How to rotate, move & zoom easily in SCIA Engineer?

In the bottom right corner of the work area there are some scroll bars to manipulate the view angle in the model.

It is also possible to do this via some hotkeys:
SHIFT + right mouse button = Move
Clicking on the scroll wheel = Move
CTRL + right mouse button = Rotate
SHIFT + CTRL + right mouse button = Zoom
Scroll wheel = Zoom

Tip: If you want to rotate around a certain element or node, you should select it before performing the rotation. SCIA Engineer will then rotate around the selection.
