surface quality

between the surfaces making the zebras move you should see constant "beams":http://www.screencast.com/t/fo7cgmsf

Hey, what do you mean, "Fasce"? ?

Hey, what do you mean, "Fasce"? ?

refers to zebra strips, typically you have three cases:

1) between a surface and an adjacent stripes are discontinuous (i.e. steps from white to black): means that the two surfaces are connected to live edge.

2) between a surface and an adjacent one see an sudden variation of slope of the strips: means that the two surfaces are in continuous c1 (i.e. a connection between a plane and a cylinder or between two cylinders, typically the case of the constant beam connection)

3) between a surface and the adjacent strips are gently collected: means that the two surfaces are in continuous c2 (i.e. parabolic functions). Typically, stylose designs use c2 continuity, but I don't know if this has anything to do with the aerodynamic functionality of an object.

I was wondering about the importance of the constant rope connection, which has nothing to do with the curvature continuity.

p.s. better explain: the zebra strips I used them once I modeled cams. cams for fast mechanisms should be created based on grade 5 polynomial functions, and then I needed to check if the rolling track obtained was uniformly continuous. I keep saying I don't understand anything about design.

How come you say you don't know anything while here You let me to talk about it as an expert?

I believe that the exchange of views is legible, while the choice of certain verbal forms leaves a lot to be desired.
When they are aimed at hunters, steps, given its enviable pacacity, but I want to point out that using certain terms with some people exposes users, moderators, post, threads, as well as the whole forum to an escalation of insults, warnings, bans, and especially bitter blood.
I wonder, is it worth it?

No, it's not worth it.
I think I clarified in mp with a hunter. I don't want catia users and interested people to use their space improperly.

I hope for you too!

Forgiving, this is to be constructive, good and now let's go back to topic:-d
but can no one share training material on the most complex we call surfaces?
greetings and thanks to all.

 

[RS4]

Since you are very competent, would you also be generous with the community in explaining how aeronautical surfaces should be made (see that my not only wings those mails) and how to analyze them?

Thank you.

Waiting for rs4 lumens I place some image that can help you explain to me, if you can please, how to interpret the goodness of the surface made and where/as possibly I could correct/improvide.

Hey, baby. .

I've been trying to give you as much news as possible. .
the thing and complex there is a preliminary study of surfaces called master

Hi.

♪

 

[panormus]

thank you rs4, pndo from your keyboard :biggrin:

 

[panormus]

always waiting for rs4.. What do you say now? is the surface good?

 

[panormus]

But for love of the truth there is an area that doesn't drive me crazy, but that from zebraic analysis you won't see it... you will understand it yourself.

 

[panormus]

What? Where would you see?

 

[panormus]

What do you think now?
would you use it as a surface to work on? to be used for a mold for example? would come out for how it looks?

 

[panormus]

it seems necessary to publish the progress after breaking the boxes on sweeps, surfaces, fittings and various dryings.. .

I ask the surface experts and moulds to tell me what they think constructively:finger:

Good Sunday

 

[panormus]

and the other for a more accurate judgment.

 

[panormus]

and this is the complete model. I'm finally done!! :finger:

Am I done?

No! Now the interesting work begins. . .

If by chance, but I say by chance, some aeromodellist, maybe even aerospace, wants to give me suggestions step by step, do not intimidate.. :wink:

 

[falonef]

What's the point of a survey until 2014? ? ?

 

[panormus]

because in the long term I can understand how many experts in this area are there. many may be competent but write two messages a year.

How about my design?
