Thanks guys, both posts one in the same. I can see how Ferrari could do it but I'm trying to do it with current tools I use; I'm sure there is a way.
Below are some examples of what I'm hoping to achieve:
Also a skippy file of some base shapes:
I'm keen to see some different ways to achieve this.

So here's progress but not how I want the outcome...
I thought I may have to create segments of the fabric and make them components seeing each side will be the same however when I do that I end up with hard edges where my shapes connect.
Its really got me beat how you do this. Maybe I should be creating it from the ground up rather than around the edges...?

IDK how to do this for the precise mathematics but you get a different shape if you have a curve at the bottom edge. Not sure this is what you are after.

.
a square perimeter with a rounded top and a drooping mesh using curviloft would be something like this:

This how Ferrari deals with it, for info.

Hi:
I fiddled with this yesterday. I did it two ways. When I did the deed by sections, selecting each curve in sequence, and mirror copied the result, I noticed the mis-shapened circular opening. When I selected everything and then activated the tool, I got a more regular opening. Segment count and size of segments in the curves do matter for more regular surfaces, as well as degree of curvature. My "good" result still had too much torsion/warpage in the finished surface. Did you see this too? -

Thanks for giving it a go, mate! Normally I would expect the outer edge to be exactly how you've done it but the client wants to be able to fit drapes to the edges to close it in at times....

That's pretty much how I had attempted it also, Jeff however the 4 'hips' will actually be welded and stretched so they won't appear to have hard edges....
cheers for the input though!

That's close, gillies although the surface on the outside of the apexes differ from the inner. seems 'warped to one side.
Getting close though!

I'm not really sure about what shape it is you are after but this is Extrude edges by rails.
I don't know how you work white on white? sends me blind.

soften the edges after arraying. (or gap the array at the hips and fill in with an actual rounded surface)
the main point being- if you use that outwardly bulging edge of the top ring as part of a networked surface and the opposing edge is straight, the bulge is going to carry throughout the surface.. if you want the surface to sag in the middle, you'll have to do something like i showed (if using curviloft or any of the 2rail sweep plugins)..
maybe with soap skin& bubble you could get the sunken results as it has the pressure adjuster.. -
@utiler:
I used Curviloft by activating the "tent" icon. -
So this is where it ended up at but still not convinced its the best result.
-
hmm.. i'm not entirely sure what shape you're trying to get.. this latest version is different than the one you first described (or more likely- i misinterpreted before)
is this what you want? if so, it's easier to draw than the other one i showed.. i'll tell you how to do it if it's the right shape
-
I don't mind that, Jeff?
Please tell me more.... -
