This is very good, a query added the nodes that were missing from Civil 3D Toolkit Dynamo 2025 packages are still compatible with the 2026?

@DJack sorry, I’m not sure I understand your question. Can you break it down for me? :slight_smile:

Sorry, I think I did not explain myself well.
I was asking if Civil3DToolkit had nodes that were no longer in civil 2025, my question is if these nodes have been added in 2026 for example the node to add radius in a profile no longer worked in 2025 PVIandRadius.

I was also asking if the packages that are now supported in 2025 will still work in 2026.

Sorry, but I don’t have any information about the Civil 3D Toolkit package. You can read about all of the new features (including new nodes) in the blog post above :backhand_index_pointing_up: and the official release notes.

We don’t exhaustively test all third-party packages as we don’t own/maintain them, so I can’t guarantee anything. But I wouldn’t expect any compatibility issues. The Package Manager now shows compatibility information when you download a package, so assuming that the author of the package has updated this information, then you can rely on it :slight_smile:

I have had quite a lot work with viewports recently and one thing I was looking for but didn’t find was “Viewport” in node “Choose Object Type”. Maybe it can be added into that dropdown node, then the node “All Objects of Type” could be used straightforward.

@markus.toon it is the same as using the Layout.Viewports node, right? Actually a lot fewer nodes that way :slight_smile:

@zachri.jensen I am using Layout.Viewports node in my graph, but it has that little “trick” that it returns activated viewports only. So I have to keep in mind to set CTAB variable on all layouts to make sure all viewports are “visible”. But to shorten the flow I was thinking if all viewport objects are selected with nodes "Choose Object Type” and “All Objects of Type” maybe all viewports would reachable with these two nodes.

@zachri.jensen
I am using Civil 3D version 2026. How do I update Dynamo?
I am looking for some features and cannot find them.
Thank you.

@jc.alves When using Dynamo inside of some other application like Civil 3D or Revit, it is all bundled together. So you don’t update Dynamo separately. Dynamo updates come when there is an update to Civil 3D. The latest version is Civil 3D 2026.1, which comes with Dynamo 3.5.2.
