Hi,
Do anyone knows any way to draw an hyperbole, guys? A parabola or an ellipse is not enough
Cheers & thanks in advance.

RE: hyperboloids
I assume you meant hyperbola. Hand enter the data into the curve feature. Generate the data in an exteral program, save that data as a text file then create a curve through XYZ points by using the import file option. You might be able to do it through a macro? I did a quick look through API help and did not see anything for generating a curve through points so maybe not? You also may be able to use the spline tool?

RE: hyperboloids
Thanks for your suggestion. Sorry for my bad English. I was talking about an hyperbola.
The problem is that I would like to model some optics and parametrize the design of a telescope mount. The idea was to parametrize the optics so that the mount may be adjusted quickly as soon as the optics layout is changed.
This would be difficult with the solution you mention (interpolating the function in an external sheet), but is one of the best solution I can see.
Another solution is to use an equation that does the same computation but inside SW and adjust it with spline. Not perfect but may work.
I wonder if SW2006 or following versions has this feature (hyperbola) or a way to define a generic curve by its equation, that could be more interesting when you have to parametrize a profile with very high accuracy.
Cheers,

RE: hyperboloids
Well depending on the number of points to make the curve, you could either use a spline or a curve through reference points. Dimension each point and then put the point dimensions into a design table. You can write your equation in the design table to update the point dimensions. If the equation is linked to some parameter in the model that changes the curve, then by allowing model updates in the design table, all you would have to do is open the design table so the curve point info would update and then close the design table.

RE: hyperboloids
Otherwise, calculate pint locations and aproximate with a spline.
RE: hyperboloids
There has to be an equation relating the parameters of the conic and the coordinates of the plane - although I don't know it off-hand.
