problem sets and subsets

[Tantocattivo]

Hello everyone,
before posting I searched in the forum but did not find similar discussions, so place the problem. I have a problem in creating sets and subsets. I understand better, I have a set to, a b and a set to+b which is called c. in c accoppio a+b, I realize that I have to create something in a (a hole) and I have to make it correspond with another hole that already exists in b, then what do I do? I change the part as a whole that should contain the hole and I get this message "this part has some functionsdefined in the context <insieme a="">. it is possible to change the part, but not to create external references to the components of the current axieme" . How do I solve this?

thanks in advance</insieme>

Nothing? Does that mean it only happens to me?

Don't worry, the "sintoms" are not immediate, it takes a good week, then everything you see with (justified) horror, you will see it shine like gold!
Toxins will drown your brain and fall into deep catalysts, a hallucinogenic state from which you will not recover, few managed to get rid of it!

"you can change the part, but do not create external references to the components of the current axieme" . How do I solve this?

the very few times that I put myself in such situations and I couldn't for how to redefine the subaxis I solved in this way, which I still don't like at all:
you have the "c" axieme that counts subassiemi "a" and "b"
in the subaxieme "a" that connects the part to change referring to the geometry of "b" create a sketch on which you project the geometry of "b" you need. then open the subaxieme "a" and add changes to the various parts by attaching to the geometry of the sketch previously created, which will obviously be referred to the geometry of "b". eye that if you tend to change the parts of "a" within the main axieme "c" you will be reported that it is impossible to do it: you must just open the axieme "a" and do it from there.
It is not very elegant and above all it abuses the risk and not to remember then who commands what and having to hire a private investigator to know how to change the most annihilated component. I tell you, I'll have done it three or four times and because of force majeure
iho subassiemi should be created independent of the geometry of the main axieme if not for the constraints (fixing or cinematic in the flexible subassiemi); an electric motor can go into an automatic machine, in a pump or stay in the packaging that always assists the engine it is.

unless one is accustomed to the tombacco and then gold leaves it indifferent, not only, but it touches it as well!

quiet, it happens to anyone who violates the rules (they like or not). there is also written on the help...

Hi.

 

[Tantocattivo]

thanks for the rest and encouragement! !
Now I don't have solidwrks at home, so I'll be right back in the office tomorrow. If I didn't get it wrong this is a situation that a good designer should avoid right? So what am I supposed to do? a single set where I join all the pieces of a and b? which then is not that they just join, I should do them inside the axieme and then save them as parts. However I think the error is at the base, so I have to read some guides on how to set a project well. do you have any book or guide to suggest? about the help tomorrow.
hello and thanks for the answer

are not guides, but true manuscripts of doctrine.

 

[Tantocattivo]

Do you have any titles of doctrine manuscripts? preferably in Italian

 

[Er Presidente]

No! ! !
I don't spread the devil's verb!
You have to ask those of the congregation!
:biggrin:

p.s.: since, only to know better the evil and defend me better, sometimes "bircio", it seems to me that the online suvx tutorials are made very well (the devil knows how to catch the poor minds).

I can't tell you if I make a rule, I try to avoid being in that situation, even because you don't move on.
Of course it depends on why you do a subaxieme in that certain way.
you can use reference geometry that comes from the assieme father in the subaxieme but you can't improvise it at advanced work; I didn't like it at all.
If you already know that the subaxial parts must be modeled above those of the main axieme fall directly from them and you can hook up to the rest of the geometry. in a few lines it is not easy to summarize how to behave with top-down modeling with relationships between different sub-axis, or at least I can't tonight

No! ! !

:biggrin:

[mode irriverente ON]and even if I spread it would be rather complicated to send them. the manuals where you learned du are written on clay tablets: heavy, voluminous and delicate. :tongue:
Forget it, we come to study you directly at the museum:biggrin:[mode irriverente OFF]

No no no no no, that's what really makes me squirt!! I'm practically the same problem as before. I would like to understand one thing, in a project I don't work only on it! At the end sooner or later I will have to put in my design a design of the right colleague? Will it happen sooner or later that we should join these two sets with a damn screw? How do I do it I hole if I can't make a convert entity or an offset?. I'm practically working on a bus frame and I have my set. My colleague works inside and prepared his set with the seat. I'll have holes in his seat and I'll have to do in my frame, how do I do them?

Hi.

It will seem a pathetic approach to a parametric, but in your case chairs+ bus I would not do the thing in top-down. I think the management of external references is really useful for example in the molds and in other situations where the change of a component causes cascade automatic modification of many other parts. in the case of the seat it is easier to make a puncture mask or a shared block. one will use it to make holes on the frame and one on the seat. otherwise (as I usually do) you do to handle: at the time when I go to put the seat on the frame, I catch the sketches and references with convert entities then I break all external references and requote everything. Sure does not update + automatically, but you have some problem less. swx is a bit lacking in helping in managing external references.

 

[Tantocattivo]

I don't get convinced! in this case that I talked about the seat the speech to do it by hand "may" go to me, but I attached to my frame a tide of things, I can not remake the holes every time my colleague decides for example to enlarge 5 cm a dumpster, or change the type of shock absorber or the other thousand things!!! I checked my colleague's design and it looks like he doesn't have this problem, can it be? to what you have explained is a way of working solidworks, it does not depend on how I design, right?

to me it seems more a mistake due to a kiss in the reconstruction of geometry. the sw 10 version seems to me a bit "distorted" compared to the previous ones from this point of view; so much that in some assemblies maybe built quickly and without looking at the linearity of the design (i.e. cross-references between parts) the program occasionally makes me become all the yellow details as if there was a mistake, then I reborn and everything goes in place.
Of course it's not normal, but it's not normal for you to stop making a hole in one part because you take references to other parts of different axioms.

to solve you may try to use a function of assembly (cut extruded together) to make fixing holes between different parts. when it prevents you from modifying the drilling within the part and its reuse in another set but at least (perhaps) allows you to move on.

I forgot to thank those who have already responded.
the problem cmq is not only in the holes, but also when I try to tie the sketches and then I can change the size so. Anyway, I'm gonna make a design like this and maybe the place, so you know what I have.

Thank you.

imho you have a great confusion in the head on the external reference concepts and top-down modeling. if you need a subaxieme modeled on the main axieme you create it inside that, then inside the subaxieme add a part that is related to the main axieme, then you create another one, then if to your colleague you need to build other parts that are referred only to internal geometry Solutions (for example complete the seat of all accessories after making the frame fixed on the floor) then opens the subaxieme for its facts and works quietly.
You have to do test assemblies, with simple cubes with some hole and try to build subassienas and nested parts to understand how the whole ambaradam works.
If you plan a bus that way by wronging the approach of modeling and management of the subaxis you can shoot immediately because you will not come out anymore.

Hi.

 

[Tantocattivo]

You said well, I've got a big mess in my head, but I'm going home now and tomorrow I give myself full time to this. where can I find material to erudite me?

Hello and thank you

insured non have checked the option "do not create references. . . "

from the guide:

Axioms
automatically generates the names for the geometry in reference. when this option is disabled, you can pair the parts to which you have read-only access because you adopt the id of the inner face of the parts. unless you use a component replacement, leave this option disabled, especially in a multi-user environment.

when this option is active, you automatically create surface identifiers (e.g.: face1, face2) when the part is paired. it is therefore necessary to have access to writing to the part in most cases. activate this option if you want to replace the component using the same surface identifiers, keeping in mind that you need to have writing access for the parts on which you are operating. (rename the corresponding edges and/or faces on the replacement component to couple face/bord names in the original part).

update the components names to replace documents. delete this option only if you use the component property window to assign the name of a component in the featuremanager drawing tree different from the component file name.

do not create external references to the model. select this option not to create external references when you plan in the context of a set. no mating on the place is created when creating a new component. Furthermore, external references will not be created when referring to the geometry of other components, such as when using converting entities or offset entities or extrusion entities to the top of another component. see control of the creation of external references.
