booleane e catia

[opua]

hi to all, the company where I work recently started to use besides pro-and also catia, as between us designers only one knows the software in question, often working with boolean, I ask you: according to you it is better to use the "classic" modeling for example to get a hole to perform a cut, or create a solid to then extract it? I thought the Booleans were obsolete, succumbed to such advanced programs.

depends on the type of modeling you do, for very simple details (hole plates, levers, small boxes..ecc) you do not need to talk about boolean, but when we start talking about details like aluminum die castings, or plastic injection parts with a high number of details, I can assure you that the boolean allows you to fragment much better the structure of your particular, also because you have to see this not so much in the phase of modeling.
so I would say that more cad has evolved more boolean uses.

... I ask you: according to you it is better to use the "classic" modeling for example to get a hole to perform a cut, or create a solid to then extract it? I thought the Booleans were obsolete, succumbed to such advanced programs.

clarification: to create a hole use the function "hole" and not pocket. I'd better exploit all the advantages of the case :wink:

 

[ideacad]

I agree with you falonef.
The hole command, offers a lot more control than the classic pocket.

Booleanes are normally used by those who design die casting molds. the designer sends the model of the piece to print and the moulder creates the 3d of the mold with a boolean of subtraction.
in the design of pieces from "zero" it is very difficult to have to work with the boolean, except for particular uses (see import of body of braised raw pieces to then perform finishing work) or excessive complexity of the model.sicuramente to perform a hole or any pocket with a boolean of subtraction not only is a useless loss of time, but also denotes the inability to work in 3d.in 15 years.

windreef... heavy as statement. Did a boolean fall on your foot?
when you do operations we call them emptying (tasks, tabs, groove, holes, etc.) the system automatically and transparently performs simple Boolean operations; this applies to all software using a type of “solid” catia modeling included.
in more caia allows you to undertake several roads i.e., or create “emptyings” directly in the “partbody” or create new “body” and to add or subtract them later to other “body” or “partbody”.
the fact of using different modes is at your discretion.
I finally answer your last statement by designing molds.
if I have in the library for example a guide column with its respective “cutting tool” or “sede” I simply have in the 2 body file. in the mold I will put the column but in the mold I will remove the seat using the commands of the “boolean” operations. I don't think I model like 15 years ago; 15 years ago he modeled only figure and out-figure; the rest was all 2d.
Good things cumpà.

in my opinion the choice of how to proceed for the creation of a particular depends exclusively on the person, there is no right method and a wrong one.
personally for particular complexes I use Boolean to simplify my life.

It seems to me that you answered and contradicted yourself .... it is useless if you make a simple piece and it is useful if you make it complex............ Right!
I often use holes and pockets on different leotards and then in the end with boolean I do the subtraction from the main body (it is also + easy to see holes intersections).
cmq if you use separate catia leotards it puts us less to recalculate the part in case of changes and then updates......... If you make a lot of holes in a piece without boolean and then change something becomes "sick" .........:biggrin:

I'm not saying that the system doesn't work with boolean, but sure to make a hole, I don't put on it. I do: I create a cylinder and subtract it?

Of course, everyone does as they want and it is true that there are more roads to get to the usual point, you must also see the time that one puts us.

Why?
we are simply saying the same thing:
to make a hole or pockets with simple geometry (as he said oua of his colleague) it is useless to use boolean
for particular parts and uses can be useful.
I do not see the reason for all this infertration sincerely, opua asked a precise question and I answered him then it is clear that the individual case should be evaluated.

hello to all:finger:

 

[mcbramby]

Calm down. Calm down.

no one wants to make professors or go against someone............ .

I just wanted to say that if you want you can use holes and pockets even with boolean and if you have pieces with many holes it is a good strategy.................. :finger:

cmq we have understood, each does as you want:bekle:

[Inguz]

I interfere. . .

I think mcbramby used the correct word: "strategy" each of us builds its own model first in the head and then in the modeler, then the strategy that everyone decides to adopt to create mathematics depends on how much they want to make the object changeable. I personally use the boleanes never because I find that they weigh the structure of the model a lot. It's always a question of approach and method. .

 

[falonef]

I think the Boolean should be used on the basis of precise criteria:
- How will my catpart be made?
- What process do I have to respect?
- Is there a methodology of childbirth realization?
- etc.

a hole can be created both with the hole and boolean function.
use boolean so much to change the type of modeling or to avoid simple modifications does not make much sense! ! !

 

[Plus ENGINEERING]

...using the boolean so much to change the type of modeling or to avoid simple changes does not make much sense! ! !

I agree! In my opinion, boolean should only be used in particular cases. for example when you do not succeed in any other way to limit a pocket or prisma; or when you build a set of elements to repeat several times in the piece. for the latter case, it is convenient to create this set of elements in a body, repeat the body n times (matrix, copy, etc.), and then docked the boolean to limit everything. if in this set of elements there is a hole to change, for example, it becomes very easy to do it because it changes once only in the body created. you may also not resort to boolean by performing the matrix n times for each element of the assemblies of elements to be created. This system would obviously be much more complex.

Hello everyone
I have a problem with Boolean operations.
I have the need, for complexity of geometry, to perform a workmanship on a piece by adding two parts-body, assembling them and then subtracting them to the part-body.
during this last operation a message appears to me:
"the user is trying to create a boolean operation between an ordered body (ogs or body) and an unordered body (gs or solid body). the body operating will not be moved to the Boolean feature".
if I decide to proceed, the operation is performed, but the secondary body does not go into the feature (in partbody). what is this due to? and above all, how can I solve?
thanks to all

Hi.

in tools\options\infrastructure in the table "part document", you must remove the check on "hybrid modeling".

probably at the opening of the file the color of the gear of the part body was gray, this signals the not alignment with the systemwhich instead is in iblida mode (ogs or ordered).

Setting change should make the body's gear green, indicating that the system is aligned with the file.

It's something that happens in the ug.
the separate leotards make sure that the recalculator only goes on the features that make up the body in edit and on the boolean between the body.
with very large models the difference you feel, here is if you feel...

Thank you
I'll try to change the settings. The color was gray and it smelled me, but I didn't know how to fix it.
I'll update you. . .

Hello, everyone.
I have been working for about 5 years with catia v5 and I can tell you that the vast majority of plastic pieces of large size (such as the aspiration boxes x example), must necessarily be made with the booleans, because otherwise the risk that the model is weeping for a radius that changes or for a hole that expands, is very high.
Boolean instead, being features built separately and assembled allow a more immediate understanding of the model and, above all, a very reduced time for changes.

 

[Sbilf]

Hello everyone,
I welcome this discussion not to open another discussion, (maybe for a few steps)

I need to change the polarity of a body, that is, using the possibility of drilling with the drillhole I have to make a body that inside has a "copy as result with link" of the partbody.
This body called drillhole must be negative.

I don't remember how polarity changes in bodies
thanks to all
