Intergraph Smart 3D

Starts 3D navigation in the active window. Smart 3D provides several ways to navigate through your 3D model data so that you can pick a scheme that is most comfortable or familiar to you. There is a fly mode navigation that provides a fluid, multi-directional motion for moving and looking around the model.

  • When you enter 3D navigation, the current model view (defined in the Format View settings) automatically changes to a Perspective projection mode with a Smooth Shaded render mode. The current aspect setting does not change. For 3D navigation, a perspective view shows the three dimensions of an object and provides a more real-life representation of objects because it conveys depth. The further the object surface is from the eye, the smaller it appears in the view. When you exit 3D navigation, the view switches back to the original Format View settings.

  • The camera focal point is determined by the view depth of the object closest to the screen center point when entering or exiting 3D navigation. The focal point of 3D navigation is the center point of the display window. When you enter and exit 3D navigation and the view transitions to and from perspective projection mode, the center focal point stays in the same location. However, objects that were not at the center of the window could display closer or further away. To make the projection mode transitions appear smoother, you can modify the view so the object of interest is at or near the center focal point when entering and/or exiting 3D navigation.

  • When you use 3D navigation, the Next View and Previous View commands do not record the view changes. The Next View and Previous View commands only remember the state of the view before and after the 3D navigation changes.

  • You can enable 3D navigation in each window you have open. After you click Navigate View, the 3D Navigator displays in the active window. When you click on another window with 3D navigation still enabled, the 3D Navigator moves from the previous window to the currently-selected window.

The Navigate View command always sets the current tilt angle to 0 when it is enabled. The system does not restore the previous tilt angle when 3D navigation is turned off. To get back to the rotated view you were using before entering 3D navigation, select View > Previous View.
