CATIA v5r19: grrrrr surface

3D Design Volume Model
1

Hello

 

I have a part to do as part of a project, a the hull of a remote-controlled helicopter, not knowing the surface at all and needing this tool (I tried for 1h30 in vain lol no successful scan) to make the shape of the hull can you help me, I think I used the sketch tracer in order to have the primary forms etc.

Fortunately you don't absolutely have to have the same exact geometry but they must be functional for assembly.


On the sketch tracer I put a 9 cm long rib (the longest rib), the rest is determined by CATIA :D!
Here are the pictures: http://hpics.li/d3e84f1

 If possible, show me the procedure to follow, how you would proceed/if you are motivated to start modeling.
Thank you very much for your help! Any help is good to take!!

Hi @ honcaumut

 

See this link to Catia Surface tutorial

Look and understand the why and how

By doing a search on the FOFO you will also find CATIA tutorials I posted them myself

In theory with that you should get by

Good evening

 

uses an icon that looks like a tunnel

 

you find the same in solid multiple extrusion its looks like a rib

 

You will need several parallel equisse.

 

I'll make you screens tomorrow morning @+

Hello.

CATIA surface there are two modules
1 (GSD you build the reinforcements, Ctrls points and Tgt elements to modify your surface) with this module I don't recommend you to use the sketcher because you limit the ctrl of your surface because of the "plane" sketch support).
It's tedious but it's better to draw the waypoints of the guide curves, it gives you more freedom to improve your design. Also be careful with the use of symmetry, it's practical, but if you haven't defined the curve well, at the connection on both sides you can have PBs of tgt.
2 (FREESTYLE I don't have this module).
I'm sending you a private message because I can't access your photos if you can send them to me by email.

Thank you very much for your answers,

I'm a taker of some well-built tutorials, but if you could give me the basics, with screens etc for the design of this case since I'm in quite short time, it would be really cool:D

 

@gt22 acc I'll take a look, thank you

@Fréderic, thank you I'm looking forward to it =)

@Franck, I contacted you by email for the photos, thank you

 

Kind regards

Hello;

 

What is the part that you can't model?

 

Kind regards.

 

Cédric.

@ Cédric - Well nothing for the moment because I really know nothing about it, every time I try scans, it doesn't give what I want. That's why I would like to be given the basis to understand how it works

Hello I think that if you use the multi section surface command you will get to your result.
The idea is to build the curves of the passage of the surface.
Have in mind to control the tangencies at the ends of the curves, and that the fewer points there are the tighter the curve.
I gave you an example (quickly).

A very important detail in surface area that often means that an operation does not go through, it is the direction of the guides and curves as well as the starting point possibly if there are any.

Often it happens that it doesn't fit because of that.

It is materialized by a small red arrow starting from the origin of the curve. We have to put it in order and make tests!

 

There are quite a few ways to make surfaces on CATIA.

A rule to remember: break it down into several surfaces as soon as it gets complicated, cut and assemble.

Happy New Year

 

I have a problem with the modeling of the 2nd part, how to model it and how to make it transparent? Thank you

Have you taken the time to look at the tutorials I posted above?

 

everything is indicated so look at the tutorials and you will have all the answers you want

 

who de+ is if you block somewhere take screenshots and post them+ easy to understand with a drawing only by speech

(A DRAWING IS WORTH A THOUSAND WORDS)

 

Don't forget to write down the answers that provide concrete help (the green +)

It's a pleasure and encourages you to respond

Hello and best wishes for 2014.

Can you put the CATPart file so that we can see where you are, and a photo or a drawing for the part where you are stuck.

To apply a simple + "transparency" property, right-click on the element and then  (in the window, select "properties" and then move the cursor).

 

See attached image.

Hello.

Attached is a solution for the screw housings.

Personally, I make the design surfaces and switch to PARTDesign as soon as possible, so I would tend to treat these shapes of revolutions in volume and then add them by partial relimitation on the hull or the thick surface.
To define the tangency directions at the crossing points of a spline, I put a video tutorial, click ICI.

Note: join the group CATIAV5 this is the best place to discuss volume/area advantages.
