I figured out how to start this part, but I still can't draw sketches on the unfolded model while keeping the extrusion functions in folded mode...
Basically, my raw and flat sheet metal will be laser cut. So I would like to make my (many) cuts in the plan, in a single sketch. And then to be able to find this extrusion in "rolled" mode so that the cut-outs appear in my assembly. That's where I get stuck!
See my example in PJ, the extrusion is located after the unfolding function...
Basically, how do I keep the cutouts when I come out of the unfolded state?
Sorry for my ignorance, I almost never do sheet metal, or at least I usually always have a flat portion. here it's entirely cylindrical (rolled sheet metal)
On the other hand, last trick question! how would you do for this kind of room (in PJ)?
a crankcase in a flat sheet metal with just the slightly rolled end.
Always the same, how do you make the laser cuts in a single flat sketch? And how do you roll the sheet metal over a small portion while keeping the previous cuts?
I think you're taking the problem the other way around: usually you need a rolled part with cutouts that allow you to perform functions.
So that's what you draw, then you use the sheet metal function of solidworks which will put your part flat (and will therefore deform your cutouts). The final result won't be exactly what you drew initially (because the cutting is done perpendicular to the sheet metal, so the cutting edges are deformed after rolling), but it will look like what you will have in the workshop.
Sheet metal parameters (facetur k, bend loss, etc.) slightly change the shapes/lengths of the cutouts and unfolded. They depend on the tools used to roll/bend the sheet.
That's exactly what I didn't want to do! (to make it more or less!) ;)
Now I have a theoretical and dynamic model, compatible with my assemblies and drawings. That's what I wanted to do! I thought it was possible in sheet metal but apparently, no. So that was my mistake!
