update:
tool of revolution made!
now I have my wing which is built through surfaces!
I built a plane at one of the ends of the wing!
Follow me: I built a rectangle on that floor and then I clicked on the fill command!
Now I have to delete the common part between that plane and the end of the wing, which is nothing but the end profile!
How do I do that?
I have wildfire 3.0!
greetings to all and thank you!
you have to make an intersection between surfaces.
 
I use the wf4 and then the file wouldn't be able to open it, since you use the wf3.
Anyway, I made you a movie to show you what to do.
the fill and the sketch you used at the end do not need, in fact you have to delete them.
the function you need to apply is the merge (join the Italian version).
select one of the two surfaces, hold ctrl and select the other and apply the command, finally selecting the material removal direction (yellow arrow).

Is there any particular reason why, after the operation of union, the import of such design into star ccm+ environment does not recognize me the revolution of the profile?
I didn't care how much it was.
I really don't care!! !
Hi.
Lorenzo
 
have you tried to make the merge between the surface of revolution and the two previously united?
 
then the revolution as it is done is not good because there is no correspondence between profile, extrusion and revolution!!! and I do not understand why among other things!! !
export to star environment (I tried both in iges format, step...) is bad in the revolution (it is the classic problem I think!!!).
Do you have any advice?
I solved it for the matter before!
I attach the files (image jpeg and file for proe)!
Hello and thank you

I checked the model in pro/e and managed to solidify the surfaces you made and this means that there are no discontinuity or "holes".

I don't know the star, so I can't tell you what the import problem is.

I think about the precision used by default stars, in pro/and default accuracy is 0.0012.
 
Everything solved!
Now I can finally start another chapter!
an information:is there a fluiddynamic analysis section of wings?
can I open one?

Hi.
Loire
Would you let us know what the problem was?
so it can be useful to other users.

a section so specific does not exist, you should search in the section cae/fem/cfd.
 
I set the setting accuracy in the star model...
when I amount a drawing from proe (and from any 3d modeler) star asks me some parameters to set including precision precisely!
"tessellation density" and "sewing tolerancence". . .
playing with these two parameters I improved "the bad thing" before!!!
That's easy!
then for the union I followed your advice and I joined in proe the extruded part and that of revolution! ! !
hello and thanks again
Loire

ps:the error resided in not having joined the surfaces so that the two surfaces interpreted with their original lines of construction and not united:it is because in my opinion I got that problem exporting everything!
 
Hello Maxoplus!
I reopen this thread because it needs the following help and explanations:
Remember the wing you helped me generate?
then I wanted to understand the following things:

-Is the part of extremities generated with the instrument of revolution improved? in the sense how the revolution is generated? I make you an example to explain to me (if I zoom out at the edge of the revolution is divided into many areas; in practice if I look at the exit edge I see many segments inclined to reach the revolution of 180°): my question is the following: is there a possibility to increase such segments, and of consequences to increase areas?

- then I have to translate the wing of an offset and I have to rotate it of an angle! how do I do?

Thank you.
Lorenzo

segments you see are just a display limit, if you increase the viewing quality you should see the revolution surface without segments.
geometry should be correct.

On the second question, I look and let you know.
 
Greetings to everyone!
I'm going back to putting a post because I need help!
I created a wing starting from a Naca profile connected to the tail!
then I created a surface to join the wing!
I can't do this union (the part of the wing in the tail does not seem to be connected in the surface!!!).
Obviously the surface must be hollow in the area where the wing is overlapping!! !
If someone helps me, it's a great pleasure.
I put the file to open on the net as well!
Thank you.
Lorenzo
