See roof boundary line properties.
Revit understading roof base offset.
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.
The parameters above top cut plane and bottom make up the primary range.
To see the effects of this property more clearly set a value for plate offset from base other than 0.
If you choose truss the plate offset from base is measured from the outside of the wall.
In the following section view.
Select the wall and use the attach top base button to attach it to the underside of only the 5 1 2 roof.
To indicate that it should extend upward 4000 mm above level 2 specify an upper limit of level 2 and a limit offset of 4000 mm.
Defines roof slope.
Room 1 has an upper limit of level 1 and a limit offset of 4000.
For footprint roofs specifies a roof line to be a slope defining line.
Then adjust the required offset from these elements.
As you may expect this is the height that revit will cut through elements ie windows doors etc.
You can see that the baluster base is 100mm from the host and baluster top is set to the.
By default the limit offset is the distance between levels 10 or 4000 mm.
Then from the modify tab on your ribbon use the join geometry command and select the 7 1 2 roof and the wall.
In the image below the red dashed line indicate the position of the balusters.
Can be either the host or rails elements.
Set base and top of the balusters.
Creating complex sloping roofs in revit 2014 roof junctions controlling roof slopes and levels.
And element that is on or above this height will be drawn according to it object style.
If you choose rafter the plate offset from base is measured from the inside of the wall.
