Turn on
Lowered to create a lowered eaves soffit. Turn
on
Lowered and enter a value in the left and
right
Lowered text fields to represent the distance
from the truss’ ‘zero’ level to the underside of the overhang.
Note: If the Lowered value is too small, a red circle displays below the Lowered text fields. Red circles indicate an invalid structural engineering truss design. By entering a higher value in the Lowered text fields, the overhang results in a valid solution and green circles display. Green circles indicate valid Lowered values.
