Clearly, but if I say nothing and resize the cup since the handle has no relation to the cup but it's just a new element that I connected with the cup I wanted to know what happens.

I have not tied the handle to the size of the cup and as if it were a group that connects with another group

in pro/e you can't do it, the relationships create them automatically.
you decide whether or not to change them.
in sketchy environment, you can't have overriding or substantiated curves.
even if you create two distinct entities and then the fittings, these are however related to something (to the reference plans or the axle terna, for example).
If you're trying to erase relationships, it doesn't let you out of the sketching environment until I get it back.
 
flavio , perhaps confusion between a parametric modeler and a parametric modeler feature based.
are two distinct things, in the feature based you still have an unreliable father son relationship since you "attach" to any upstream entity.
with today's flexible modeling of creo, you can get the same result as you intended, but they are two completely different things.

If I have understood well with pro/e you can not do it because he autonomously decides how to change the profile of the handle of the right cup?
When I create what happens if I want the handle that doesn't change and the cup that shortens what it does, it makes me mistake, it still does something, it insults me what it does?
 
Ah, guys. (ozzy and max)
Is he always a "pure timestamp" modeler?
Let me explain better: if you make a change to a feature, the change automatically propagates to children? All the children?

... why do I ask the question?
because catia has a function called "local update" that allows you to make changes to the parameters of a feture and see the changes applied only to her...
Of course, the model goes out of synchronia... but it is very useful in the moments when you have to do so much "try & see what happens". .

Let's say that the parametric surfaces for the style should have any other operation... :redface:

beppe, in fact here we have not touched the topic isdx surfaces (generated from 3d curves) or rex (free surfaces starting from a stl data or network of curves or points).
in this case your starting date is not a sketch, and then the changes do not make it on the odds but on the form, even if it is always possible to bind the individual surface to precise distances (planes, datum ... curves etc.).

Yes... I read the first posts and your answer with document... I didn't see the question.
obvious your answer was perfect for the mail question... but since I had not read the question I could not understand that the answer was adequate. . .
Of course, if you read the questions before you answer... All the questions... I wouldn't have given that answer.. .
Therefore, the conclusion is "read all the questions before formulating another" otherwise the answer you will get is not related to the question you have asked.

I have the alzhaimer... :eek: or it is only that I am overwhelmed by events and if I think of it sclero. . .

as our parametric (alpha) is structured, there is no need to do this.
practically models in a completely free way without focusing on the speech you are using the parametric then if you have to change something you do it by re-editing the features in a "direct" way or through the tree.
from what I may have guessed I also create should work this way
it would be nice to open a new thread in the challenge area to see the various alternatives of associative parameters.

all parametric modelers work so...
the difference is that nx (but I also believe I create... uff, how hard to use this nouvo name...) is a timestamp, so it has the features in sequence... While catia has them as a graph (even ideas was so).
Ultimately, for the user, the difference is that in nx, unless you go to "make current feature" at the beginning of the tree (I in pro/e v19 I called it "trim mode"...) a change to the features 10 stacked (and then recalculate) all the features daughters... While in the casket, if you want, you can ask for the "local update" only of the 10... then of the 15... then of the 25... then again of the 10... and forward... and eventually you do a total recalculation (with the fan)

in creo (I also struggle with the new name), in the rex module and in the isdx module, there is the possibility to break the bonds (or to detach) of the individual surfaces or curves.
But you have to be very careful about the changes, breaking the bond, if you go to change a contiguous surface, the one that was an dependent surface no longer changes unless you restore the bond (or bond).

It's something I use at the end of the process.
when you have realized your roof or your hood or your door, the file may be very heavy to handle (typically there is also a stl from hundreds of thousands of triangles).
if the work becomes very slow and unmanageable, cut off all the surfaces made and the file becomes much lighter and more stable.
of course caution wants this to be done on a copy of the file.

and no, I wouldn't say, if you leave unsolved feature, before you go on, you have to solve it and then you can switch to the rest (upgrade).
with the surfaces this does not happen the update however happens and if you want to put in place something not up to date you can intervene in the middle.
This is at least what I understand.

Here's my question, I try to do it as simple as possible.
model a cup and then then his handle that I don't tie to the size of the cup what happens if then I change the parameters as you see from the image? (attention that however the handle is connected to the rest of the cup)

and what difference is it if I parameterize it through solids or through surfaces?

This cup took me... I did one in nx, tell me what you think.http://www.youtube.com/watch?nr=1&v=ihm1iyiq9gw
ciao
 
Sto nx 8 looks really powerful.
I used the 7.0 for a few weeks and I have to say that there approach was wonderful.
