NX - big failure
NX - big failure
(OP)
a new plane is created, say 80 deg to x-y plane, and passing through x-axis (zero distance form x-axis).
A sketch is made in that new plane.
Later on the plane is rotated, say 20 deg, more from x-y plane, so it pass x-z plane.
The sketch flips without role, all other things connected to that sketch gone too, ...
Resultant vector = All works, months spent, has to be redone, business lost due to time, ...
This additional rotation should be very simple operation within any software, however NX canNOT do it.
No further comment needed.

You can make such plane and some polygon on it quickly, make additional turn and you will see a big mess. The whole point is that it should be a simple and robust operation, but is not.
RE: NX - big failure
Out of curiosity I made a test on a version 7.5 involving "such plane and some polygon on it quickly", and did not find any errors. Obviously it does not mean problem does not exist, but we need more information from you to replicate it.
Meanwhile I can direct your attention to the following point. You mentioned that you put sketch on a plane and then rotated that plane. I personally would discourage you from putting skecth on a plane, let alone rotating one. What I recommend is to create an offset CSYS which would rotate against axis of the original CSYS and put sketch on it. This well might improve things for you.

RE: NX - big failure
it is not the matter what you did, no array and multiply sketches. You just did a copy. It is not the way to go...
RE: NX - big failure
Not the way to go where? You didn't explain us.
How does the hint with the offset CSYS look to you? Can it help? If you haven't used offset CSYS before, mind that if supports not only offset but rotation as well.

I am using one sketch to locate the second, then use the second as a datum, ....
I will try coordinate systems, but slim chance the things will improve.

RE: NX - big failure
I did it with coordinate system rot. and sketch did not flip. My problem is now that for any my plane replacement I will have 3-planes and 3-axis.. Soooo many will be around. Dealing with all of them will ask for time I hardly can find. But looks it is the only way.
How to insert picture here?

RE: NX - big failure
"You don't have to deal with 3 planes and 3 axis, because CSYS is a single entity. Otherwise, can't see much of a problem dealing with model entities. Do you use layers and reference sets? If you don't, you must urgently start to."
please say how long you are with unigraphics?
Are you working with John Baker?
[b]John, do you agree with above?
RE: NX - big failure
CSYS is a single entity in some ways (modeling feature in a tree), and multiple entities (origin point, planes and axis) in another. That's quite a unique feature which can do you a lot of good if you make friendship with it.

RE: NX - big failure
As for you not finding the time to make a simple example part, well how badly do you really want help (you've already stated that you've lost months of work or was that just so much hyperbole)? Your original post reads like a RANT, what with the title you chose, "NX - big failure", and then your closing statement, "No further comment needed.", like you were not really expecting any help. If that was the case, why did you even waste your time posting anything at all? Eng-Tips is a site where people come to get and/or offer help, it's not for venting and then when you're offered help you get righteous about how you KNOW that there isn't a solution and when someone does provide you with one, you jump down his throat implying that he's somehow part of a conspiracy or something. If it's really true that you've spent months and it's affected your business, then I would be a bit more appreciative when someone offers you help, even if it requires a bit of extra work, or when someone actually DOES give you something that works.

RE: NX - big failure
1. Flipping sketch shall not be a part of professional and high-end program. I expect from a such program to free me from software problems and my concentration should be on the engineering problems.
2. I am not professional internet guy with thousands of posts and hours, I am neither so familiar for the procedure to get a picture on this forum. I am looking to spend smallest possible amount of time on internet. as and I am looking for a bit of good help if can find.
3. I am very selective on accepting advices, especially when I sniff that a young is around. Their advices I do not need no matter good or bad.
4. Thank you for your advice about the coordinate system, it might works for me (it did not flip the sketch).
RE: NX - big failure
Any thoughts on how to prevent?

It was actually me who gave you the advice about CSYS.
Sketch flipping is not a part of NX per se. It is wrong use of NX that might give you that effect.
But it is the case with ANY software - if you don't know how to use it, you will get errors every time.As you might have noticed, when used properly, NX is well capable of giving you the correct answer.www.cadroad.com
RE: NX - big failure
Your loss. A fresh perspective on more efficient methods to use the software should always be appreciated. A young user may not have the drafting or design experience that you do, but may learn how to best use the tools given better than someone who is stuck in methods that have always worked for them in the past.

Note that if the datum csys is only used for the sketch, you can make it "internal" to the sketch. This will remove it from view and the feature tree until you need to edit it or use the "make datums external" command.

RE: NX - big failure
Create 2 lines (basically x and y axes) that are perpendicular to each other, position them and fully constrain them, and then constrain your sketch w.r.t. these 2 lines. With this, we can avoid referring more than two references for a sketch.
As someone pointed out, there are always better ways to use software while designing your product, it is just a matter of adapting such better methods.
And if we are dealing with angles or lengths that flip on either side of a reference/line, we are likely to end up in mess. In such cases, we should create a Dummy reference that will allow "change of angle/length" in Only One Direction! For example, if we need a line that changes to either 70 and 100 degrees, then refer a line at 60 degrees instead of a line at 90 degrees.
