Any good way to find out what packages are associated with a Dynamo graph? I’d like to let others use what I composed, but with only the minimum of referenced packages.

This has been a major request for a long time with little progress so far:

There was a great discussion on some ways to address this here:

For the moment, the graph should list the paths of custom nodes, where the names of the packages can be found, but I have still no idea how to identify which packages the Zero Touch nodes belong to. Any idea, link or contribution are welcome…
using springsUI and some set logic, you could do the following for the active graph:

Of course, an ultimate feature would be to have a graph compile into an Add-In wrapped up similar to Dynamo Player. (Would that it could be hosted in the Autodesk Store, too.)

Issue I see with automated package downloads is that different versions of packages have different node names and functions - by opening a dyn which triggered a download of an older package you would create an issue with two versions of the package on the same system, which can break things.
My recommended work around is to document all custom nodes in the graph, by adding a note indicating which package and version each custom node is from. This way those who are managing package and graph libraries get to make a decision as needed to add content into the system.

Would be even better if the computer did this for us by keeping those data in each node for us to see.

The system isn’t designed to store the data that way - they have to be able to pull from the version of the package which is available - be it an older or newer version of the node/package.

@truevis, @jacob.small, @Konrad_K_Sobon
Put a reference in the namespace, solving another problem at the same time, if possible

> With the latest archi-lab package installed the native “FamilyInstance.ByPoint” will not function in a codeblock and if you try to turn the native “FamilyInstance.ByPoint” into a codeblock via the “NodeToCode” option Dynamo will crash. I suspect the package recycles some reference names that shouldn’t be duplicated. Pulling the package fixes the problem.

This thread might be of interest as it discuss and automate the capture of dynamo nodes, and packages used in a .dyn file.

This got a tad intense, so I have adjusted the Audit node to tell users when a node’s package isn’t found and suggests using the Rhythm node separately. @Steven I am glad that it fu…

Yours is more succinct. Here is my version:
Then paste into a Note eg: “This DYN uses packages: {archilab,Clockwork}”
I published it:

I recently made minor adjustments to @Dimitar_Venkov python with #comments and going step by step to help explain what the code is doing. this is great thank you 🙂
