentDBDocument
views = FilteredElementCollector(doc).OfClass(View)
appliedtemplates = [v.ViewTemplateId for v in views]
templates = [v.Id for v in views if v.IsTemplate == True]
toDelete = []
for t in templates:
if t not in appliedtemplates:
toDelete.append(t)
TransactionManager.Instance.EnsureInTransaction(doc)
for e in toDelete:
doc.Delete(e)
TransactionManager.Instance.TransactionTaskDone()
OUT = '%d Template(s) deleted' %(len(toDelete))Thanks both for your replies!
Task done, removed 354 unused view templates. I’ve tried both methods, but as we are using Revit 2014 here I’m stuck to Dynamo 0.8, so the second one was lacking updated nodes. Mostafa’s Python script worked fine with 2014.
I kept both for my records. Thanks.
I realize this is an old topic. I am doing some View Template work and ran across this thread. I have grabbed all the views in the OTB Architectural Imperial template and queried them to see if they are view templates and two items (2 and 20) show up as Null. If you select by ID in Revit, they show up as strange items on Properties: ???
Here’s an image:
Any idea what these two weird views are? Can they be deleted? Thanks
I was able to filter no problem. I was just wondering about deleting these views from Revit. Thanks.
If there are two of them, I think they pertain to ProjectBrowser and SystemBrowser views. There is even a ViewType for them:

I don’t think you can delete them. I don’t think you can do anything with them, but that’s because I never tried.
Well that makes sense. I think that I agree, deleting those would be a bad idea… Thanks.
Hi Mostafa,
Sorry to drag up this old topic but I was wondering if you could help with adding an ‘if’ true/false toggle to the code so that it needs a true value to execute the code.
I’m trying to make the purging of view templates compatible with DataShapes so I can issue a warning message to the user before running.
how can the 3d view template types be deleted with dynamo? I can delete with dynamo the view templates of floor plan, rcp, elevation types only but the others remain
Hi @ruben.romero I think that the python script of @Mostafa_El_Ayoubi works as expected, it deletes also the 3d view template not applied by Id. Cheers
Has to be done in Python. Dynamo cannot pass 3d view templates on the canvas (always ends up being null).
This seems to be working in R22 cpy3- 100% python.
