Hi bogdan catalin,

to have a real parabola you have to:

1 - create a curve by equation (see https://learningexchange.ptc.com/tutorial/394/creating-a-curve-from-equation)

2 - make a revolution of that curve

PS: to have a parabola

     R=123.456  (radius of the parabola)

     K=-1 (conicity factor of parabola)

     Y=((X^2)/R)/(1+sqrt (1-((X/R)^2)*(1+K)))

     Z=0

Regards
