I am using blender to do the diagrams for an experiment. Maybe its not the most appropriate program, but at least I know how to use it. I am trying to add arrows to my diagram to point in the direction of motion. I am also trying to add an arrow that signals rotation. I want to add them in blender instead of photoshopping them in in order so that they have a 3d orientation if you know what I mean, as in
Of course, I would want my arrows to look professional.
Should I use meshes to model them? Or maybe curves? I was thinking that planar arrows would look better.
Also, is there a way to render some parts of the model in perspective and some (the arrows) in orthographic? Thanks!
