To change the view mode

Select an option on the View tab > Mode panel > View Mode menu to switch between milling and turning view modes. These modes determine how the model is orientated in the graphics window.

Milling — When active the Z axis is vertical in the graphics window. For example, the Top view displays the XY plane.

Turning — When active the Z axis is horizontal in the graphics window. For example, the Top view displays the ZY plane.
