Good morning to all

someone who is currently applying mbd technique with creo?
I would like to exchange some info about creating/management of annotations on 3d models.
 
Does anyone have or is it going to leave the tables in favor of the quotation of model 3d?
 
Some companies are working in that direction but, if I allow myself, your question is very vague. What would you do?
 
I would like to understand the impact that would have this methodology on the technical office .
the creation of the tables for the insertion of the annotations
in model 3d; in practice quotas, tolerances and roughness would be inserted directly on model 3d .

hi, I quote in 3d for simplicity; I insert tolerances or annotations. I do it to simplify my work later when the production boards are needed. at the moment 3d annotations do not replace the tables because in production they still serve. However, it speeds up the execution because as soon as you whip the view you already have the odds and annotations turned on.

perfect... but do you insert annotations or "light" the odds you used in the creation of features?
 
at the corporate level, the abandonment of 2d drawings is very broad as an argument, not all entities are able to abandon the diesgnities (see for example acceptance materials, quality, testing etc.); Each body should be equipped with computers/tablets linked to a single database managed (pdm), with adequate size monitors (so space required) and especially protected adequately (which is not always easy).
in a company where I worked, the paper was reduced internally to 5-10% of the total (standard industrial machines), but the external suppliers, however, required drawing 2d.

both things... if I have the features I turn on the modeling quotas first. If it's not enough, I'll have to add new ones that will have a [bleep] word.
not always are available modeling quotas because you may have imported geometries, external copy geometry etc... in this case if you already know that you will not have to change the piece does not make sense to remake the modeling from scratch. so for me it is faster to quote in 3d geometry.

but if I give you a 3d for example in step242 format with all semantic information related to surface tolerances and roughness... why do you need the table?
I understand the habit even cultural if you want ..and maybe not all have work centers able to read 3d objects

great here I wanted to arrive ... if I already listed the features (not the imported ones) I do not add annotation feature that would be a "duplicate" of the quotas inserted in the sketch ...
 
for my modest opinion you must first question how to see the work of annotations you are doing. if in the company you have windchill it simplifies because any company can see the 3d with creo view having also the advanced management of accesses. if you have to share with suppliers who do not have access to a pdm system and in addition are "stops" to 2d boards the thing gets complicated not little. a ns customer has proposed to their client to create documentation only in 3d paventadogli a cost saving and a greater ease of research.

It is not a cultural issue, but because of the simple fact that design, construction and verification quotas, rarely coincide, on the 3d add them all can be heavy, also there is extra information (sealing pairs, operating instructions, special tools to use etc.) that on a 2d find plenty of space, on the 3d much less and this even if then the 2d view it and just without printing it.

the 242 at the moment is reserved practically to the only mechanical processing, but the needs of a 2d table go well beyond this compartment.

even the world of sheet metals still have different needs, quotating a development has become anachronistic (just that it changes the bending machine with specific knives and prisms and already the development on the 2d is not useful), but the dimensions of encumbrance, are faster to display on a 2d for those who have to store it, paint it, treat it, handle it.
 
the "problem" is that a mechanical design has developed over the decades to be a rare example of compactness and completeness difficult to beat. for this I would recommend, for now, to use the 3d annotations only in the drawings that have few information, so I would exclude construction drawings and focus on the drawings use and maintenance, assembly or other.

what is present on the 2d cannot be reported on a 3d? having in the company also windchill in practice all that is not graphic is thrown into the wtpart (various notes,material,treatments ..)
What I'm struggling to prove is:
There is a real saving of time not having to create table 2d but inserting all the notes on the 3d?
Would suppliers give pvz as consultation and step242 to feed cn ...? ?
 
saving time is definitely because there would be no more drw to create, so manage, store etc... But today it would be minimal if we compared it with the lack that there would be no more to have them.
However, I imagine it a day when in a company the manager stood up from the bed and said from today we don't draw anymore! We do that we work without paper, only with tablets and files. a revolution dictated by an unprecedented radical choice. Let's just stop smoking. . .
Cool:

Good morning calacc is just what!! Enough paper, but already we turn little, but above all it is enough 2d!
 
Good morning to all
I'm going back to the initial question. Is it really the future?
We temporarily neglect the cultural factor, it is clear that it is a remarkable "salt" for all entities interested in the production flow from the technical office but also those who have to build the object, who test it who does the cycle ec ...
