Projection Preferences

The Projection preference in the 3D Viewer Preferences dialog offers the following options for projecting a 3D model on a scene:

Orthographic: to show all objects on a 3D scene at the same scale regardless of their distance to a user. The farthest and nearest objects have the same size. This setting is default and reflects the legacy orthographic view projection behavior.

Perspective to show the following:

• To show all objects on a 3D scene at different scales correspondingly to their distance to a user. The farther objects have smaller sizes than the nearer ones.



• To zoom through a model. A user can view the model from the inside.
