Note: By setting the Rake “Ascend” Preference (see Preference Settings on page
83), you may view Rake-Wall stud lengths from smallest to largest size.
Note: You can also solve if you only know the Rise and Pitch, Run and Pitch, or
Diagonal and Pitch. Simply enter the known values via
p , r , R , or d keys,
similar to Step #1 above, then solve for Rake-Wall stud lengths, as seen in Step #2.
