Stretched Sphere - challenging edge distances (reversed)

[Morne Erasmus]

Hi all

 

I have a sphere (hemisphere) that in plan has been stretched in the X and pinched in the Y, so it looks like an ellipse in plan.

Then in front and left view, it has been tapered, so that the sides almost become vertical, then the top curves in to the middle.

 

Great, shape is correct.

 

I need only the horizontal edges, BUT here's the catch:

Due to the strecth/pinch/taper, the linear 3D distance from horizontal edge to horizontal edge from the bottom is small, then becomes further to the top. I need it the other way around. I need the horizontal edges closer at the top and further at the bottom.

 

 

I tried with soft selection, but that doesnt work too well as it also then selects the vertical edges which in turn bends my horizontal edges down, making them curved and no longer horizontal.

 

Would be nice if there was a way whereby I could just shift the edges up or down.

OR,

conform a spline to the outside face of the sphere, then array it up over the sphere, becoming closer as it get to the top

 

By the way, I simplified it here so you can see. My actual object has a lot more horizontal edges

Hi,

 

In this case I would recreate the object using the hemisphere as reference and with that you can also fix the single vextex problem that you get with that. Then you would get total control over where you want edges.

 

The other option that you can try is using NURBS, but personally I haven't worked more with that so can't really say how you can get the best result you are looking for. When it comes to Surfaces I usually revert to Rhino modelling as it gives way more control.

Do you need the geometry/mesh or just the edges? If you only need the edges you could just slice, or arrange some planes so that they intersect where you need them to and do a boolean to get the new edges?
