Learn To Navigate

Navigation is very simple and requires only a little bit of practice. Scenome uses only one "mode" for navigation but uses all three mouse buttons. Navigation is slightly different in perspective and isometric views but the buttons perform very similar functions.

Navigation speed is affected by the Far Clipping Plane value. A larger value increases the amount of motion because it is assumed that the database is very large. You can change the navigation speed at any time by selecting Worksheet » Properties and changing the Far Clipping Plane value in the Camera Settings property group.

You must have a three button mouse to navigate.
