That was my original query. I do not think, for lines, LC does such a thing at all.All I can say for sure, based on my test before posting, is that the IDE provides a means of adjusting the angle of both line and polygon objects by arbitrary degrees
See posts 2 and 3 from the top above. Both Stam and EdocEvil point out the inherent silliness of my original question, at least the way I phrased it. I expanded (backpedaled?) on that right away, and played around until I got a method to do what I actually wanted, not what I actually asked.
In other words, you cannot set the angle of a line directly; there is no property with which to do so. But you can draw a new one (or change an existing one) to your exact specifications.
