Creating a Truss Family

A truss layout family consists of lines that define truss elements such as chords and webs. Chord and web members are created such that their center lines (local x axis) will lie along the layout lines that you define in the truss layout family. The entire layout will be transformed such that the distance between the 2 end reference planes will be determined by the truss instance based on its shape in the project. The Length parameter may be used in your truss layout family to perform calculations to specify the exact location of vertical web members or to calculate the number of panels to create in the project environment.
