Helical (Spiraling) V-Groove along length of shaft?

[patm1313]

I'm trying to make a cut V-Groove along the length of a shaft but while I can make the V-Groove parallel to the shaft, I can not make it spiral around the shaft. I know it can be done- I've seen it machined before. But I can't, for the life of me, find out how to do it in eMS.

The CAD cannot yet model that but you can use Comments To Machinist.
