Like many other CAD solutions, the product structure in Asset Transformer Studio designates the scene tree (or scene hierarchy), which provides a structured view of the occurrences of the scene.

When a CAD/3D model is imported in Asset Transformer Studio, the Product Structure reflects its hierarchy as it was designed in the CAD/3D solution that produced it.

Then, this hierarchy can be modified to fit the user's need, interactively or through Python scripting.

Finally, when a scene is exported (see Supported File Formats), the Product Structure is kept as displayed in the Product Structure panel (if the format supports the tree concept).
