Modeling Cloudshape

Dear All,

Hopefully someone can help me out with this one. I want to model a cloudshape like the image attached below. I have no idea where to start or how to do this. I have good knowledge of Rhino and grasshopper.

If someone has any sugestions please tell me.

Thanks in advance,


If you need it to be nurbs then control point editing is probably the best way to go.
You can make a sphere and rebuild it so it has more controlpoints, then point edit it.
(Then you can rebuild again with even more controlpoints and add details)
Make sure you put the seam underneath or at the back.

Thank you verry much! I undersand what you mean and it would do the trick but I am not sure this is the way to go for me. The model i am going to make is a much much bigger cloud than this one. It would be to much modeling i guess. I also want to studie the final form so I was looking for a more automated proces. Do you have any idea on how to do this?

kind regards,


Ah yeah and i don’t really need it to be NURBS if that’s any help.

Ok, it made me think of metaballs, so I did a quick search on Grasshopper Metaballs and this came up:

Good luck from there! :slight_smile:
