are true: 1) Common and Irregular Pitches are not equal and 2) Jack Alignment
Preference is set to MATE, rather than ON-CENTER.
** Tail Lengths shown only when Horizontal Overhang is entered.

sTair funCTion

note: Within Preferences, there is a setting for Riser Height that
determines which type of calculation will be used. The default is Target
Riser Height.
• target riser height: Use this setting to get a stair calculation that will get as
close to the stored Riser Height as possible. The calculated Actual Riser Height
will either be shorter or taller than the Target Riser Height.
• Maximum riser height: This is used when local building codes prohibit risers
greater than this value. The calculated Actual Riser Height will not exceed the
Maximum Riser Height.
