How Do I Draw Navigation Lines in CC3?

[OUdaveguy98]

Hi everyone. New to the community and trying to quickly get up to speed on CC3. I'm wondering if anyone knows how to quickly create nav lines on CC3 and how do I get them to appear over top the sea, but run underneath my land masses. Thanks in advance!

I don't know the best way to draw nav lines but to get them over the sea but under land masses is easy. But the nav lines on one sheet, and the land masses on another and the sea on a different one. then order the sheets so (from top of the list down) you have land masses, nav lines, sea

Thanks! I must have put all my land masses on the Sea sheet.

There are two main kinds of systematic line on a map, rhumb lines and graticules. Rhumb lines are lines of constant bearing, which means if you follow a bearing on a compass, you will trace out a rhumb line. If the map is large scale(zoomed in) or if it's in the Mercator projection, they will be straight lines. Rhumb lines and Mercator were used for dead reckoning navigation. Systematic ones look sort of like a cat's cradle or a bit like a spider web. They can also look like a set of star bursts distributed over the map.

Graticules show a coordinate system on the map, usually latitude and longitude. Depending on the projection and coordinate system you are using, they will appear as a grid of some sort though the shape varies.
