By default the limit offset is the distance between levels 10 or 4000 mm.
Revit understading roof base offset.
Can be either the host or rails elements.
Then adjust the required offset from these elements.
If you choose rafter the plate offset from base is measured from the inside of the wall.
Modifying revit roof slopes to change the roof from a gable roof to hip roof go into the sketch options select all boundary lines and turn on the defines slope parameter note as a default your roof will have a slope of 30 degrees on all boundaries and form a hip roof unless you change the slope designation in the sketch mode per boundary line.
