If you want to select all of the viewports (drawings is the correct term), activate the Drawing tool and press CTRL+A.
That will select all of the drawings.
You can place a marquee around an area and do the same thing.
That will limit the selection to just the marquee area.
Or you can activate the drawing tool, hold SHIFT and just sweep the mouse to select all drawing in the area you sweep across.
The same applies to all other elements (doors, windows, walls, slabs, etc.) in Archicad
Select the tool for the element you want to select and do one of the above.
