FT3 Equator

Umbratikus

What are the grid settings in FT3 to create an Equator only?

This quite possibly isn't the right way to do it, since you can't add a secondary grid this way, but I've often marked the equator by making the polar caps extend to 89 degrees.

The latitude polar endcaps are a quick way to limit all grids without having to edit each one separately. However, it does get in the way of wanting to do things like having multiple grids with different limits.

To get a single equatorial line while still allowing other grids, set Latitude Polar Endcaps to zero (0), add a grid, and set the top and bottom regions of that grid to zero (0) as well.
