    Modelling a steel Open Web Rafter

    Hi All,

    I am wondering if anyone knows how to model an Open Web Rafter like the one in the attached portal frame drawing?
    I am not great at modelling families so I am unsure where to begin.
    We make them out of Square Hollow Section (SHS) steel like 75x75x3.0 or 100x100x4.0 and they vary in overall depth and length but I don't know how to make them into a family that I can use the family over and over again.

    Make some truss families to suit. The ootb ones dont cover much.
