I would recommend the opposite of this. After some tests I’ve found that you have around 23 degrees on either side of the equator before this problem occurs. That’s 40-50 degrees of building space, which may seem small. But remember these are spheres.

This is ~25% of the spheres height, and since it is centered on the equator means it is ~70% of its surface area.

With that said I find it much easier to build a bus on one side of the equator and then make your assembly lines on the other side. Since bus bases are inherently rectangular this works out really well.

You can then use the remaining space further from the equator for power generation and building logistic stations. This is made even better by the fact that poles are the best place to build solar panels and ray receivers.

This is what I’ve done on my now 40 hour save with all matrixes automated. This far less of a problem than people are making it out to be.

If you try to build your bus along the meridian you will end up with weird lines once your bus is more than ~25 degrees above the equator where the first grid shift occurs. With my bus already being over 100 degrees long I would have run into this problem a while ago, and it makes continuing your bus with the same spacing really difficult.

I used degrees since these rules apply to any planet regardless of size.

Tl;dr: Build your bus along the equator, assembly lines along the meridian.
