Agreed. I'm wondering if you have a mouse with a scroll wheel on it? If not, go get one. Its an absolute must have for working in SketchUp.
Well. guess what some have a scroll mouse. I don't like to make smart comments however have you traced curved lines in 2 mm increments try for yourself even at a large scale the jumping of the lines are very annoying.If I have overlooked anything correct me. I think the comment about the scroll mouse was a valid comment but the person who has asked that question first sounded like he knows what he is doing.
