For an agent to work on your designs, your designs have to live somewhere it can reach, and so do the people reviewing them. A model trapped in a single engineer's CAD seat is not something a manager can look at, a supplier can comment on, or an agent can act on. The work scatters into exported screenshots and email threads, and the design itself, the one real source, stays locked on one machine.
The bananaz viewer is where that changes. Your parts and assemblies open in the browser, live and in 3D, for anyone who needs them, and it is the surface where review, discussion, markup, and the Design Agent's own work all happen against the same model. It is not a picture of your design. It is your design, in one place, where the whole loop runs.
A Real 3D Viewer in the Browser
The viewer renders your actual parts and assemblies in the browser, with the controls an engineer expects. You get clean rendering, standard views to orient quickly, and an assembly tree to move through a product structure. You can show and hide parts, isolate what you care about, and make components see-through to get at the detail underneath, all without a CAD license and without leaving the page.
That matters because review is a team sport played by people who mostly do not hold CAD seats. Managers, quality, manufacturing, sourcing, and suppliers all need to see the design, and until now that meant someone exporting views for them. When the live model opens in a browser tab, the people who need to weigh in are looking at the real thing instead of a flattened copy of it.
Mark Up the Live Model, and the Agent Can Act on It
The headline capability the viewer unlocks is marking up the model directly. On any part or assembly, you click the pencil and draw on the model with pen, shapes, arrows, and text, right where the issue is. Each markup is saved as a snapshot of that exact view, the camera angle and whatever you hid, isolated, or made see-through to frame it, and those snapshots live in the Comments drawer. Open one and the camera flies back to the saved view with your markup over the live model, so the person reading it sees exactly what you saw. Teammates comment on a snapshot the same way they do on a 2D drawing markup, and a link opens it directly.
What makes this more than annotation is that the Design Agent can read those markups and carry out the change they describe. You circle a feature, write what needs to happen, and the fix comes back as validated work to approve. The viewer is what makes that loop possible, because the markup and the model live in the same place the agent works. We went deep on this in our post on 3D markups.
One Place, One Source of Truth
Because all of this happens on the same live model, nothing drifts out of sync. The view a reviewer marked up, the comment a supplier left, the change the agent made, and the revision that gets approved are all tied to the same design, and that design stays the single source of truth in your PDM. There is no exported copy aging in someone's inbox, no screenshot that no longer matches the part, no second version of the truth to reconcile.
That is the real shift. The viewer turns the design from a file one person opens into a place the whole team, and the agent, works together, with the model itself as the thing everyone is looking at and acting on.
Why It Matters
Most of the friction in engineering collaboration comes from the design being hard to reach. The people who need to see it cannot open it, so it gets copied, and every copy is a chance for the conversation to drift away from the real part. Put the live model in the browser, let people mark it up in context, and let the agent act on those markups, and the design stops being a file that gets passed around and becomes the shared surface the work happens on.
That is what it means to put the model at the center.
