Is the scene view in Unity used for building scenes?

The scene view in Unity is indeed used for building scenes, which is why this answer is correct. The scene view provides a 3D representation of the environment where developers can manipulate the placement of game objects, adjust their properties, and design the layout of levels or scenes visually. This allows you to see how components will interact with one another in the actual game environment and enables you to iterate quickly as you build and refine your game.

In contrast, while the scene view is primarily for scene creation and level design, other options do not accurately reflect its capabilities. For example, it's not limited to just testing or modeling; the scene view encompasses both of these activities but is fundamentally focused on the overall construction and design of your game level or environment.
