triglyph Posted February 6, 2010 Posted February 6, 2010 I'm trying to draw a greenscreen cyc wall: curved where it meets the floor and three walls so it's compound curves. Can't figure out the sweep command. What does "alignment" and basepoint do? Every time I sweep the line, it's all screwy and not aligned like I want it to. Then I can only rotate in one axis, so I can't get it where I want it to be. Quote
kencaz Posted February 7, 2010 Posted February 7, 2010 Sweep can be a tricky command especially in alignment and rotation. I try to always orient my USC perpendicular to my sweep path to make it easier to orient my sweep profile. Align "will" put your profile perpendicular automatically , however, you will still most likely have to rotate it, which can be difficult if it's not on the correct plane to start. That's why I prefer to orient my USC instead. I always cut threads this way. It can be a trial and error prospect to get it rotated correctly if your working with an unusual profile but you'll just have to play with the commands a little. Here is a link that kinda explains it well... http://www.cadalyst.com/cad/autocad/circles-and-lines-housework-made-easy-5839 KC Quote
