surface creation

Hi,

I am trying to use grasshopper to create a geometry from points. This geometry needs to be as precise as possible and not present gaps or severe discontinuities between different surfaces.

My current challenge is to create a surface between a nurbs curve on one side and another profile that consists both on a nurbs curve and a line on the other.

You can see there are already two surfaces(both created by loft).

I initially thought I would be able to join both curves on the left side of the gap between surfaces and do a loft. Somehow it does not work.

What do you suggest? I really need a flat surface (the one painted in green) and I need the connection between the two surfaces to be as smooth as possible.

Thank you so much for you time

Hi,

Is this good enough?

Even better if you also split it on the top angle into 3 pieces.

Also, use integer parameters rather than number parameters to store the index numbers.

Hi Vicente,

I do think this should do the trick. Thank you so much. I have tested also with one more split as you suggested and it does seem to improve the connection surface.

And in the meantime I have also moved to integer parameters.

I will, in the future, try to generate different geometries by manipulating point coordinates and then create a mesh and send it to a FEA software. I guess only then I will know for sure if this does work as desired. But it seems to a quite good approach.

Thanks for your time and availability.
