signed in the cartilage

[Fabio24]

Good morning to all

a curiosity as a result of various opinions within the technical offices in which I worked, according to you who design a particular or however who does the model 3d is also the one who must fill with his name the signature in the cart. because often we happen that those who make the 3d are not the same person who puts the particular on the table, so if the designer makes a mistake in the table it is right that answer who modeled it instead? how do you manage this aspect in the companies you work in? Thank you.

could also be worth the reverse speech: If the 3d model is wrong, why should the designer answer that put his name on the table?
In my opinion, those who model the 3d are responsible for the project, therefore also tables, which should be checked and validated before release.

 

[MassiVonWeizen]

in my opinion who model the 3d is responsible for the project,

I wouldn't say. if to me dependent designer is given to make the model of a chariot whose calculations were made by another person and the subsequent drawing from another still should I answer the project that maybe previews other tens of details? It seems frankly absurd! not necessarily who model has the ability to evaluate the work of the designer.

therefore also tables, which should be checked and validated before release.

on the cartiglio in addition to the voice "designed by" there are the voices "controlled by" and "approved by" that are the steps after drawing; the final figure "controlled by" is the one that answers any errors. which then these 2 steps no longer carry out is another pair of sleeves.
Perhaps it would be the case to add the item "modeled by" to this point

Unfortunately neither of them, but in today's state it is the modeler 3d that has the name. Unfortunately it has been eliminated in many places the '' controlled by' because many people do not want responsibility but only the resulting salary.

to me modeler give to make an element in which the bearings are inserted of which I know the size and I do the suitable seats, but who decides whether the bearing will be mounted to interference or with game, if you need a grinding or just a turning, that decides the designer.
I can shape a 20 meter long frame, but I am not required to know whether it can be welded intermittently or completely, if the angle welds are enough and if and where the penetration welds are needed.

I agree in full. at the end a piece can be practically to be thrown because of a wrong tolerance put by the designer, while perhaps the one who shaped him thought otherwise.... to me personally happened several times this case.

who performs the 3d model, in most cases, is the designer himself and as such should put on the 3d the indications of the type of welding, this to remove any doubt and responsibility to those who will perform the 2d.
to my parer, where it is possible, who model the 3d should himself perform the 2d.
I personally noticed that, so doing, many design errors are filtered out and eliminated and responsibility is unequivocal.
often those who perform the 2d on a 3d model made by others, want for inexperience, want for poor sense of collaboration, perform as automaton

I am not so much in agreement, from my experience the designer, as I am not, does the modeling of maximum (or even only the 2d layout) without entering into detail (e.g. fixing holes, structural stiffness, etc.) but giving indications with simple notes. the modeler will then complete everything making it feasible. the designer in turn will make the functional executive tables.
if the designer has to model and then draw everything to bring out a project of dozens of details (excluding pernetti and washers) puts us a month in which he does not devote himself to anything else.

generally for me it is so, but there are also cases of external offices that do only one of the steps then or the model or table; at the beginning of my drawing board I was in this situation and finished the plan boards (which were from 3d or less) sent to the client who controlled them and eventually sent them back for the corrections of the case. the responsibility of the error was of course mine, but of the conformity of the project not as controlled and validated by the customer.

I'm not your opinion. the responsibility of the designer is also in the size/structural stiffness including fixing points and their size.
if you know perfectly the skills of your employees then a free hand sketch is enough.

if the designer has to model and then draw everything to bring out a project of dozens of details (excluding pernetti and washers) puts us a month in which he does not devote himself to anything else.

for this I specified, "where possible"
