Unfortunately, my Adobe Photoshop LE doesn't feature such a rich collection of tools (you cannot even create a circle!). Fortunately, most of the tools you have a replicated nicely in Serif's DrawPlus and PhotoPlus software... :)Now, again... it ain't necessarily so! :) "Lemme 'splain, Lucy," as Ricky Ricardo used to say.It may well be that the coordinate system in my little project is #####-eyed, but the reality is that the little yellow arrow is the longitudinal axis! If I align the z axis (blue arrow) the way the docs say, the durn prop rotates around a vertical axis... :)Thanks for the lucid explanation of the various coordinate systems though, I'm gradually piecing it all together!
