thanks for the reply.
i tried this in the beginning but couldn't figure out what the best 'base curve' would be.
as you can see in the image there are multiple curves i'd like all the first points to be vertically aligned. any suggestions?
Not a GH solution but if you are wanting to use the input curves from Rhino try running the CrvSeam Command in rhino to align all the curves before you reference them into GH. No rebuilding of any curves required at any points.
