Hi there ive been trying to make a model but am struggling with the design I think this shape could work, is anyone able to make me this shape, thank you !
Is that a parabola of revolution / a paraboloid?
If you can create the parabola, you can then use the FollowMe tool to create the solid shape.
See How to draw a parabola and its focal point? for a Bezier curve plugin to create the parabola.
Or the plugin CurveMaker will draw one.
There’s also a plugin nz_parabola on the Extension Warehouse, and a trial is free.
For example (drawn with CurveMaker):

If you can be more specific about the shape, I could try to draw it for you.
If you aren’t worried about the mathematically accuracy of a parabolic shape, you could just stretch a sphere.

…to make an ellipsoid.
I’ve made a parabola before. It’s on my list of little YouTube videos to make. No time right now, but here’s a visual set of steps.
- Make a cone
- Make a vertical plane
- Rotate it to match the slope of the cone
- Move it to the center of the base
- Intersect the plane with the cone

Actually, to look at it, the ellipsoid might be a closer match. Sides of a parabola never become vertical in slope.
