build a sheet metal hood

everyone, someone can explain to me the process of building a hood that has as its base a measure of 600x500 with a height of 450, and the arrival above always painting of 200x150. mamiera thickness 15/10. Thank you for your help.
 
you have to do the volume as a simple feature using extrusion and cutting as main commands.
then when you see that the shape of the feature corresponds to that of the hood that you have to relalize, apply the "empty" command in order to obtain a thin thickness equal to that of the sheet. in the command empty, exclude all the faces that you do not want to be involved in the cape, that are part of separate components of the shell, that you will go to realize separately with the same method. at this point use the command "insert folds" present in the sheet metal toolbar. you will see that the cloak acquires fittings and bendings. insert discharges, fittings and tolerance limit that you feel right. at this point completes the cloak with the command "flange of the edge" to create the lines of the filters and the various lembies and cuts necessary to accommodate and insert the electrical components, to assemble the other pieces of the shell or for the robustness etc. select "external material" inside the flange command of the edge always. do all the holes you feel necessary for assembly using "fold and explain" or editing the sketches of the flags realized.
with the same method realizes all other components such as fireplaces, brackets, ceiling lights and backs and everything else depending on the model you have to make. assemble everything.
create dxf drawings of the cut in which you will put the individual components in scale 1:1 and of course selecting "flat repetition" in the orientation of the view and removal of the hidden lines. reopen the drawing clean the dxf from the drains, from the bending lines or from any holes axes etc. you have to leave only the perimeter of the single-line development of the cut and for the cut. It creates bending tables also a4, comprehensible for the folder in dwg or pdf format for each component highlighting the bending lines on the floors and its correspondence on the folded. consider that (it is convention accepted by many for simplicity) that the bent corresponds to the quota of the bending line plus the thickness of the sheet all over the bending line and towards the folder. That's why I told you "external thickness" in the flange command of the edge. the fixed face of each fold is the one that remains under the folder during the bending for which if you do the sketch bends" consider that changing the fixed face you get different results in the position of the thickness regarding the bending line and also change the orientation of the piece in space, often in a uncomfortable way for the untied putting. the folds are performed by the folder almost always from the outside to the inside of the cut-out floor. also uses the assonometrics in the bending tables and the bending notes to make the correct bending direction clearer than in the without protective cuts could be wrong.
 
I add that to make already cleaned dxfs for laser cutting you can save by name directly the 3d model of the sheet in dxf. you just have to select whether to include bending lines or not.
 
thank you for the celery answer, xò I sent you the design in part format, in which I stopped when you arrive in the command insert bending, since the command is not clickable. How can I continue? Thank you.

the solid you posted cannot yet be turned into sheet metal, first you should open a edge. control in the functions of sheet metal, there is a fact on purpose.
after opening a corner you can select a face and press the command "insert folds"
another way to do the same and do not empty the solid and use the function from solid to sheet (only from 2009).
 
Excuse me again, the opening of the edge through the command "opening edge/accorcia edge" does not work, that is nothing happens. I'd ask you to show me an example with the various steps so I can see. Maybe I'm reluctant! thanks to vs. availability.
 
see if this example can help you,
Keep in mind that I can't use the program

Hi.
hi, you solved the problem of devis in the sense that the hood opens properly. Keep in mind that in solidworks you usually keep the insertion bar at the bottom of the tree, otherwise when you open a set, you will see signs.
in the case of solidworks sheets automatically creates a derived configuration for development. This configuration is created when you put it on the table or when you get out in dxf as you did.
the flat repetition function is normally suspended and in the flat configuration is activated and the sketches of the fold lines are displayed.
I also attach a file where I create the hood with the edge laceration and not with the solid convert command.

Thank you for having solved the problem, I must say that the example you have done has been satisfactory to the max. Thank you.
 
in response the message: "I add that to make already cleaned dxfs for laser cutting you can save by name directly the 3d sheet model in dxf. you just have to select whether to include bending lines or not"
from the 3d model I clicked on "Save copy" but in type selection I did not find dxf format. should I select a different description? Thank you.

Home file you have to click save by name. see the list of file type and look well that there is dxf and dwg.. It seems to me down.

greetings
