curve defined by an equation

[enriquelvarez]

Hi!

I'm trying to draw a parabolic curve and I'd like to know if there's any way to do it by introducing a table of values(x and y) or by introducing a formula as y=x^2

Thank's very much for your help

That's a very simple formula to setup.

Do you know how to setup parameters?

The Parabola y = x² is a unique Conic, and is a curve that can be created direct in Catia:

Insert => Wireframe => Conic.

A simple example is a parabola that starts at (1,1,0), ends at (-1,1,0), has a vertex at (0,0,0) and a directrix at (0,-1,0) - this is the tangents intersection point. The Parameter for a parabola is 0.5, parameter values [0>P<0.5] are elliptical, those [0.5>P<1] are hyperbolic.

The only difference between any parabolas is the Scale, so whatever values you have for the parabola dimensions, the point values can found from y = x² ; the tangent intersection point is always minus the 'y' value of the start and end points.

check the online documentation for Creating a Curve From Its Equation

Then if you have question on this, tell us more about your problem, but everything is detailed in the DS doc...
