In essence, you declare your model in progress a component, and then place three iterations of your component around the original, each rotated the appropriate amount around the relevant axis it ends up looking like this as you work: SketchUp's interface simply doesn't support multiple 3D viewpanes in one interface window the way many other 3D DCC tools do (C4D, modo, Maya, 3DS for example) though there is a workaround, assuming a fairly simple model: see this thread in SketchUp Community on this topic ( link) to see what I mean.
