This is a feature request really. I'd like to see some basic plotting functions incorporated into MacENC. The bearing and distance tool is already there but I'd like to see that expanded so that you could draw a, temporary, route in with multiple legs but without using waypoints.
Perhaps as an example I can explain how I use this feature for weather routing in another application.
1. I Display a grib file for current location and route
2. I step through the grib in six hourly increments for the first 24 hours drawing in my expected course and distance for that time period (the other app has a course and distance measuring tool similar to the MacENC one but once the mouse is released the line stays on display until the tool is turned off).
3. I draw in predicted course and distance for the next couple of days at 12 or 24 hourly intervals.
4. Look at a few different options to see which one gives the best result.
I don't want to use or create waypoints as I am usually sailing or motor sailing based on wind/sea state therefore this is just a best guess as to what I'll achieve over the next hours and days. It's quick and dirty weather routing but it works.
