You might have read this. For those who haven't, the article has quite some nice pictures.

Well, to make those cartoonish looking cars, rhino is about fine !

But to make real cars....Is just useless. Nice to start learning 3D....But it cant even do decent surfaces.

When it comes to car modelling, for the design stage, StudioTools (autostudio) is the tool!

[Snecx]

I'm sure it's easy to say something like that but do you have any examples of "decent" surfaces that Rhino can't handle?

I do know a number of real cars that have been designed in Rhino, without StudioTools.

I know that Saleen S7 and Nike ONE designed in Rhino. Which are others?

Another one would be Lexus concept car for the movie, Minority Report.

well let´s discuss it over again
rhino isn´t bad and a lot of designers use it, so you can´t say rhino is a bad programm. it has it´s advantages (eg the price)
but in most of the cases the big manufacturers will rebuild those rhino "designmodels" in the app of their choice to get it into production.
at least that´s what i have experienced.

hey TwoOneOne,
Are they rebuilding cars those modeled in Alias Studio Tools? I know that most of big car manufacturers are using Catia. I heard that Catia's surface tolerance is 0.001. If i model a car has tolerance of 0.001 in Rhino, can i take it into catia and make BiW design of it in quality as A class?

I do know that Audi uses ST for design and Catia for the engineering part. but i´m not sure how ST is integrated in their workflow and if they actually use ST models in Catia.

I heard that Catia's surface tolerance is 0.001. If i model a car has tolerance of 0.001 in Rhino, can i take it into catia and make BiW design of it in quality as A class?

not sure about this one. that´s something you´ll have to try.

Rhino can produce Class A surfaces just the same as StudioTools. So far Rhino lacks few features but I'm sure Rhino4 has these implemented.

I'm just interested on the technical part on what "decent" surfaces Rhino can't do that StudioTools can. That is what most people claim in the first place whenever Rhino is mentioned.

Anyway, at this point I believe that mechatronz has no real facts to support the point he said about how Rhino is unable to produce decent surfaces.

You are wrong......Google it, and learn !
Rhino hasnt even got, real surface checking tools !

Dont compare a mini with a ferrari dude !
I m not gonna be lecturing here on how crap rhino is.....Go google. Is all there.

Regards !

You said Rhino is useless when it comes to cars. Yet we have some examples of real cars designed entirely in Rhino. Phil Frank uses Rhino for his work, I don't see how it is useless.

[...] Nice to start learning 3D....But it cant even do decent surfaces. [...]

You said Rhino can't even make decent surfaces. Rhino can handle NURBS surfacing as well as StudioTools. We have seen Class A surfacing with Rhino. Rhino supports curve degree up to 11. StudioTools has up to 7, with additional curve degrees available only with extra charges. In short, Rhino and StudioTools are almost equal in terms of NURBS handling.

What is wrong? I am merely asking why you say it is useless and can't produce decent surfaces. You did not provide answer but merely diverting to other feature items to differentiate Rhino and StudioTools more. What's the point?

I hope you do get me right I am not comparing features of both program. In terms of car modelling and evaluation, StudioTools is much better. It has bloat-load of features but in terms of NURBS handling, Rhino is not far from it. In fact I don't see how it is worse in that aspect.

You said it is useless and can't produce decent surfaces. I merely asked why it is useless and what "decent" surfaces it can't produce, because I don't think it is true and I provided examples to support my points. You did not answer. Then you simply said I am wrong.

Later you said I am comparing both and needs Google.

Seriously...?

mechatronz ?? dont compare a Mini to a Ferrari ?? I am working with Mini Cad Data, and i dont see a big difference between a Mini and a Ferrari engineering-wise...
