@Reynolds, I found this equation CurvePoint = (A*W1*(1-t)^2 + B*W2*2t(1-t) + C*W3*t^2) / (W1*(1-t)^2 + W2*2t(1-t) + W3*t^2) My Python interpretation is: p = (a * w1 * (1-t) ** 2 + b * w2 * 2*t (1-t) + C * w3 * t ** 2 ) / (w1 * (1-t) ** 2 + w2 * 2*t (1-t) + w3 * t**2) Would 2t be 2*t? Do I have the rest correct? Also, what would the weights (w values) be for a circular arc? Thank you.
