how can I make a hyperbolic paraboloid surface in PTC Creo 3.0?
how can I make a hyperbolic paraboloid surface in PTC Creo 3.0? Could you answer it step by step?
I've never used Creo, but maybe this will give you some ideas.
The easiest option is looking to see if a sketch tool for conic sections exists.
Option two is a little more involved, but the surface you've described sounds like a conic section. What if you drew a cone, then created a section through it. You'd now have the desired sketch by simply converting the edges of the sectioned cone into sketch geometry.
A third option would be to generate the required curve by passing a spline through points. Does Creo support equations? If not, I'm sure there would be a way to plot the curve in a program like Excel. It could then be used to export the X.Y coordinates for the sketch points.
Anyway, it seems possible: https://en.wikipedia.org/wiki/Conic_section
