I believe that's a deliberate choice by Siemens that all the SM bodies have the same thickness, so if you would like something different you'll have to do an enhancement request.
What's your use-case? i.e. you'll only get one flat pattern out of it so you can only have one 'fabricated body' unless you're doing something interesting..?
A different thickness would mean a different material. Unfortunately, bodies in a multi-body part can't have different materials. I wish it weren't so.
The material thickness is also a parameter in the variable table - so I doubt having different thicknesses would be possible.
I have encountered a few cases where having the capability of different materials in a MBP would save some hassle. I wanted a part that could reflect the mass of different materials. As it is I had to create assemblies (the hassle part) to do what was needed but I didn't need assemblies other than to accomplish that.
Why not just make them in the part environment, then after publishing the individual parts go into each and convert to sheet metal at that point?
thank you for response,
Well, this is another trick / different way we can use to achieve our targets - but it is not a solution to this ''bug''.
There is no ideal world, so we have to keep fingers crossed for getting access to change the thickness in another release ( maybe ).
...but it is not a solution to this ''bug''.
Not really a "BUG" though, when it is clearly working as designed!.....you'll need to work in the context of an Assembly, to achieve what you want to do with different sheet metal part thicknesses.
