Thread: Does any know the name of this shape?

Hi,
I think you will need a drawing program's Bezier curve. Bezier curve - Wikipedia
Cheers

Thanks Austastar.

Unfortunately I wouldn’t know where to begin with a computer.
Doing it with a compass is my only option but thankfully it doesn’t have to be precise.

Hi,
Ok, if you have a bit of room for error.
Take a couple of 90 degree angles inwards from the four sides of the 'square circle'. They should meet at the 4 points you need for the compass. The corners will be a bit sharp, but could be hand shaped.
Cheers

Try squircle. It may not be that however looking at some of the shapes I found - same but different.

It may be a case of tracing around what you have there and on the same tracing paper, physically matching the diameter of the curves with a compass and measuring the radius of the curve you sorted out.

You’re right, it’s a squircle! Learn something every day.
if I enlarge the curved portions of a squircle I’ll end up with what I’m looking for.
thanks for the help folks, I’m sorted.

how can a compass make it?

Four semi-circles from four points.

Draw a square. Rotate 45 deg. Using a compass draw a circle on each corner of the rotated square with the circle radius being equal to the diagonal length of the square. The area inside the overlapping circles is the shape. That is the shape more or less. Proportions of the semi-circle can be done by extending the radius outwards from the corner of the square.

looks nothing like it

found your old etch a sketch eh?
