Chevron around cylinder

[tssteel83]

Hello, 

I have a project that I need to draw a welded chevron around a cylinder. Tricky part is it is only part of a chevron wrapped around the cylinder and also mirrored on the opposite side of the cylinder, as well as having the 7 runs of weld pictured. Picture attached, basically as drawn but mirrored both sides.

Split the cylinder surface with a sketch line and sweep the weld profile along the split line, then mirror.
