We have parts with complex shapes which can only be defined by generating a curve based on a mathematical equation. For example: sine wave, parabola, hyperbola, etc. How can we command inventor to generate a sketched shape such as this?

I don't have IV anymore, so I can't give you specific help on the newer versions. However, I have a lisp routine that will generate a parabola. IOW, you can run the function in acad, generate a polyline, and then import that into IV and loft it, sweep it, etc.
Thanks for the quick reply Ed. If you wouldn't mind sending me that lisp file I'll give it a try. At least it will give a place to start.
I'm new to this whole forum thing. Can you get my e-mail from my profile?
From what I gather you have to draw the geometry and then apply equations to drive dimensions you'd put in.
Take for example a parabola...
Draw a spline with 3 points. Dimension between the 3 points in a matter that permits the lateral distance to be equal from each endpoint to the centerpoint, and then apply your height dimension...
Like this...
Another suggestion, use Excel to generate the points, and import the points into Inventor. You should be able to put a spline through that and get your curve.
Don't know if that absolutely solves your issue, but it's at least another option.
