There's an inconsistency in all the BS4 Steel Members lookup tables - it could apply to other steel members too.
The Nominal Weight Parameter unit is given as "kgf/m" (which an unacceptable non-SI unit) but all the Nominal Weight figures in all the tables show the kg/m values. It's a useless value making the calculation of member masses for tonnage calculations needlessly complicated.
Either:
- Change the built in family to support a "Nominal Mass" or "Mass per metre" parameter with a kg/m unit replacing the "Nominal Weight" parameter. The values in the lookup tables can then stay the same, just change the headings & units.
- Change the "Nominal Weight" to the correct N/m or kN/m unit AND then change all the lookup tables to show the correct weight per metre values.
