How to create a 3d surface using curves


surface using curves
how to do it using grasshopper , I have tried to loft it and extrude it both are not working, unable to seep it along path also.

3. Attach minimal versions of all the relevant files

Use the 4 outside curves and 4 inside curves, respectively, to make 2 Loft surfaces. Then use the top 2 and the bottom 2 curves to make 2 Ruled surfaces. Then use Brep Join to join them all together. If your curves are reasonably well defined you should end up with a Closed Brep.

Depending on your file, you might want to flatten the input of the loft node

Too many lofts maybe. Needed some grafting earlier on. Anyway.
