Hello
I have a small question about "process" concerning the design of a vehicle.
I made the shapes and surfaces of my aircraft via Imagine & Shape, which allowed me to do the aerodynamic simulation.
On the other hand, to do structural simulation I need to have my plane composed of several solid parts, with their materials, like a real part.
Do you know which apps we usually switch to after going through Imagine&Shape or GSD to continue and therefore go from shapes to solid assembly? Please. Would there be a doc or a scenario on the design of a vehicle from A to Z?
I know the apps Part Design, Assembly Design, Material, etc...
Hello
PartDesign Workshop: display the "components from a surface" toolbar.
Of course, if you want to get an ASS, you have to create it first.
A lead ASS then a Catpart per piece
You import your file into the ASS
You copy and paste the surfaces you need successively in each Catpart
With or without links (it's up to you if you need to update).
After that, it's either surface thickening, or filling, in case N° 2 your surfaces must be closed (in order to be able to transform them into solids.
Hello
Thank you.
What good is the Close surface tool if it asks me to already have a closed surface?
Hello
Under Catia I don't have this function.
By default catia tries to plug the holes with a flat surface.
For example, if we draw a cylinder (extrusion of a circle) in GSD, the ends are open but it is not necessary to close them. In PartDesign the fill function will automatically plug the ends with two flat circular surfaces.
EDIT: In your case you have to close manually.
I can't find the fill function.
If I close them manually I would only have a simple envelope but I would like to have a solid of a certain thickness to insert a spar in it etc...
This is the icon on the right in the toolbar (Part Design workshop).
You can also use thicken the icon on the left. (check that the geometry at the opening corresponds to what you want), otherwise prefer filling and then a shell to hollow out the solid
ok but nothing works:)
For 1mm up to 3mm it works but beyond that no
OK
Hello
Without seeing all the details of your surface (possible defect).
This is normal behavior! Except for a flat surface, there is always a limit to an offset.
As we can see, the division changes.
At the top of the shape there are still two faces forming a V if I increase the offset again these faces no longer exist this is the limit, and the warning message you have .
It's definitely towards the tip of the wing.
You can:
- Reducing the surface area to pass the thickness outwards...
- Fill and try a shell (little chance of success!)
- Create a shape from offsets to dig the wing.
Ah thank you for the info.
I tried to thicken on the outside and it works.
In fact he must not like the different facets of my wings and inside towards the salmon it must be a problem. I tried uncorking the kite and it works.
So how do I "fill"? please just to test.
I didn't understand how to "create a shape from an offset"
On the other hand for the half wheel fairing it doesn't work at all
I have examples in which you have complex shapes and the thicken function doesn't seem to be a problem.
So once the surface is thickened I can work it as a part? make holes in it etc? Stp
When I click on it in part design it offers me almost nothing.
1: Yes, thickening each surface tile gets bigger so it works better.
2: To complete:
Either you create a surface in GSD 
that plugs the opening and then assemble it before moving on to the next step.
Either you try directly in PartDesign 
if the opening can be blocked by a flat surface it will do it.
Create from an offset:
You first create an extraction of your surface (the wing).
You cut the part that seems to be a problem
You create an offset surface. 
Then you plug the extremities and you put it all 
together.
Finally, you make a section in PartDesign of the filling solid created earlier.
I'm not sure if I can open a file from the 3D Experience.
But we can try , put me the CATPart and a second file registered in IGES.
A surface can be complex but have a geometrically simple tile cut.
A surface that looks simple can have a complex tile trimming.
Taking as an example the opening of an STL file, the cutting into surface tiles related to the mesh is often very complex.
There can be several reasons in PartDesign:
What function are you active on?
The selected mouse pointer selection can be the GSD surface not the solid surface (hide the GSD surface).
The hole function needs a flat surface of a plane, this is not the case for the wing, it is necessary to first create a support plane either for the hole function or to be the support (plane) of a sketch.
And one in IGES3D.
Thank you very much in any case, it's nice to take the time to explain to me:)

Hello
When you use the "thicken" command and CATIA opens the warning message, then (Ok), just say yes to the "Disable surface and extract its geometry" command prompt.
Catia creates the surface offset only of surfaces that does not give it a PB.
So we locate the areas with PB (they can be very small , go to "Tools/Options/General/Display/Visualization/Surface Edge Style"activate).
Any very small open edges will be easier to detect in wired mode.
After that, we will have to recreate a geometry to fill in the gaps.
Attached is a video of a quick way to fill in.
If the thickness tolerance 10 is not too tight.

Ok thank you very much. Very well explained. I'm testing that.
