Would be helpful to see what you have in the graph so we aren’t shooting in the dark. A lot of times creating viewports and placing the in the same graph requires Transaction.End and Transaction.Start nodes. Are you using these?
Putting the level of the last node to place the views was the issue like @bvs1982 predicted.
Changing all inputs to lvl 3 resolved my issue:
This script appears to be exactly what I’m trying to accomplish for mass timber drawings. I downloaded your dyn. but there are various custom nodes that do not appear to be in packages. Is there any chance you would be able to share these? or an updated version of the script?
Can you share a screenshot with the nodes you’re missing?
If they are Python nodes my experience is that the can be replaced with nodes.
I have a script that does the same but without any Python (i believe).
By the looks of it you are missing Packages.
Why not just download the missing Packages?
I have no information on the packages. The Package manager is not indicating a missing package and when I look at the help for these nodes no package is listed there either. That’s why I was hoping Jan could give some insight.
You might be looking at the wrong place.
It should tell you what Packages your missing
somewhere AFAIK.
Look for Extensions at the top bar.
You’re not going to find these packages even if you had the package manager.
The post you are replying to is from July of 2018. That’s 91 months later, and over that time you’ve gone though somewhere between 4 and 7 Revit versions; 19 to 27 Dynamo updates; and (for most supported users today) a .NET update (soon as many as 2). All of this happened after Lunchbox support was ended (a few months before or after this post) so the package author could focus on other projects.
As such you’ll need to build stuff anew. Fortunately there are a LOT of great new nodes for this now. Best to run though the Dynamo Primer if you haven’t already (skip nothing until you get to the end of the Revit section, even if it seems irrelevant, as the primer is designed to teach concepts not give you outcomes) and then try building your own version of the graph you need. If you get stuck after that, start a new topic and include a small Revit model and your Dynamo graph (use a 3rd party site like [OneDrive, Dropbox, Google Drive, WeTransfer, etc.] if you can’t post files) so others can help with the context of the problem you’re facing.
Sharp eye. Missed that 
.
Rhythm still exists and has Viewport.Create though. 
Maybe start a new topic @JCupps with what you have tried and the awesome folks here can get you sorted.
Not my topic @john_pierson .
Thank you for your responses. I was going with the work smarter not harder theory and since Jan had provided a dyn that appeared to do what I wanted was trying to use it. I’ll work through writing one on my own and start a new topic if needed.
To add.
In my opinion using other peoples .dyn isn’t always the smartest.
Especially more advanced .dyns. They are often tailored to their needs and
it will cost you more time to make them work for you instead of
making a .dyn from scratch.
