Hey so I’m trying to create an ellipsoid with adjustable radius in all 3 directions. I have created two curves as seen in below picture, I’d like to how can I create a smooth surface? [Screenshot 2024-08-13 084222]

Best to create them mathematically. Once to understand how they work, you can fine tune the shape as desired More examples available here [ellipsoid] //Dome Transformations n = 51; x = Math.Sin(0..90..#n)<1>*Math.Cos(0..360..#n); y = Math.Sin(0..90..#n)<1>*Math.Sin(0..360..#n); z = Math.Cos(0..…

Hi @rajeshjamariya16 try surface by loft [Skærmbillede 2024-08-13 064150]

Hi, That just joins two profile. I need a smoother profile to create a 3d ellipse, see below image [Screenshot 2024-08-13 101610]

I’m sorry it actually does create what I want lol

sorry another question!! I have mirrored those curves, how do I close that final loft? [image]

try something here [Skærmbillede 2024-08-13 064150]

as you can see the profile is not smooth on this side, like the other side. I tried adding the first curve in the list but I guess it just can’t self intersect?

yeah probably better with revolve…not sure

with revolve I won’t be able to adjust it’s size in Z direction. do we not have any work around or any other way to accomplish this?
