Hi all,

I am trying to model a parabaloid which I can do by revolving a parabola around an axis but I have yet to figure out a way to draw a parabola. Is there a feature for this? If not, does anyone have tips as to how I can do so? (I am quite new to the modelling software)

Thank you!

Draw an ellipse. Bisect it. Revolve it. Subtract the desired shape from it. Use the Shell tool.

Please guys . There is no way you can bisect an ellipse to get a parabola . A parabola is not a closed shape . the focal point of a parabola is at infinity . Hence, you can not cut and ellipse and get a parabola.
