Local Cartesian System and Earth`s curvature

Hello,

It turns out that Jag3d "knows" that the angle between the plumb lines at points A and B at a distance between them, say, 1000m, is about 33 ". And it uses it in the calculations.

Yes. The tilt can be derived by some geometric calculations. Just try it out and chose the option "local Cartesian system" to see the difference.

Kind regards
Micha
