World Machine: selecting different location?

Hey guys, is it possible to select a different location for the same terrain in world machine? I do not want the part of the terrain, so can I move that white box to another location? Sorry, I am a beginner and I don’t know how to be specific. Ask me questions if you need more clarification please.

To the best of my knowledge do this:

  1. Go to the Layout tab (the one to the left of the globe looking icon)
  2. Under “Mode” there are three icons. Click the middle one that looks like the extents box.
  3. To move the whole box click inside the extents and drag. To move the corners individually, click and drag them.
    Hope that help you out.
