Walking

Basics

Hold down the left mouse button to move around in the model. You can move forward or backward by dragging the mouse up or down, respectively, and turn by moving the mouse cursor left or right. The cursor's distance from the center of the 3D view controls the movement speed. While holding down the left mouse button, you can start panning the view by holding down also the right mouse button. And if you then release the left mouse button, you can start turning the camera.

Look up or down

Hold down the Ctrl key and press arrow up or arrow down to rotate the viewing direction up or down.

Restore horizontal view
