Hey Solidworks gurus, I need some help. I have this tube that I need to draw a line at a 45 degree angle that wraps the surface all the way down it. I couldn't figure it out using helix (assuming that's for circle sketches only), or drawing a sweep. I figure one of you guys would know a quick way to figure it out. I need it to be on the surface of the part, but I'm not sure how I can complete this. Any help would be appreciated. Thank you.
