I split a mother curve into 3 child curves but I don’t remember the cut points. Now I want to place the child curves back exactly on the mother curve in Grasshopper. How can I do this so the position is 100% accurate?
Each curve has a domain. That domain will not change if you split out a part of it. So the start of the domain of your child curve should still map to the same parameter on the mother curve.
whats that mean how to check domain
does this help:

yes , thats clear i understood but my small curves are rotated and moved.will it work if thats the case.
if they are rotated, take the parameters of the start and end of the curves and orient them based on two points (assuming the curves are in the same plane)

First of all, those are surfaces, not curves. Second, the surface is not a part of the bigger (poly)surface. The polysurface is made out revolved surfaces, the smaller surface is a generic nurbs surface and its radius is different from the radii in the polysurface

yes brother i know those a surfaces, but i am gonna extract top curves from those surfaces.
-
second the surface can exactly fit in the polysurface at certain coordinates(which i wanna do).
-
is correct the length of smaller is different that what i mentioned in the start of this discussion.
check the above images i placed manually. i know very well it will fit somewhere in the bigger curve, i dont know how to do.
no, not possible, at least not the way you asked for with the curves. The surface is not a subsurface of the polysurface. The best you can do is fit a circle through the surface (roughly r5450), and then align it with one of the r5500 surfaces in the polysurface.
