How to fix the U/V for a sample surface ?
How to fix the U/V for a sample surface ?
(OP)
Hi,
In this sample example, the isoparam are as expected

If I change the value 5 to 0 the isoparam are switching, because the result is a planar surface and the U direction seems to be fix in this case

So, how to change the U direction for this kind of planar surface ?
The example part is in NX9
Thanks in advance

Is there a reason for the wish ?
I.e , in my view either I want a B-surface which can be deformed, or i want a planar surface because of it's benefits, but i do not want a surface that "suddenly" changes it's type.
There is the Preferences - Modeling - Freeform - Freeform construction result = Plane/ B-surface which can be set such that what normally would become planar instead becomes B-surface.
- and probably more predictable in the matter of U-V.
In my memory, the U-V of the analytical shapes are dictated by the Absolute C-sys and not by the defining curves.

For those of you who have not yet had a chance to use NX 9.0 yet, please keep in mind that while we expect people to migrate to the use of the Ribbons far accessing all NX functions, we have given special consideration to those of you who will be moving there after many years of experience using older versions of NX. In addition to the obvious, such as using the Command Finder, which we've made easier to 'find' by making it a permanent part of the user interface so that it's always available without having to open a dialog or take any special action before entering a query, we have also provided another 'permanent' function that is a place where you can still use the old cascading menu scheme for getting to where the legacy functions have always been. Note that we've not made this real prominent since we don't want totally new users going there as an alternative to using the now standard Ribbon scheme, but yet it's still there for us 'old farts', at least until you've completely acclimated yourselves to the Ribbon User Interface.
What we've done is include a 'Menu' item on the so-called 'Selection Bar', which is now more of a 'Utilities Bar' where many things have been placed, including the Selection tools, the Snap-Point options, Hide/Show functions, Work Layer widget, Movie controls, etc.
So if you've got the old menu-paths memorizes or just like to use the 'waterfall' menus to find stuff, here's how it works in NX 9.0:

Edit U/V Direction is available only with a MACH3 licence and it's not a parametric solution
Hi Tomas,
Thanks a lot
I have forgotten "Preferences - Modeling - Freeform - Freeform construction result = Plane/ B-surface" and it's a good solution
Now I can explain what I am looking for:
I am using Global Shaping by surface and now I can drive the U direction of by planar base surface by selecting the input curves in the right way
Hi John,
About the NX9 UI and command finder:
If I search "Isoparametric Curve" by example, NX open only the function in the 'Menu' item on the so-called 'Selection Bar' and explain (Red rectangle) how to find in the Curve Tab (because it's currently hidden).
==> I have just found that it's possible to show it on the Ribbon with right mouse button. So it's very helpfull
it seemed useful to explain to everyone except you of course John

IF you have the X-form License, you could select the planar surface and hit OK, it will then convert to a B-surface but keep the shape.
Btw, last time i was working with the Global Shaping by surface, ( probably NX2 time ) I came to the conclusion that it was beneficial to have the same degree- number of patches and a somewhat matching pole structure of the base and the control surface, is that correct ?
John, so what you really are saying in the above is, that we no longer should tell/ advice people where to find features, but rather tell them to type the feature name into the command finder. ?
well, this is the negative side of the ribbon bar. It is more or less impossible to write how to find a feature, other than the name of the specific feature.
The logical hierarchy is no longer there, apart from our loved extra pulldown menu in NX.
( Used by us, stubborn old users, when we know that there is a seldom used feature under the Edit dialog somewhere and I can't remember the exact name of the feature. The Options / Features in this thread are good examples of such seldom used functions.)

Tomas
RE: How to fix the U/V for a sample surface ?
NO, I like the new approach better and if you think that you're going to the 'More' panels too often, you can always use Customize to move the frequently used icons up into either an easier to access 'Gallery', onto the main Ribbon itself or for that matter, perhaps a totally NEW Ribbon where you might wish to collect all of your frequently used functions. And I've not even mentioned that you also have those currently 'hidden' SIDE and BOTTOM 'Bars' where you can drop any icon, no matter where it might currently be located. And you can even place icons on one of those extra 'Bars' or ANY of the Ribbons themselves, from the Command Finder with only a single click of the mouse.
And as for this idea that some of the less supported or preferred fucntions are now 'hidden' meaning that they have to be made active from the Command Finder, this is NOT an idea that was born with NX 9.0. We've been doing that for years, ever since the Command Finder was added to NX.
And getting back to this idea that perhaps using the Command Finder as a 'normal' way of finding something, with that in mind, we have made the Command Finder a PERMANENT part of the new User Interface, so now it's very easy to (again, excuse the pun) 'find' the Command Finder
