See your model with perspective or orthographic 3D views.
Perspective 3D Views
Perspective 3D views show the building model in a 3D view where components that are further away appear smaller, and components that are closer appear larger.
You can select elements in a perspective view and modify their type and instance properties. When you create or view a perspective 3D view, the View Control Bar indicates that the view is a perspective view.
Example
Orthographic 3D Views
Orthographic 3D views show the building model in a 3D view where all components are the same size regardless of the camera’s distance.
