curvature of a spline inside sketch environment

[enrico1979]

Hey, everybody.
I must say that catia I like more and more even if sometimes there are things that I come from the world of pro and are inconceivable.
I'll explain.
is possible in sketch environment, drawing a spline can determine the curvature of the same and then modify it using a kind of feature analysis of curved porcupine (but inside the sketch I repeat, what certainly + logic) ?
in pro and you can have an analysis of the curvature of the spline inside the sketch, in order to be able to correct it, making it very precise curvature .
If this could not be done, then the ability to give an optimal curvature would depend solely on the experience of the designer, who then could use the bending analysis and therefore the analysis tools in general as controls exclusively of verification and not to correct any errors (which in this case are absolutely very difficult to avoid).
I hope therefore that I am wrong and that what I ask can be done, otherwise this would be a serious lack of software (although I have already seen a thousand other merits).

I think we can't do this in a sketch environment.
I usually go for attempts (lowly brigorous)
if I need to give some precise curvature at certain points
using the spline command you can decide the tangency and curvature!
Hi.

thanks for the answer
not believing it was possible I would have lost so much time looking for a featuere that does not exist.
With regard to bending and tangency, I know that you can fix it, but I assure you that it is not the same thing (for the same surface with pro and I can be much more precise, but it will also depend on the greater experience I have in that software).
I add that I know (not very well) also nx of the siemens and there it is possible to do what I ask in sketch environment.
certainly a limit that I hope has already been exceeded in v6 version of catia.

I think it's weird that you can't do it. I don't get close. try to ask for ferrezio or barlafus, or mocca, or to the prof of the noble,.. the first ones that come to mind...

Although late, I want to add that to see in real time the modification of the curved analysis to porcupine, you have to use the curve 3d command (of the freestyle module) instead of the spline command inside the sketch, this because the sketch is updated only at the exit from the same.

in freestyle certainly you do
