Hello everyone,
I would like to make a sheet metal piece like the hood shown on this site. What I want is 4 pieces of sheet metal to weld them corner by corner.
http://www.solidxperts.com/blog/fr/solidworks-fr/comment-creer-une-piece-de-tolerie-a-corps-multiple-avec-la-commande-convertir-en-tolerie
I create my model (modeling, hull etc.) then I make my first sheet metal parts with the 3D sketches on edge for cutting and when I make the 2nd sheet metal part, SW tells me "impossible to apply a cut or a notch"
If you have another way to create my pieces it's welcome!
Thank you!
Hello
In which version are you and can you post your piece?
Hello
It is sometimes tricky to start with a classic design and then convert it into sheet metal work, especially if you use 3D sketches. The best thing to do is to start with a sheet metal design from the start, it's much simpler. Looking at the hood presented in the link I didn't understand everything about the 4 pieces you want welded. However, having already had to model a kitchen hood, I am sending you a draft that you may or may not be inspired by. I did this modeling in the form of an assembly, an approach that is always simpler, especially for MEPs and the links between dimensions, than that of a multi-body part. The dimensions taken are only given as an indication of course. There are two rooms. The tube made with 4 successive plies, one of which is symmetrical and then a silk to make the junction (there is no circular sheet metal part otherwise unfolding would be impossible). The cone is based on the transition fold function based on the internal contour of the tube (external reference), a preliminary construction sketch determines the opening of the cone, here 120°. There is also a silk to finish the piece. I added a few connecting tabs to connect it to the tube (adjusted by editing each sketch after selecting the corresponding edge in the "fold on edge" tool).
Hoping to have helped you a little

Hello again,
I hadn't fully read the proposed link. Indeed the 4 pieces seem better to me. I redid the tutorial described without any problem, I have SW 2015 SP5.0. Check the box "keep the body" otherwise it will not be possible to generate the other parts, and of course make a 3D sketch by edge (4 sketches in all). I couldn't find the error message you have.
This led me to think about another possible design of this hood, a design that can be a little easier to visualize, still in sheet metal of course in order to benefit from the flattening. I am attaching a description of it.
