@Mohammadz ,
This is possible to achieve. Here’w one way you can do it:
multiple profile solid loft.dyn (12.2 KB)
Since you have a big number of elements, I thought it would be beneficial to avoid having to select them… In the screenshot above you can see that the script makes one path from all the reference curves and sorts the profiles along that path automatically.
Now if you try this with the .Rfa you posted in your previous post, it wont work because your profiles are not on the reference curves. They are very close but not on them, so the loft operation fails.
