mathematical import from other software

[Biagio57]

Hello everyone
I bring to your attention, and I hope to have answer, the problem of importing solids from other software, is for me indispensable to know how to make recognize the imported mathematicians to perform all the processing of assembly, remove and rework, typical and indispensable operations for the design of sheet metal molds.
I have tried in every way but I can't use what is normally provided by the customer, say that they are in a dead end does not make the idea, say that I can't work this way is the pure reality.

 

[peloritano]

you work, you work.... armed with so much patience... We use the same software... we are in the same field... we have the same problems...
The advice I can give you is to try to learn as much as possible caia because it makes you available so many but many tools to overcome the most varied problems. ...
Unfortunately, I don't think it's possible to solve this in any way and it's also common to other software.

I do it very short, also because given the data of the problem you provide (pochini), I can only make a general speech.
normally a cad3d can read interchange formats (iges and step for example), if not even native files of other cad.
what you have to do is verify that formats reads the progamma you use, you and ask who gives you the matamaticians to send them to one of them.

Bye.

thanks to both for having responded, but I expected clarification.
I will try to be clearer, when it is possible of course I send the file to the catia format, but often it happens that other formats I receive are igs or step, in these last cases, as I do to use the files, generally it is a thick sheet, I don't think that you or others you put to build next piece, it is crazy, also seen the complexity of the shapes.
considered that it is indispensable to use these geometries for the realization of the various figures of the mold.
with visi (of the truth) I have no problem in manipulating any type of files and using it for the various forms.
boys an effort, maybe I mistake something, I attach an igs file to better understand, considering that all the forms you will see must be used several times, both in the lower and upper part.

I repeat that catia makes available all the tools to work. . .
in this case they provided you the math element with thickness... .

I don't understand your way of working.... I'll explain better.. .

Having the math in question first of all I choose the side on which to work (actually your customers should have provided a math without thickness saying whether it is the matrix side or the sting side, they should also provide you with numerous other information including the process cad).
However the skin on one side you can extract it with the command that is found in the workbench shape design.... In this way you have a math without thickness (but you know which side it is) on which you can easily work... Once you do all the operations you want you to go to machine tools.... here catia offers other tools to work. In particular, there is the offset value that allows you to reintroduce the sheet thickness, in fact the thing that I don't understand is because you say you have to work on both sides. Just work on one side only since the other side only differs from the sheet thickness. . .
Note that once you have the skin on which you can work quietly it is possible at any time to return to a thick sheet using the tools that catia puts you at your disposal

Hi, I looked at the iges and I miss a couple of surfaces.
from what I know the import of iges in nx is not the best for which it could be such a problem.
I tell you briefly my experience of exporting step from nx to a molder working with catia.
we couldn't figure out why he couldn't properly import the solid (and then run the cam) that was perfect for me.
I came up with the idea of putting the export tolerance to 0.0001 mm. a pretty heavy but manageable file from catia came.
test that modelling tolerances are used by other cads and which are exported.
Good job.

I know him. we have made prototypes some time ago!:wink:
in any case, apart from some defects of missing surfaces, the reality is that with conversion to iges the solid is lost! in fact if you look in the tree of catia
all surfaces are placed in a separate geometric group.
in the options of catia isges,to tell the truth there would be a sectage to tell him to join everything during the import... but I personally prefer to handle this if you need it.
Usually, as a result of several tests carried out along with my supplier using nx, I use conversions in step, so I always have a solid (even if fired) and 99% of the times I get well.
or lately I have seen that also the direct conversion nx-v5 carried out with the default converter of nx, it works quite well...except some rare case in which it is stacked.
at the end, when you have the solid element in catia v5, proceed as you prefer by using the numerous tools that v5 puts you at your disposal, following for example the scheme that rightly suggested you hairy... which then eventually is also what I use.

Hi.
I attached you a catpart file of your object, ready to be used.
is a solid, clearly not parametric.
I don't understand the difficulties you had in making it solid. I think you might miss the basics to do it. Surely you are self-taught and in this case it is difficult to explain how I could make the solid in less than a minute.
I still hope I helped you.
Hi.

thanks to all for the help
premise, working in the sheet metal mold industry for 38 years, I agree that you can work with the skin or with the thick solid, is what I have always done, as you have no problem designing, but with faces.
I have just started with catia, in order to be able to work with those who only use this system, I confirm to victorious that I thank for sending the file (I can not read it, currently I use the r14 waiting for the definitive passage to r21, if you can send it back!) that are for the use of this cad a beginner, even if I start to move with discreet autonomy.
I come to the current problem, I am taking advantage of the month of August to carry out with the knowledge of catia, I am beginning to work with the use of pieces that I have in archive (I made some of these estimates and design) to perform all those construction operations of the various steps of sheet forming, but I am encapsulated in the problem that I have placed to your attention; I can't in any way use what amount, not even the skin I extract correctly, I can't use it in the various processes of "remove" etc and I haven't yet understood why.
I will, if necessary, try with the victorious file (if you have the patience to send it back to me as I asked, and if not it is too disturbed to write me the blessed procedure) in the meantime I am still.

Hi.
I understand your despair and want to help you.
it becomes impossible to explain with images and text files the procedure.
if you leave me your home or office fixed phone number and send it to this arc_32 email address[chiocciola]hotmail.com . specifying the time I can call you... We're both in front of the video and trying to drive you to solve your problem

good victorious:finger:
find people so kind and helpful.
you have earned 1000 points:biggrin: this is the spirit of the forum... maximum.

for quick help, I hope you have help, try to view the two files I send you.
I've made volume of your juices with some holes.
in sequence I used the following gsd commands:

join
compositions
Fill
join

once I created the global superfice I used "close a superfice in partdesign.

at this point, in the image then see the function used to remove the processing.
this function was already present from the r13.

Hi.

ps. the curious thing however is that you ask for the importation of mathematicians from other cads but your iges comes from a r14. mystery:

 

[Biagio57]

I thank officially victorious because this goes beyond the spirit of the forum this is the help that I hope in the future to be able to return, for this I do not give you points would not be enough but consider me available for what I can.
I contact:smile::smile::smile:

 

[Biagio57]

thanks ferrezio also for your availability, I will try in the meantime to follow what you say, regarding the mystery of the file, there is no mystery, it is an igs file made with catia previously imported, one of the many tests, I could send you an igs file made with visi or provided by the client or prt, in essence there is no mysteries but only confusion.

 

[ferrezio]

if I had sent the actual starting iges the sequence would have been more truthful, since normally in the iges I go to check the emission tolerances of the file, so the result in import could be very different as it also pointed out baskets.

Having done the r14 iges has lost information and the surfaces could have been lost during the initial converction phase.

Hi.

 

[stef_design]

since normally in iges I go to check the file emission tolerances

hi ferrezio, in caia as you can verify the tolerance of emission of a math.
What command do you use?
Thank you:

 

[ferrezio]

just open the iges with a text editor.

By analyzing geometries, you can change iges import parameters.

Hi.

Goddamn opening an iges with the known block I'd never heard of her... but what I opened is less ordered than your... where can you have information about what all those numbers and codes mean?? ?

 

[ferrezio]

If it wasn't so, it wouldn't be an interchange format, but it would be a propretarian standard.
http://it.wikipedia.org/wiki/igesFrom here you can understand the structure of an iges, there are also links to trace back to the reception of the national institute of standards and technology.

Hi.

 

[ceschi1959]

I never heard of it.

even the dxf!!:smile:
