Sphere pattern calculator

ADOESNT WORK I NEED TO FIX IT RAHHHH A calculator tool to help draw pattens for spheres (for fabric, foam, paper, etc) by hand!

diametre:

must be a number above 0.0 to 100000.0

Number of slices:
(how many pieces are needed to make up the shape, more slices = possibly more accurate but more seams)

must be a whole number above 0 to 200

Numer of segments:
(how many measuremants are needed to draw the pattern, more segmants = more accurate but more measuring)

must be a whole, even number above 0 to 200

Stretch:
(How stretched the sphere is)

must be a number above 0.0 to 1000.0

Max number of decimal points:

Must be a whole number from 0 to 16

Units: (optional)

Show cumulative segment height

Note: image not to scale! just for an idea of where the measurements are :]

Text Version:

Instructions:

Input dimentions above
On a piece of paper (or what have you) draw a line the width of 'Height'
Along the 'height' line add a notch every 'Segment height'
Then, perpendicularly, draw a line at each notch with the cooresponding width (half on each side)
Join up the ends of the height line and each width line with a curve
Cut out ya pattern!
Cut 'slices' number of your material, and join em up using the width lines as graduation marks!
yayyy ballll (hopefully)
