create solid starting from the sections!help!

[0063966fra]

Hello everyone, it's been a long time since I started using catia v5 for modeling and analysis of structures and I have a problem from which I can't even get out reading the guide. I am trying to generate a solid of which I know the sections, so I drew through the scketch command the sections on different planes not coincident to then join them through the command "volume from sections" the problem is that if one of the sections is actually formed by two polygons closed but separated between them the command from error and tells me that the section has to be connected in the sense that it has to be formed I can from one polygon or the same closed profile, the solid that I try to model is a parabolic arc whose section is in the central part unique but in the terminal parts biforca! I hope I have explained my problem and that you can help me thanks to all!

Hi.

...if you can post the file, maybe we can help you... I think I figured out what might be the problem... but so blind I don't know how to help you.

I have completed the job until I stop. how can you see from the screen when opened the file I managed to connect all the sections of the first section but at the time when the section separates in two I can't join them! Well this already I said it sorry but I can't load the file I have to make screenshots? Here they are

first avoid using the gsd volumes that is taking you off the road
the form you need to use is partdesig
find multisection function
which is composed in the sixth way of what you used
now your problem to that from a section you have to converge to a section that has a convergence point, and subsequently diverge.
duple the last three sketches (copy/paste the sketch)
split the first section the two parts then apply the multisection command with top-type coupling.
In my opinion there is also a more direct way, breaking the model into simpler sections, but I should have curves.
Hi.

Thank you very much for the advice, I did not know that it was wrong to work in gds, regarding the question of the curves I have to define them because apart from the dorsal that is a circle arc I thought all the solid working for sections from the beginning. Thank you very much for the advice!

It is not that it is wrong (you would do extra work), but if your purpose and create a solid so much it is worth modeling with solid features.

hi and good work
