@jpai, next time attach the native SolidWorks file (if there is no notion of confidentiality of course !!) and you will see as if by "magic" the part will come back to you in the unfolded state in less than 2 !!!!! Lynkoa = ten times faster than Chronopost!!!!
@ Lucas, I have the sheet metal function, I just need to learn how to use it:P
@ jfaradon, indeed the filter is in 3 parts. The bottom will be welded after the cone shaped sheet has been wound and the cylindrical part will no longer exist, it will be replaced by a flange which will be welded to the cone afterwards.
@ Bart, yes that's what I want. But for my detail plan, I need both versions... rolled up (welded) and unfolded :)
I drew the part with the swept sheet metal function, which is nikel.
On the other hand, this function does not exist on solidworks 2012, you will have to convert it from parasolid format, to sw2012 format, then to sheet metal. Which I have no doubt, should not cause you problems =)
Good luck!
PS: For everyone's information, the sweep sheet function does not manage the "unfold" and the removal of material.
And wouldn't it be enough to calculate it by hand?
Too often we rely on the functions of CAD even for simple things. We spend more time finding how to do a manipulation on the CAD rather than doing the math the old way.
