conversion of cylindrical metal surfaces

[dany-h]

Hi, guys.
I'm making a mould for a polyethylene tank to be made for rotoforming. I modeled the finished piece, climbed it and now I should convert the outer surfaces into sheets to develop them, laser cut and work with the press or grill. the problem is that I can't turn them into sheet metal using the command converts to sheet that doesn't seem to work on cylindrical or conical surfaces. (I also added a planar side)
use sw 2011 sp5 32b
Can someone please help me?
Thank you in advance.

hi I use the command "insert folds" and not with "convert the sheet"

you can do it directly with the sheet using the loft between two sketches... .
But... always that you do not claim to realize even those "cylindrical abortions" at the ends of the conical part in a single piece. because of course you will know that that detail is unrealizable for displacement and/or simple displacement (it is only this that makes the module swx sheet); serves a "printing" or a roller, things that the program does not contemplate; only forms that have a normal known development.. In this case it is logical that you do not allow the operation, those cylindrical edges should add them for welding.

of course the mold will be formed by cylinders, cone logs and flanges welded together. using lofts I should recreate all the sketches seen there the solid comes from a revolution; which would be very long. my purpose is simply to find a function that allows me to click on the surfaces (before the cylindrical ones, then the trunk-conic etc-ecc) and to generate a removable sheet.

Could you explain to me how you use "insert folds" on a cylinder? seems interesting... .

thanks to everyone for the attention

Suppose you have a ø30x1 l100 tube made with the usual basic extrusion, which I want to transform it into sheet metal, I make an extruded cut of 0.2 mm as fig2 at this point I click on the command "insert bends" and on the bending parameters select the edge 1 that on the øest long100 mm parallel to the axis of the cylinder with factor k =0.5 and it turns into sheet metal now you have to see if you can see the solution

Thank you in advance.

if you already have the surfaces, you can "inspect" (instinguishing function) and then turn into sheet metal.

you can directly extrude the arc with the "basic flux" sheet function, but you definitely know it. :smile:

Hello everyone

this suggestion is fantastic.. sin that however does not work on trunk-conic parts (however I learned a function that I did not conocseve). Thank you

if you already have the surfaces, you can "inspect" (instinguishing function) and then turn into sheet metal.

unfortunately also this does not work with the trunk-conical parts

At the end I rebuilt the sketches coincident to the surfaces and made the sheets again with base flange and loft.

thanks to all for the intersection
