 The parabolic transition segment is modelled with _IfcPolynomialCurve_ with certain restrictions. The size of the attribute _CoefficientsY_ is restricted to 3. The quadratic term is on position 3. In general, the _CoefficientsX_ size would be restricted to 2 and values specified as [0, 1]. This produces the following result:
 
-y = CoefficientsX[3]*x², where other values in _CoefficientsY_ are 0.
+y = CoefficientsY[3]*x², where other values in _CoefficientsY_ are 0.
