A "walkthrough" typically refers to a step-by-step guide or demonstration, often from a first-person perspective, such as in video games, real estate tours, or tutorials.

However, if you're referring to an "aerial view" walkthrough, it could mean a top-down perspective of a location, such as a drone-shot video tour of a property or a 3D virtual walkthrough from an overhead angle.

Are you referring to a specific type of walkthrough, like a real estate virtual tour, game level design, or something else?
