Mostly for what he is asking, that type of "unfolding" of a 3d model wouldnt work for his 4th axis machine.

His 3dCut has whats called "4-sided machining" so he could just generate toolpath for his actual solid model and then just index his stock with the 4th axis!

Another aproach for him could be, if he wants to "convert his Y axis to A" or something like that could be to utilize the "3d relief" type software and then wrap that on cylindrical stock (If thats the type of wrap he is after...Cylindrical stock.).

There is a free one called Zsurf that works good with MoI.
