You're welcome.

*One last thing. I seem to remember that there's some small differences when using the Imperial system compared to metric. But overall, when plotting for intercept, if the target is going say 7knots, you would plot a circle that is 7nm in diameter, correct? And then I know there's the speed plotting issue, but I think I'll figure that out in a bit here.

Thanks again sirs!

In this drawing it doesn't matter if the linetool uses kilometers or nautical miles. The radius ...radiusses... radi-eye (oh, whatever!) of both circles should be made in the same units. Units of 1km, 1nm, 10km, 10nm, 78km, 78nm, 250 pixels... whatever doesn't matter, aslong as the same is used on both circles of that drawing. The angles in the triangle do not change if the triangle has longer sides but keeps the same shape.

The difference in metric vs imperial units come when plotting positions for determining speeds. Then you need 3 minute periods for imperial, and 3 min 15sec periods for metric. Then every 100 yards, or 100 meters, distance moved by the target amounts to 1 knot.

As for different intercepting methods, I develloped my own drawing technique. Mine allows me to figure out the course to go to manouvre around/towards/away from the target, while keeping up with his own movement. Like extending distance as quickly as possible, draw left or right around him, or like the other picture reduce range asap (pure intercept). If you update this drawing as the target bearing changes then you can move in a nice circle around the target, maintaining your distance. I made this public in an obscure post in the SH3 section. But I never made a good tutorial for it, too lazy.

Take a look at MOBO program in the Mobo forum. It is --how do I say this--unbelieveable.
