    steel section detailed dimensions for CAD & FEA

    Howdy,

    I'm working on designing some steel structures and I'm referencing the AISC ASD 14th ed as well as ASTM A6 for section shapes. I'm having trouble finding exact dimension call outs for radii and flange inside angles for channels, angle shapes, and M sections. Can someone please help? Am I missing a spec? I'm trying to create my own 2D section library for reuse.

    I figured out the answers to radii and for the flange angles (12/2).

    What I haven't figured out is the flange thickness for the c-sections. What's reported is the average flange thickness but how is that calculated? I'm not finding this documented anywhere. Thanks!
