About Dynamic Viewing
Creo Parametric dynamically displays the model as you reorient your view. For example, as you spin, pan, zoom or turn an item, you see it change as you move the mouse.

Spin, Pan, Zoom and Turn are all achieved by clicking the middle mouse button, and except for Spin, in combination with either the SHIFT or CTRL key.
