This is a question for those who use trigonometry in Blender modeling. I want to place a long, thin object (like a plank or a girder) so that the ends are at two specific xyz points. Calculating the length (distance between points) is easy—sqrt(xx+yy+z*z). However, there are several different ways of calculating the angles in space. Which method is correct for Blender? I want to be able, to just punch the numbers into the “transform properties”, rather than trying to “feel” the piece into position, with the rotate command. Also, I would like to avoid using control-A.
Any other math whizzes out there?
