Bolt Length cannot be calculated

Hello All,

I created a new flanged end prep type, joint type, end prep type  ISO map, it works fine in OPM and ISO.

The content I created, I copied from standard flange, all contents are almost same as standard flange except the end prep type (FL Vs. FNG)

The problem is the bolt length cannot be calculated if my end prep type FNG used. I am guessing when OPM calculate bolt length, it may not get flange_thickness since it is a new end type which OPM doesn't know it. How OPM get flange_thickness?

    Sorry that article cannot help me. It explained how calculate the bolt length, my problem is it cannot calculate.
    For example, Stud Bolt_Length = (Gasket_Thickness) + [(Flange_Thickness) x 2] + [(Nut_length) x 2] + [(BOLT_XCESS) x 2]
    I'd like to know how to get "Flange_Thickness"(maybe Gasket_Thickness as well, no gasket for my end preparation) value . I am guessing OPM cannot get it from my new end preparation FNG. Thanks.
