Doesn't look like we have a choice..

hey - you can call it anything you like for me - but Bob asked what the shape was called - now I am not particularly clever, but I am sure of my maths.. if you want to define it some other way be my guest

[pauland]

Maybe you aren't familiar with the term 'Boboid', symmetrical, straight on the vertical, curved on the horizontal, a subset of the 'Ovoid' clan.

I read it somewhere..

They forgot to mention the 'Boboid'.

I think stadium fits the bill rather well, unless it's The Caketin stadium in Wellington NZ.

Hi Bob.

I'm not sure what you mean, when you say "...you wouldn't believe how difficult it is to draw precisely..."

I drew it in a couple of minutes.
Am I missing something, that I've not understood?

[ss-kalm]

... you wouldn't believe how difficult it is to draw precisely, despite using Xara's guides and snapping ...

Why wouldn't you use a rectangle with curved corners ... i.e. Rectangle 10 x 15 with corners with a 5 radius. Unless I'm missing something too.

@Keith, well it just shows how dim I can be, the rounded rectangle option never entered my head!
@Rik, it's obviously me, I had difficulty aligning the shapes I kept getting unwanted lines as a result.
@Steve & Paul, I think that "Lozenge" also describes the shape, yes?
Bob.

Just to add to the mix - a superellipse - http://mathworld.wolfram.com/Superellipse.html: with r > 2.
Here a=1, b=1.5 and r=3.5: http://www.wolframalpha.com/input/?x...%3D1.5+r%3D3.5

Danish mathematician Piet Hein heavily used it and had a superellipsoid dubbed the Superegg.
