Panning, zooming and rotating is collectively known under the term navigation. Fairway provides several interfaces for navigation, all of which are designed to not interfere with actions for selection and manipulation. That is, no operation must be interrupted or cancelled for navigation. When used in isolation, the following always applies:
If you don't have a mouse with a middle button you can use the Navigation mode. If the middle mouse button does not work then try to troubleshoot it.
Pan | Zoom | Rotate | |
---|---|---|---|
<MMB> | <Ctrl + MMB> | Wheel | <Shift + MMB> |
<MMB + RMB> | <MMB + LMB> | ||

The table above lists ways to control general pan, zoom and rotate functionalities. Various special navigation instructions are given below, such as zoom all, reorient on curve, spin, fly through and others.
The current view direction is always displayed in the title bar of the view as two angles: one is the view direction relative to the center plane and the other relative to the base plane. If the view direction happens to be perpendicular to one of the main planes, then this is also indicated in words.
The orientation of the model relative to the viewer is indicated by the set of orientation axes displayed in the lower right corner of the view window. The positive length, breadth and height directions are each represented by an indicidually coloured arrow. The orientation axes can be switched on and off and colours can be customized in [File]→[Preferences...]→[General]→[Orientation axes].
For changing the orientation please consult Rotating.
Panning brings different parts of the model into view. Panning is possible in these ways:
Zooming happens in the direction underneith the mouse cursor. Zooming is possible in these ways:
Rotating the camera around the model is possible in these ways:
The center of rotation is set to the center of the visible part of the bounding box of the model. When dragging the mouse from left to right the camera rotates around a vertical axis. When dragging away or towards you the camera tilts around its horizontal axis, whilst keeping the center of rotation in view.
If, while rotating, the <MMB> is released in the middle of a dragging motion, then the camera will continue to orbit around the rotation center, until the <MMB> is pressed again.
The view projection can be toggled between orthographic and perspective using the context menu, or with <Ctrl + Shift + P>. In perspective views, panning rotates the camera around its own center, synonimous with the concept of panning in photography. But zooming is replaced with dollying, meaning that the camera position moves forward or backward. By combining pan and dolly it is thereby possible to “walk” or “fly” through the model in perspective projection. And because dollying happens in the direction under the mouse pointer (as is zooming) it is possible to translate the camera sideways without changing its orientation by dollying in and out in different directions.
Fairway has built-in support for the 6-degree of freedom navigation devices from 3Dconnexion, making it possible to pan, zoom and rotate simultaneously in one smooth motion. The SpaceNavigator devices have two buttons. The left button resets the view to view all of the model, the right button brings up the device configuration panel.
If you have trouble using the navigation device then try to troubleshoot it.
In navigation mode, the left mouse button acts as the middle mouse button, so that it can be used for navigation. Toggle the navigation mode on and off in either of the following ways:
