If the arc segments of a given ring had an arc crossing the equator at one side of the earth, but had no arc segment on the opposite side at the equator, the centre of the arc group’s bounding box would not correspond to the centre of the ring the arcs are supposed to lie on. The Hollow Earth depends on all the rings having a common centre.

The use of sizing pixels also solves a related issue, to do with horizontal positioning.

This is an earlier version, with 72 rings, and also shows the individual arcs. You can see them in this screen shot from Xara 3D, I’ve exaggerated the bevel and reduced the extrusion to make them easier to see. To prevent this, the sizing pixels are brought into play. In the context of the arc segments for the Hollow Earth, the problem is that depending on which arcs are preserved in a given ring the overall height may differ from ring to ring, so Xara 3D will adjust their relative sizes. Thus Xara 3D makes no attempt to resize them, as they already have the same size. Some years ago, someone (no-one really remembers who, now, but it wasn’t me!) realized that you can preserve such size and position relationships by creating a pair of pixel-sized dots at the top-left and bottom right of the working area in Xara Xtreme for example, and that by adding the two dots to each shape before exporting it to Xara 3D, all such shapes acquire the same overall bounding-box, that of the two dots. You can correct that within Xara 3D, but the tools to do so can be a bit clumsy, and I don’t normally use them. This often has the effect that shapes that had specific size and position relationships to each other before importing, lose that relationship when they appear in Xara 3D. Sizing One of the annoying things that Xara 3D does is resize imported shapes to make them all conform to the same height.
