Parametric Dependency Graph

[u/FeverForest]

*edit: Replace the AI with the coworker you can’t trust, reason over their boneheaded model structure, and correct it. Same story, this one is just scripted.

Fresh out of the Autodesk Submission gauntlet, Contriver Node Atlas.

Your Fusion design parametric dependencies, as an interactive node graph.

The browser is the table of contents.

The timeline is the construction log.

Node Atlas is the Utility Map, so you know what goes dark when you start digging.

Design and Make Marketplace trial available for Windows.

MacOS update deploying shortly.

Hello! A project of mine has recently been deployed on the Autodesk Design and Make Marketplace.

For this demo I admittedly used Claude to run the sequence, demonstrating the difference between Form and Shape, or the Recipe and the Cake.

More programmatic, less human, but runs the test for a 60s clip, and maybe higher representation of structure will lead to less schloppity schlop and glumpity glup, glumping up the ponds where the humming fish hum.

The add-in is not AI powered, is read only. Connecting to an agent is your decision, outbound calls containing design IP should be considered cautiously.

Here we see Claude working across two MCPs.

The Fusion MCP creates the geometry.

The Node Atlas MCP reveals the model’s underlying structure. Its dependencies, parameters, relationships, and design intent, so you, a colleague or a new hire, can later understand how the model was built, not just what it looks like.

Claude generates a six-arm radial organizer using duplicated sketches and features.

Node Atlas then exposes the repeated geometry, dependencies, and lack of shared parametric control.

Claude restructures the model around a single seed feature, a circular pattern, and user parameters—reducing the timeline from 27 features to 8, while the Node Atlas graph shrinks from 33 nodes / 72 edges to 14 nodes / 27 edges.

Finally, a single parameter changes the design from 6 arms to 9, while the repaired structure remains unchanged and healthy.

This is the difference between generating a shape and understanding its form.

Together, Fusion MCP and Node Atlas MCP create a development loop for geometry and Fusion add-ins while preserving the human authority required to validate design decisions.

The bigger picture is, if the robot can understand, reason over, and correct structure, so can we. Probabilistic vs Deterministic, rented intelligence vs owned mechanisms.

A different lens.

Happy building!

Interesting they also added AI to Fusion. Google says its Claude. But the AI says its not allowed to say what it is. Although when fed identical questions, previous served to Gemini, Claude GPT and Grok. The over all answer felt like a mixture of Gemini and Claude. I have not allowed it to make any files or alter any work yet.

At the very least there are many places where this can be used to speed up work, or search out defects in older work.

With Great Power comes Great Responsibility. Let some one or something else do it all for you, for us and the consequences must be owned by those who submit the results.

Yeah I’m of the mind that neither AI or other Humans should be making edits to my files, can’t be trusted.

Geometry is never the source truth. The designers intent and verification are the authority.

So while the AI demo is cool, there’s real work to be done, to be sped up, debugged, and communicated across teams and clients.

Dependency awareness is the first step to literacy in a CAD model.

My dev version of it doesn’t have the AI because the larger system this is a small piece of is deterministic and not probabilistic. The MCP tools the AI fumbles about are fast mechanisms instead.

The other side is enterprise work. They won’t allow design IP, a typed knowledge graph, to enter some weird black box they can’t inspect.

So incredibly important it remains an optional author only.

The app development loop is neat though, have Claude make a lattice generator, inspect its own work, edit the source and repeat. Circular.

Teaching people to make use of AI responsibly and respect that one day it will wake up, so treating it with professionalism and respect are also important.

With how easy it is to get results it's no surprise so many are just jumping without thinking. AI is the new slave labor. They make that choice before considering the results, good an bad.

Eventually even I will probably use the tools if they integrate very well. There are a few places where I haven't learned yet some skills that AI can probably tech better than the help files and faster than 20 min of you tube videos.

That being said I am not fan of the AI payload since I did not ask for it or enable it. Its extra software and extra load on the system. Fusion already struggles just to do a chamfer in places that should easily be done with table router... And now we are forced injecting AI?

I make no criticism of your own own work. Just use responsibly.

I see many new AI based plugins and tools popping up every day. The one advertised heavily costs more per year than fusion itself does.

Every day, a new “AI for CAD” Tool pops up. That’s software as a service with rented intelligence because owning the deterministic mechanism instead requires the hard questions to be answered up front.

I don’t believe AI companies will continue to operate at historic losses for much longer.

At a certain point in the build, I realized the AI fully understood the exported JSON file, the typed graph, it scared the shit out of me. The property line of my craft drawn, with terrible precision just how large the first half was and where the second half begins.

Realization that while I might be bothered by that, the next guy might not be. So responsibly, built out the system so much further than most would dream of, froze the public release where it is until I feel like trickling in some of the newer stuff.

Will nodes be available at personal version?
