If you're using the line tool for straight lines in technical illiustration, do you have any curves that you have to adjust using the mesh tool? I use the line tool for straight angles and such in my backgrounds.
I think AI also has a curve tool. But in any case, you can always add new anchor points to a straight line or add curvature to it later on. The mesh tool works for shapes/shaded regions.
