For example, BOTTOM CHORD L3.5X3.5X0.375 FOR GROUP 2 indicates the bottom chord of bracing group 2 is L3.5x3.5x0.375.
Bottom chord shape type to be selected in the design generation of a given bracing group (see FOR GROUP i, j, ... ) is to be selected from either W, WT, L, 2L, C, or MC. For example, BOTTOM CHORD L FOR GROUP 2 indicates the bottom chord for bracing group 2 is to be selected from L shapes.
