surface quality

[marcof]

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

View attachment 33218[/QUOTE]I believe that the above experts would be able to help you much more easily if you placed the steps. from the only images you understand something, but only in case of macroscopic problems, such as in the lower part of the vertical entanglement where the surface has strange curvatures that should not be there.
If I'm not mistaken, you're not interested in matching your model with the blueprints and the real aircraft but only the quality of the real surfaces?

 

[panormus]

That part I could correct now that it is a solid, in part design, with a proper pocket.

I think it's a bad idea to change solids from wrong surfaces. so much it is worth putting in place the starting surfaces.confirm that you only care about the quality of the surfaces and not the fidelity with the blueprints and the forms of the real aircraft?

 

[panormus]

I only care:
draw well aircraft in scale,
to choose the best construction solution,
analyze the loads and capabilities of the structure,
know how to design and build the control mechanisms and simulate the movement,
draw a beautiful livery,
build the blades for scale realization,
to put everything in the plant in a clear way and to allow its understanding,
distribute the project,
build the aircraft,
know how to make the molds,
know how to weld the beam,
to paint metal, wood and composites,
. and something else.
Can you help me with something?

fantastic that "only"...
starting from the first point of the ambitious list, I would say that you intend to make aircraft that reproduce the appearances of the original aircraft.
great, but from this point of view I would say that in your model the back of the fuselage in which the vertical rudder is inserted does not have the correct form (but I had already made the same observations in another thread). judging by images, even the development of the vertical rudder surface is not correct.

that just wanted to be a joke.. :wink:

Hey marcof, for 2000 euri I'm gonna spin the step file with the tail corrections...

Hey marcof, for 2000 euri I'm gonna spin the step file with the tail corrections...

naa...2000€ for that step are too few, I think of Chinese with rats larger than the holes:smile:.
the value of that tail surface or the entire aircraft made as a rule of art is worth much more. If I had talked about 20,000 euros I could have thought of a job well done, but buying it at 2000€ is like buying the camera in a service area "caused from the truck", to 500€ instead of 5,000. then tap on a brick;-)
Still quiet, I don't need the step, and I don't even need the native files in the cat.
the native files would instead serve those who could look at how you did those surfaces and then give you the help you ask. you know, looking at images with zebra stripes discontinuous or curled (which are on step or screenshot) is only useful to say "here is not good, here is not, here is enough, here is yes, etc." but you, in this way, of why the result came to you so (timon and terminal part of the fuselage are wrong) you know as before.

Marcof friendship, friendship: where do you put it? you have considered everything without thinking that you can sell for friendship :tongue:
So you don't buy it? :frown:
and I who had already spent them in my head for a professional cat course... and I made the flash "adesso marcof can no longer tell me anything.... ":biggrin:

Well it is not that as a forum this catia is very popular and rich of experienced people ready to share.
I don't hurt so many people in the forum who helped me a lot and thank you very much, with someone there is also a nice telematic friendship, but I think we are far from the tributaries for example of baronerosso.it (forum of aeromodellismo).

rather than telling me "you know how much before" because you don't contribute to my formation and growth without limiting yourself to saying only what's wrong, which is good for me and is good for me,... but you also need more to grow. . I also need to know "how" to reach my purpose that here in this trhead is "first to make a nice surface" and then the rest.

Can you give me a hand like that? I attach the file of the tail surface...

apart from finding a forum where you can talk about catia I think it is rather difficult, if it is not the official forum for registered users and that are in assistance. catia is not a program with which you normally fuck to have fun.
I went to see that forum you mention, and some of your posts... You've ripped them off.

ah, I also read that you also wrote that here on cad3d there was no one able to give you a hand with caia to solve your problems with surfaces etc...:frown:

apart from these details, that forum is good for advice on building aeromodels, but on cad I read some nuclear-powered michiate so you should stay here and settle for what passes the convent when experienced users on surfaces can help you.
There is then to say that, and I repeat to you, I have started with the wrong foot, claiming to learn how to use the surfaces by modeling a complex object like that object of this thread using one of the most sophisticated cads in circulation. in the sweep command options you lose us, and choose this option rather than that other means you know before what influence they will have on the surfaces you go to create. in the other thread I had made you the comparison between learning how to use the surfaces and pretending to learn how to fly on a su26 instead of on a p66 spacecraft. you wanted to go straight up on the su26 and imho you're crashing all the time. the porblem is that you do not want to hear it say and attack with complaints about the criticisms that you consider not constructive and blah blah blah blah.
You understand that it becomes difficult (and also uninteresting) to relate in this way, and it happens that it can come natural to leave you in your broth.

rather than tell me "you know as soon as possible"

My speech was a much more articulate speech (reread it), in relation to the fact that places of unnecessary images instead of the native casket files and then pretend that people catch you tell you what you're wrong. but what little do you want to say from a surface already made, if not that it is beautiful, discreet or ugly? Do you understand that who can help you can do it only by having your files available?. Come on, try not to abuse my patience by giving me phrases I didn't write because then I'm really embarrassed

because you don't contribute to my formation and growth without just saying what's wrong, which is good for me and is good for me, but you also need something to grow. . I also need to know "how" to reach my purpose that here in this trhead is "first to make a nice surface" and then the rest.

I can tell you that the forms you're doing are completely different from the blueprints. not only, I can tell you that to look at your images and in this case the iges file you posted the surfaces also have defects due to how you made them. and how did you make them? Bho!!! You know that only you and nobody can understand it from an iges file.

Can you give me a hand like that?

I'm handing it to you, explaining how you have to do it to help you get a hand from the cat. I don't use it. I had tried to give it to the other thread by pointing out the inconsistencies between the blueprints, the photos of the real plane and your model, but they are obviously not topics that interest you.

I attach the file of the tail surface...

the fuselage section is totally invented; Not even related to the su-26. despite this there are irregularities of the surface in the depth rudder area.
but the photos I posted from here onwardshttp://www.cad3d.it/forum1/showthre...una-superficie&p=295203&viewfull=1#post295203and the blueprints did you study them well? ?
the fuselage, from behind the cockpit to the tail, has the sides and the bottom almost flat while you have made almost an ellipse.
iho at least half fuselage is to be completely remade and the other half is to be settled. idem for vertical engagement. wings can't be said anything because... there are no files, but if you have swept a profile along some guide curve I doubt very much that there is correspondence with the centines and the actual profile of the wing.

Do you want me to tell you that this is all right?
If you want me to tell you, the 2000€ you have to give me

 

[panormus]

How would you do that? on exponents? from the tips on how, do not limit yourself to judging on... explains, do, post,.. it productives ahead.

I'm afraid you're too intent on pulling straight to your way to look around and seize the details of the landscape.. .

in this posthttp://www.cad3d.it/forum1/showthre...una-superficie&p=295203&viewfull=1#post295203and in the many subsequent posts as I would have done you I wrote and illustrated abundantly. others then gave you general suggestions on the use of surfaces.
use strategies that don't work as you want but stubbornly pretend that you tell yourself how to make them work. but if they do not work (and the reasons are many, mainly related to the inexperience on surface modeling) there is little to insist. or change strategy or you're aware of what comes out.
I give you a banal example: I have the sweep surface of only one profile through guide curves to generate wing profiles is, among all, perhaps the least suitable. I think it's better a loft between the sections of the pennies, sections that are known according to the alar profiles adopted.

is productive ahead.

This is so beautiful! What are you doing, "I'm even up"? look that the production on your model should be you, not me .
If you place the images of your work here and ask what you think you will have to do with a reason that you will receive reviews about what you see regardless of what you expect or want to hear.
for now you see a model different from the original and with several defects on the surfaces, surfaces that nobody except you know how they were generated, with which parameters, with which profiles and of what quality. You know well that, after months of work on your part, with the "finished" model and no native file on which to reason, for caia owners there is little to invent mraculous solutions.
I wish you luck and good work.

I would like to point out publicly that the debate closed by me was reopened by the supermoderator Sandra who considered it inappropriate to close it.

please all users to stay on topic and do not exit off topics.
Thank you

I don't understand the "5" option of the survey, can anyone explain it to me?

Dear friends,

I've read all the interventions you've done and I've been a little hurt. I believe that the discussion is derailed despite the advice and constructive considerations of some of the most active and prepared frequenters of the portal. seldom these friends deny help to those who ask and rarely raise tones. I do not want to judge anyone (it is not in my possibilities) but I point out that it would be correct and anyway "selective" to settle for what you agree to recommend proposes. this help can be insufficient from the point of view of those who need it and can be cost many minutes of free time of those who try to help. ask too much risks indisposing those who want to help (they are many who help without asking for anything in return, in the spirit of disclosure that borders with the highest generosity) creating conditions to vanify an intervention of help to another person who perhaps desperately needs it. Therefore I pray (it is a true prayer, not an elegant way to say "do so") who asks to be moderate in the demands and I ask who helps to continue to be "generous" as it has been until now. Let us remember that together we contribute to the growth of many younger colleagues or only less experienced by giving advice and giving examples of collaboration.
Thank you all very much.

I imagine that choosing option 5 means that there is no person more prepared than ourselves.. .
we say that there is a good pinch of modesty.. .

 

[panormus]

Ooohh my professor. .a noble presence (and I also speak with the heart trying to be always truthful).. the blame is also his of all this: because of him I managed to model and work from nothing, from the tabula rasa with the most complex modeler that there is on the market attracting me the negative criticisms of those who told me you will not make it, it is impossible and those of those who arrived to do something, although perfectable surely has repeatedly told me that the job is bad.
the second fault is to have me passionate and made understand that nothing is impossible if you put yourself with passion and commitment;
Another fault: not having published a second volume to allow me to further advance.
As for asking too much is something I do mine, I accept that my desire to know can be indisposable and if so it was I apologize to all those who have lived this indisposition, but the desire to know and ask today is concrete also in the forums, where it is lawful to ask and where I expect the answer, if there is courteous.
that my work is defective is clear, it does not rain, and the treahd is born to ask how to solve and how I do not think I have found precise answers, but lately only interventions in which I read "it is not, it is not a faithful repeated" that I care secondaryly.
It is good second to invite also to those who have friends rooted with the leadership to be however kind staying in topic looking at the moon and not the finger.
Sorry, it's my real intention to be friends with all of you.
Have a good day.

ot:

I think it is not taanto the speech to settle for the advice you can receive, here the problem is that the user who opened the thread did not understand the message, and as if I went to the pizzeria and the pizzaiolo asked me liked you? and say no to me and go for pizza!!!!
:

 

[panormus]

And no, that's not the way it is, I opened the poprio treahd because I wanted to do better.

 

[Counterblow Hammer]

Yes, but you want to do better on a topic (modeling surfaces) whose learning cost us all time, blood and sound splits of assholes (to some money too)! I am well to use the forum to ask for advice or a little help, for charity we are here in the mail! But as you set it up recently, it went a little further... Do you really want to make serious progress on advanced surface modeling? from courses to manuals the systems are there, but not sure by cuffing on a forum! because as I repeat: this topic to be assimilated needs blood! and every one of us cares about our own blood. . .

I hope I've explained... Have a good day!
