How to reproduce the same CATIA surf in NX8.5 ?
How to reproduce the same CATIA surf in NX8.5 ?
(OP)
Hi,
I would like to reproduce the same CATIA surface in NX8.5


I have succeed with bridge surface but the Tangent Magnitude is 1.45 instead of 1 in CATIA (part NXBlend)

But with another example (part NXBlend_2) the Tangent Magnitude is always setted to 1 in CATIA but 1.25 in NX !!!

TIA

Does this even make any difference as your end result is the same?

Thanks for your answer. I am not a CATIA Expert and I don't have CATIA on my laptop
What's the difference between NURPS and NURBS ?
It's a little bit difficult to explain. My Customer try to adapt in NX a code developped in CATIA. And the Tangent Magnitude (Tensions in CATIA) must remain to 1 ?

We don't have the same results with the same default parameter in NX and CATIA (Tangent Magnitude = Tensions = 1)
The body()"Surface CATIA" is obtained with tension=1 within both parts in CATIA
My problem is that in NX8.5 "Tangent Magnitude" must be set to 1.45 in NXBlend.prt and to 1.25 in NXBlend_2.prt
Maybe should it be equal to another value than CATIA but the same in both case !!
Do you agree with that ?

Now IF we could find someone who was fully-versed in the mathematical underpinnings of BOTH CATIA and NX, at least with respect to surface creation, than perhaps we might learn why what you're seeing is what it is. But barring finding such a person, this may have to remain a mystry, as it were.
