Nominal Weight of Structural Members

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.

and it is not only that. There are massive differences between families of same category - naming, units, organisation etc etc.

Agree whole heartedly with you. 'kgf/m'  is a non-standard unit and is adopting the wrong unit for the value given. All steel tables relate to values in kg/m. Having to divide the result Revit gives you by the value of gravity is needless.
