4” Thick Lumber Beams (v9 - Feature 187)

The program now includes a database file for 4” wide lumber beams. Because the strength properties are different for lumber materials (Table 5.3.1A) than for timber materials (Tables 5.3.1C/D), you must select lumber materials separately from timber material and it is not possible to cycle in the design search from 4” to 6” and wider beams.
