I have tried to create assembly views by selection of reference assembly & target assembly but python script is not working. I tried create by below reference but failed .Please help me to create views.

What is the script returning? Was this code possibly written by AI? The AcquireAssemblyViews method is part of the AssemblyViewUtils class, not AssemblyInstance. This method also does not create new views, just move existing views to a new owner.

“Transfers the assembly views owned by a source assembly instance to a target sibling assembly instance of the same assembly type.”

@Nick_Boyts you are right I have created this python script using ChatGPT .Thank you for clarifying concept. But currently I want to create assembly views using string as like Evolvelab node AssemblyInstance.CreateViews , but it is not working . I have pasted script below can anyone modify it to create views using string.
import clr
import sys

clr.AddReference(“RevitNodes”)
import Revit
clr.ImportExtensions(Revit.GeometryConversion)

#Import Dynamo Revit Libraries ‘RevitServices’ Namespace#
clr.AddReference(‘RevitServices’)
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

clr.AddReference(“RevitAPI”)
import Autodesk
from Autodesk.Revit.DB import *

from System.Collections.Generic import *

doc = DocumentManager.Instance.CurrentDBDocument
app = DocumentManager.Instance.CurrentUIApplication.Application

data = IN

view_orientations = [
AssemblyDetailViewOrientation.ElevationBack,
AssemblyDetailViewOrientation.ElevationBottom,
AssemblyDetailViewOrientation.ElevationFront,
AssemblyDetailViewOrientation.ElevationLeft,
AssemblyDetailViewOrientation.ElevationRight,
AssemblyDetailViewOrientation.ElevationTop,
AssemblyDetailViewOrientation.DetailSectionA,
AssemblyDetailViewOrientation.DetailSectionB
]

view_orientation_names = map(lambda x: x.ToString(), view_orientations)
assembly = UnwrapElement(IN[0])
view_types_to_create = IN[1]

views =
TransactionManager.Instance.EnsureInTransaction(doc)
for view_type in view_types_to_create:
view_orientation = None
try:
if view_type != ‘3D View’:
view_orientation = view_orientations[view_orientation_names.index(view_type)]
else:
pass
except:
continue
if view_type == ‘3D View’:
view_created = AssemblyViewUtils.Create3DOrthographic(doc, assembly.Id)
view_created.Name = ’ - '.join([assembly.AssemblyTypeName, view_type])
else:
view_created = AssemblyViewUtils.CreateDetailSection(doc, assembly.Id, view_orientation)
view_created.Name = ’ - '.join([assembly.AssemblyTypeName, view_type])
views.append(view_created)
TransactionManager.Instance.TransactionTaskDone()

Assign your output to the OUT variable.

OUT = views

  • What’s the issue you’re having with AssemblyInstance.CreateViews? If that’s the method you want to use, it would probably be best to troubleshoot it rather than create a whole new python script.
  • Always paste code using the preformatted text option (</> in the formatting toolbar) so that your code retains its formatting. We can’t really help if your code has lost all formatting.
  • This forum is not a place to request that others do your work for you. You need to show effort as we work through the issue with you.

@Nick_Boyts I have created python script using AI & it works for me creating All assembly views .It had worked for me. is there any way to create views using filter of view name? Actually I have just basic understanding about Revit API & Python. It would be helpful if you help.

So you have code that works by passing the view element instead of the view name and you want it to take the view name? It’s always best to post the python code rather than sharing the file so we don’t have to reproduce your exact case. If you want to use the view name then you just need to pass that through and then check each view one by one to compare names. If the names match, continue to the view creation.

You can do the comparison ahead of the python code with some pretty basic nodes, or you can use a FilteredElementCollector to get all views in the project.
