I would like that Onshape give me the exact K factor while I'm modeling sheet metal part when I insert thickness and bend radius. How can I do that ?

    This isn't supported in sheet-metal yet. but I have an easy workaround i use on a daily basis.
    FS:Sheet Metal Bend Table | Test (onshape.com)

    make a copy of the above document

    download the CSV and edit it.

    if you add more rows, make sure you add those rows in the code as well

    re-upload the CSV by selecting the 'update' option.

    now just insert this feature before any sheet-metal feature then you can just use the variable "thickness" "bendRadius" and "kFactor" in the sheet-metal feature.





    you can see here that this just adds those variables into the part studio,
    there in an option to put a prefix in front of the variable name if you want to set some thickness standards for the entire project.

    @Luca_Loretti, is your intent to create your own custom k-factor lookup table?  Because my understanding is that k-factor is very much dependent on material properties and tooling.  You (or your sheet metal vendor) will likely have to run a series of bend tests to determine the relationships between material/thickness/bend-radius/k. 

    Hopefully @bryan_lagrange or one of the other sheet metal gurus in this community will chime in and correct me if I'm wrong.
