maya - Python script to uncurl or unfold geometry along a curve -

i have been on internet trying find answer 1 , i've reached end of patience. trying achieve pretty standard bend deformer difference want unfold along pre-defined curve. there literally hundreds of tutorials bend deformer doing same thing, unfolding along flat plane none on how along curved surface. have tried paint effects control curves no avail , baking bend deformer geometry curving afterwards. last option didn't work no longer had control required. seems search way through mel or python script , wondering able help?

something this? constrain -> motion patch -> attach motion patch + flow path object
