To define the front view ■ Right-click the ViewCube tool, and click Set Current View as Front. To restore the Front view ■ Right-click the ViewCube tool, and click Reset Front. Set the View Projection Mode The ViewCube tool supports two different view projections: perspective and orthographic. Orthographic projection is also referred to as parallel projection. Perspective projected views are calculated based on the distance from a theoretical camera and target point. The shorter the distance between the camera and the target point, the more distorted the perspective effect appears; greater distances produce less distorted affects on the model. Orthographic projected views display all the points of a model being projected parallel to the screen. Orthographic projection mode makes it easier to work with a model due to all the edges of the model appearing as the same size, regardless of the distance from the camera. Orthographic projection mode though, is not how you commonly see objects in the real world. Objects in the real world are seen in perspective projection. So when you want to generate a rendering or hidden line view of a model, using perspective projection will give the model a more realistic look. The following illustration shows the same model viewed from the same viewing direction, but with different view projections.

Set the View Projection Mode
The ViewCube tool supports two different view projections: perspective and orthographic. Orthographic projection
is also referred to as parallel projection. Perspective projected views are calculated based on the distance from a
theoretical camera and target point. The shorter the distance between the camera and the target point, the more
distorted the perspective effect appears; greater distances produce less distorted affects on the model. Orthographic
projected views display all the points of a model being projected parallel to the screen.
Orthographic projection mode makes it easier to work with a model due to all the edges of the model appearing
as the same size, regardless of the distance from the camera. Orthographic projection mode though, is not how
you commonly see objects in the real world. Objects in the real world are seen in perspective projection. So when
you want to generate a rendering or hidden line view of a model, using perspective projection will give the model
a more realistic look.
The following illustration shows the same model viewed from the same viewing direction, but with different
view projections.

Home View
The Home view is a special view stored with a model that makes it easy to return to a known or familiar view.
You can define any view of the model as the Home view. The saved Home view can be applied to the current
view by clicking the Home button above the ViewCube tool or from the ViewCube menu.
To define the Home view
Right-click the ViewCube tool, and click Set Current View as Home.
