And here you hurt... because there are not only surfaces and complex modeling (where a hirange is a must) but there is also a mixed carpentry mechanic that all cads know how to do, but where someone is much faster than others. I see in solidworks a much more performing tool in the sense that it takes half the time compared to proe. I stopped at the wf4, then I abandoned him, I got the license there stopped and not updated and point.
I eventually sell a lot of "paper" and use the tool that makes me produce it before, which is more flexible during modeling to quickly implement changes, etc....
in proe I found many obstacles, radiable if you want, but with great waste of time that then the client is ready to recognize you. . The images of the_matrix, in my opinion and I agree that this is not just a commercial problem. . .

You're not able to do this... guaranteed. (apart from what "carrozzeria" means... Do you mean the outdoors or the white body?
doing a body shop doesn't mean that, to mean: https://www.youtube.com/watch?v=ssh0zcum_kior this https://www.youtube.com/watch?v=b85oe1ztduy
o questo: https://www.youtube.com/watch?v=h50cvuysvra These are jokes or exercises that show functionality using as an excuse a car, but they could use a mouse or a coffee machine... it would be better... and this is true for all those who throw themselves in these reconstructions. . serve to make a kind of style mockup and make "a species" of outside.. .
But if you put yourself on this plane, I guarantee that rhino and alias go triple in speed.
Also because now, to make these "mockups" designers tend to use subd surfing.
then when you do the real style use different techniques and you have to get different results that only modelers like alias, catia, icem and nx manage to get.
but here we go on a quite complex speech of surface quality and what this "quality" means, which probably affects a few.

I'm telling you... I, for example, assure you that as a modeler, assembly and table, with nx I am not able to compete with swx and even, I think, with if. if there are no other judgement factors (cae, cam, mechatronica, plm, documentation, electric and mechanical routing, extreme large assembly, pcb, etc) on pure mechanics, the ease of use and immediacy of solidx are absolutely unbeatable (for me and nx, I mean).

How come automotive surfaces have this demand for extreme precision?
to me pass various sheet metals made with catia or other high-end systems, I open them with inventor or rhino to use them as reference for my machines, what do I miss as information?

Really, even as a modeler?
I'd like to have a movie with subdivision modeling nx:https://www.youtube.com/watch?v=d9ofbpjar1qeven with rhino you can, but nx to see it so appears more immediate.
swx and what do they say?

Don't lose anything. today the nurbs surfaces are the industrial standard in the cagd and constitute the mathematical sources for all modern geometric modeling kernels. until cads communicate through files that share the same maths, there should be no loss of information (other than the errors of interpretation that are visible and do not compromise the information on geometry).
with rhino I also draw optical surfaces, which are often much more demanding than the surfaces called "in class a" of the automotive industry. I often interact with other cads (also with inventor), and sometimes I happen to have some badly built files, but eventually it fixes everything.

I see that you have rhino and alias, like me, only that I alias have it together with the inventor's suite and I have never faced it.
My inventor's salesman says I could have avoided buying rhino, because with alias I would have done the same thing, right?
I use it at a very low level and I don't need it if not to manipulate surfaces made by others.

mmmmm, didn't you see solid edge?
I am a good solid edge utonto since 2000, I used for about a year both inventor and solidworks, and I continue to prefer solid edge.
cmq all those who have started with a cad will tell you that they are well with that.....
make a demo and not discard it a priori, which has excellent potential.

I think you don't know what you're talking about.
before you know what I can do... you're gonna have to do 40 laps and you're still not getting it.
I'll stop here for decency.

Obviously I was referring to the information of geometry, because it is clear that you lose the tree of the history of the construction of the model.
Yeah, he's right. But try to take the time to learn how to do with alias what you do with rhino, and then you will tell us if you go to be part of those who think faster and immediate the use of rhino or if instead you will find yourself among those who support the opposite.

quoto.What's going on? They don't give you any more food and you're inactive?
why don't you make a constructive discussion by pointing out what the various definitions of surfaces, classes, etc. mean?
could be interesting, and from there you could compare better the various cad systems.

No, of course not as a surface modeler. . .
I meant as a cad for mechanics and carpentry.
that video refers to an old version of nx..
now the realized shape is much more evolved: https://www.youtube.com/watch?v=8xtgqycnnpkhttps://www.youtube.com/watch?v=zlack_uwqp4

the problematic of the outside classes is related to the fact that a minimal inaccuracy or evil trend generates flexes and a non-perfect appearance on the physical model.
Now: what makes a surface modeler "good or not good" for classes a? 3/4 things
1) the presence of specific features (non-proportional nitrogen, g3 continuity and g4 on curves and surfaces, perfect functionality of creating both direct and indirect surfaces)
2) reliability in the creation of the surfaces themselves (if for example in data cases a surface is created with a set of cubes or quintics instead of a class 6 bezier rectory, is an unacceptable result from a stylist)
3) reliability in regeneration. in the case of adoption of parametric approach (only nx and catia can... icem and alias no or are very limited) it is necessary that the quality of the curves and surfaces that you have at the time of creation is preserved in the regeneration always and anyway (something but simple. . )
4) powerful surface analysis tools that make capiure in real time the quality of the surfaces themselves (perfect shading, zebra, comb sections etc)
You never have a problem because you use the superians only as a reference... the surface itself is milled to make the mold, with other tools. :finger:
