# Standard Views

If you rotate a view to a standard orientation, the view orientation displays, along with the view number, in the view's title bar.

## 2D Views

In 2D, the design plane is parallel to the screen and, in effect, you view the model from above. The default (unrotated view) in 2D is like a Top view with its orientation such that:

• The x-axis is positive from left to right (horizontally).
• The y-axis is vertical, and positive from bottom to top (vertically).

In a 2D model, you rotate a view about an imaginary z-axis, which is perpendicular to the screen. No matter how you rotate a view in 2D, effectively, you still view it from above.

## 3D Orthogonal Views

In 3D, since you can rotate views about three axes, rather than just one, there are six orthogonal orientations, each of which corresponds to a standard orthogonal view: Top, Bottom, Left, Right, Front, or Back. The name of the view describes also the position from which the model is viewed.

### The faces of this cube correspond to the 3D orthogonal views. The cube is displayed here in an Isometric view.

A Top view displays the model from the top:

• the xy plane is parallel to your screen (as in a 2D model).
• x is positive from left to right (horizontally).
• y is positive from bottom to top (vertically).
• z is positive toward you, perpendicular to the screen.

While, for a Bottom view:

• y is positive from top to bottom (vertically).
• z is positive away from you, perpendicular to the screen.

A Front view displays the model from the front:

• the xz plane is parallel to your screen.
• x is positive from left to right (horizontally).
• z is positive from bottom to top (vertically).
• y is positive away from you, perpendicular to the screen.

While, for a Back view:

• x is positive from right to left (horizontally).
• y is positive towards you, perpendicular to the screen.

A Right view, displays the model from the right:

• the yz plane is parallel to your screen.
• y is positive from left to right (horizontally).
• z is positive from bottom to top (vertically).
• x is positive toward you, perpendicular to the screen.

While, for a Left view:

• y is positive from right to left (horizontally).
• x is positive away from you, perpendicular to the screen.

## Isometric Views

There are two other standard views — Isometric and Right Isometric. These views are rotated so the three faces of a cube orthogonal to the design cube axes are equally inclined from the screen surface.
