Equation curves

[dwages]

Is there a way to graph a curve using an equation over a closed interval in Inventor 2012?  I know I can draw a spline through points that are solutions of my equation, but this does not guarantee that the curve is the graph of my equation.  Any help would be grealy appreciated.

In 2012 you can bring in as many points as you need calculated in Excel and have Inventor automatically create spline.

You might start with a very large number of points on one sketch.

Then try again on another sketch with just a few calculated points.

Examine the difference of the curves in reference to the tolerance of the actual manufacturing process.

You might find that it takes a surprisingly few points to generate a curve well within the actual manufacturing tolerance.

In 2013 you can enter equation curves directly.

Thank you...I tried this, and it worked well.
