You can create an involute profile(datum curve) by creating a curve from equation. r = base radius ang = t * 90 s = length of curve t = system parameter that varies from 0-1 s = (PI * r * t)/2 xc = r * cos(ang) yc = r * sin(ang) x = xc + (s * sin(ang)) y = yc - (s * cos(ang)) z = 0 If you know the base radius use it in this equation and you will get a curve.
