Rotating, Moving and Zooming in the 3D viewer
Much of the interaction in 3D can be performed using the mouse and mouse wheel, or keyboard shortcuts. Use the mouse to rotate the view around as well as zoom in, or use the 3D View tools for rotation, moving and zooming described below.
The Rotate operation allows rotating the scene around the current pivot axis, or tilting the scene on an axis that parallels the view window plane, by moving the mouse with the left button down.
Keyboard shortcuts
- To lock along one dimension or the other, press either of the 'V' or 'H' keys. The 'V' modifier (Vertical only) enables tilting but disables rotating around the pivot axis; the 'H' modifier (Horizontal only) disables tilting but enables rotation.
