# Explore a Model Architecture

With a model open (see [Open Your First Model](/docs/get-started/open-your-first-model)), this walks through navigating it - both as a tree and spatially - ending with you comfortably jumping between the two.

## Steps

1.  In the **Outliner**, expand a layer. Notice its modules (attention, MLP, and so on) listed underneath - this is the same [address-space hierarchy](/docs/core-concepts/model-architecture-layer-module) every other view uses.
2.  Click a module in the Outliner. The [Architecture view](/docs/editors/architecture-editor) camera frames it automatically (equivalent to pressing `F`), and it's highlighted in 3D.
3.  In the Architecture view itself, try the reverse: click a module directly in 3D space. The Outliner's selection updates to match - selection is shared, not separately tracked per view.
4.  Press `Home` to frame the whole model again, then `/` to isolate your last selection and hide everything else temporarily.
5.  Open the **Overlays** popover and toggle on shape labels - every tensor now shows its shape directly in the 3D view, without needing to click into anything.

If clicking a module in the Outliner highlights it in 3D, and clicking in 3D updates the Outliner, you've confirmed the two are synchronized - this is the core navigation pattern every other Tensormorph workflow builds on.

## Why this matters going forward

Every workflow from here on - inspecting a tensor, comparing two models, tracing a runtime pass - starts with finding the right place in this same address space. The tree gives you names and structure; the spatial view gives you scale and relative position; switching between them costs nothing, since they're two views of the same selection.

## Next step

Continue to [Inspect a Tensor](/docs/get-started/inspect-a-tensor) to look inside a specific tensor you've navigated to.
