Hello
I drew the hull of a drone, I changed the dimensions and I can no longer rebuild my object. The object does not take into account the new dimensions. Can someone help me please? I have attached my Catia file.
nathasha.catpart
nathasha.catpart
Hello, I opened your file.
I don't have any update requests? it is saved Before change or after??
Need + info on the modification
Sorry I had attached the wrong file. Here is the coordinating file.
Yes, I saved it after the change. If you look closely, the circle in sketch 20, for example, is not taken into account in the final object.
nathasha.catpart
At first glance it would be normal sketch 20 has no children??
I have to relaunch a CATIA version in hybrid mode to be sure.
We meet again after lunch
Kind regards
Edit it's better with a screenshot
I restarted a default installation and hybrid mode (just to be sure that our settings didn't set a PB).
I confirm the sketch.20 has no children, so since nothing refers to or relies on it, the modifications of this sketch have no effect on the rest of the geometry.
OK... But what should I do? I just started using Catia and I'm having a bit of a hard time...
These the face I selected that you want to modify?
For this face is created by the filling.10.
What do you want to do with the 20.22.23 sketches?
Edit : Forgot the screenshot again
Uh... Basically, I want my object to change as soon as I change a dimension. Not just sketches 20, 21 and 22
Basically, I have to study the aerodynamics of this hull by varying the dimensions of the circles in sketches 11, 24 and 25 on the one hand and then 20, 22 and 23...
Well it works very well if I change a value it changes.
even on the sketches 20 the diameter is modified and the circle is enlarged.
I changed the values of the three rays that form the outer flange, no PB of course within the limits of the functions that were used to build this shape, if we go too far, it doesn't work anymore.
Now I'm going on training, I'll be back tomorrow.
Thank you very much for your help! But do you manage to thicken the pudding? I mean, no matter how much I change the radius of circles 20, 22, and 23, I feel like it doesn't matter. 11, 24 and 25 work.
None of these sketches were used to create the form.
they therefore have no effect on geometry.
See you tomorrow I think I'll see what you want to do, I'll look at it tomorrow.
Good evening
I just understood the story of "parents - children"!!! But I don't see how to connect my circles to the rest of the object at all... All in all, it's really nice to help me. See you tomorrow
Good evening, I'm at home so I don't have access to catia but in the meantime in view of what you want to do, I assume that the radii of the 3 sketches 20.22.23 will evolve at the same time as well as surely many other constraints or parameters, so look at this tutorial on equivalences it should be useful to you
http://www.lynkoa.com/tutos/3d/catia-v5-fonction-equivalences
the video is a bit long to load (patience) except under Chrome at work I can't display it? under FireFox it's OK.
Another tip you have an fx icon not very far from the one of equivalences.
It is used, among other things, to create user parameters, it's more convenient than searching in the graph.
In the drop-down list, you select length, you give a value, you change the name, ex entre-transmission, then you validate.
Watch the following tutorial (the first video)

Hello as an attachment a video showing the proc for adding sketch 24 in the multi-section surf.
Sketch 11 was already done.
I would have a remark, the extremes are not controlled, hence the twist of the surface.
They should at least be oriented in min or max on Z. (be careful, it will necessarily change the surface but in my opinion the current twist is not a good idea.

Hello
Thank you very much for your help! I just had access to Catia again. That's really nice of you!
