I'm having trouble drawing a path depicting a vessel's movements. For example, from some starting point, go 123 miles on course 091°, thence 73 miles on course 346°, etc.
Drawing any single leg of the trip is no problem. I can make a straight line of a given length, then rotate it to the correct orientation. However, creating these legs individually and placing them end to end gives the diagram a klugey look. The corners don't have the perfect appearance of a path created by successive clicks with the pen tool.
I can get the diagram just right by first roughing out the path by eye, then using the Inkscape XML edit feature to modify the node coordinates. To get the correct numbers I perform vector math on a calculator. This is laborious and blunder-prone. Is there a better way?
