Creating a new world

For the sake of simplicity, when creating a new Build the Earth world, use the World Type: Build the Earth in the More World Options... screen as shown below.

But if you want to manually configure the world options, using the world type Planet Earth, first use the value 7318261.522857145 for the scale values (as shown in step 1), then switch the projection to BuildTheEarth Conformal Dymaxion (as shown in step 2), then add a new transform (step 3), and change the newly added transform to Vertical Flip (step 4).
