This ASM Techbase blog is concentrating on the 3D window. Knowing how to move around in the 3D window will speed up the wholes process of your workflow.

TO GET STARTED I DID OPEN ONE OF MY ARCHICAD TUTORIALS
Here we got the 2D Floor plan view

Next hit F5 on your keyboard and we are in the 3D window view

The mouse default with F5 is on orbit. So if you now left click/hold and you move your mouse cursor you are orbiting around the model. You can change the orbit origin if needed. All you have to do is select something in your model you like to orbit around or you.
To get out of the orbit option hit O like orbit J and the curser changes to the arrow tool.
