After a design is performed, the program collects identical wall assemblies into wall groups, and assigns a number to each group. The complete material specification for these groups is listed in the Sheathing Materials by Wall Group and Framing Materials and Standard Wall by Wall Group tables of the Design results.
The group number that a wall belongs to appears in the following places:
You then refer to the Sheathing and Framing Materials tables for the wall specification corresponding to the wall group number you see in these places.
In the case that you have designed for rigid and flexible diaphragms, but not selected worst-case rigid vs flexible in the Design settings, then physical walls can belong to more than one group because they may be designed with assemblies for different distribution methods. In this case, the program lists the wall groups that the wall belongs to like this: 1,4.
The wall grouping described above happens whenever the program finds walls with identical materials; you can also force sets of walls to be designed with the same materials using Standard Walls with walls having Design in group checked. Refer to Standard Walls for more details.
The correlation between standard walls and wall group numbers is shown in the Framing Materials and Standard Walls by Wall Group table. There are also numbered wall design groups that do not correspond to Standard Walls, either because the walls were not created with a Standard Wall, or Design as a group is not enabled for those walls.
It is possible that the program determines that walls created with a Standard Wall and those that were not, or walls created with two or more Standard Wall groups, have identical materials. In that case, it assigns the same wall group number to all these walls, but lists each Standard Wall separately in the Framing Materials and Standard Walls by Wall Group table.
