It is a shame to have seen this discussion only now. . .
the topic is very interesting and certainly puncture of ideas of interest.
I attach some documents that can help you understand the mbe theme (model based enterprise - this is the real name).http://model-based-enterprise.org/index.htmlfirst of all this is the link to the association mbe which is an authority in this regard.
the problem of the bee is never nbell'engineering... putting pmes in place of creating a table is all summed up a nice saving of time.
The only real problem is that, together with the pmi, the way of quotating would be radically changed... the "constructive" designs should obviously be eliminated... but do you think there is someone who builds a model based on a 2d design?
in the annotated models it is necessary to put only the quotas and the tolerances that will then be checked. . . all the rest should be made to aprtire from model 3d.
the problem comes downstream:
- manufacturing... is the mfg department able to directly use a mbe model? therefore, the cam tools are able to discern between a hole d(and a hole d8h7? one will be worked with nuna simple drilling... The other must be argued. it is necessary that the cams act independently.. .
and then we are now entering the additive manufacturing era... 2d? ? ?
- quality'. who controls the model has a great advantage from the adoption of the... no way... if a cmm is evolved and integrated with the cad, it can create in a semi-automatic way (style cam) the path of control going to make leverage of the pmi of the 3d mbe.
- suppliers... suppliers must equip themselves with tools that can easily read a model mbe. step is a way... we normally propose the jt. nx format is also able to read a jt format generated by another cad and transform the pmi directions into real pmi.
In general, however, what they say, suppliers work better on 3d data than 2d.
And then, let's just say... is also a question of natural selection: Don't you want to evolve? patience... change of supplier... a little like 30 years ago when you passed from the tecnigraph to the cad
- legal... as 2d drawings have legal value, you are able to store them with a ltdr logic (long term date retrieval). .. is something to evaluate... 2ds are turned into tiff or pdf for example... 3D? How can you be sure that in 30 years your noted 3d is legible?
- documentation... who does the product documentation is ready to receive the 3d instead of the 2d? often, without saying, the 3d are made (in fact, remade!). there are now very efficient documentation software (cortona 3d for example) that allow direct use of 3d... and if you do not want to go too far, jts can be placed directly in office files (word, powerpoint, excel, etc). therefore for these people the 3d mbe is manna from heaven.
- acquired... purchases must send around no more tables but 3d. Is there a problem? I don't think so.
other considerations.
- 3D consultation. It is normal that a 3d is used to discuss while developing the product. Of course a nice piece of paper is better... question: is it impossible to have a "2d" of a 3d mbe? No!! indeed... it is desirable. . Normally cads (at least nx...) can sharply print you a "2d" loot to use for discussions... I often carry the example of emails. emails replaced paper communications, right? who of us still uses fax, letters etc.? Nobody.
you print the email to bring it into a discussion? Yeah, it's easier to pop a piece of paper... And what do you do with the paper that you've been sloppy about after the meeting? How do you throw it in the trash? Right, it's just that time to discuss.
Well, like a 3d mbe... print the view model (and it is similar to a 2d) ... discuss it and then that "2d" as well as a printed email throw it away.
ability of designers. designers have to change their heads... together with the mbe you normally do a nice asme quotation course because we all have a little forgotten the quotation rules and tolerances. quotating asmes, then quotating only the size that will then be controlled by quality is a mandatory and natural way.
cultural change. from previous considerations it is clear that the great obstacle lies in the head of people who have to change culture. who of you has my age remembers the betting during passage 2d > 3d... here, the bee is this... a battle to get people to think differently.
mbe of components/assembly. when you start a project mbe (and I have already followed and completed 3... the first in 2008, when nx and teamcenter really did a hard work) the first thing to understand is whether you can delete the 2d completely or by stages.. .
2d of components
2d of groups
2d mounting
Where do you start?
I think you can do everything at once if the company decides... but at least 2d assembly and groups can be done effortlessly.
Good job.. .
