multiple surfaces with isoline without retract

[jeff.brower]

How do you use isoline to cut multiple surface but have the path travel across all the surfaces without retracting, or cutting one surface at a time? Or what surface machining approach fill follow the surface directions so the path is continuous from one end to the other?

I would give this a try.

Thanks, that's a good solution but sometimes 2 curves doesn't work well. Hoping for another solution to driving path along multiple surfaces in an isoline style.
