But seriously, I've been using SU for a few versions. Since maybe 5 or 6? I use it for recreational purposes. Last year I got sidetracked into Kerkythea but then ran out of patience and went with Podium. I want to learn about different techniques and available plug-ins. I can do anything that doesn't involve curves/angles through all three dimensions... a cabriole leg w/ claw foot is beyond my skills. Or a footed bathtub, for instance.
The octagonal turning in your last lesson was interesting too, because I didn't anticipate the distance differences between a circle and the octagon. For instance, the way I did that one was to build a profile, Follow-Me around a complete circle, then draw an octagon a Push it through the shape to flatten out the top and bottom pieces and create the interior. That gave me 1/8th of the shape, I just assembled from there. It took some trial and error because I kept underestimating how much bulge I needed in the profile to crop the top and bottom while avoiding the turned section in the center.
