NOTE If you try to add a roof on the lowest level, a dialog prompts you to move it to a higher level.
If you choose not to move the roof to a different level, Revit Architecture notifies you later if the roof
is too low.
3 On the Design Bar, click Lines or Pick Walls, and sketch a closed loop for the roof.
To edit roof properties before sketching it, on the Design Bar, click Roof Properties.
TIP When using Pick Walls, you can specify the overhang before you sketch the roof. On the Options
Bar, select Extend to wall if you want the overhang to be measured from the core of the wall, and
then specify a value for Overhang.
4 Set slope defining lines.
To change the slope definition of a line, select the line and, on the Options Bar, click the Defines
Slope check box. For lines that are slope defining, you can change the slope value by clicking
the line and editing the value.
When a roof line is set to slope defining, this symbol appears adjacent to it . In the following
image, the top horizontal line and the bottom horizontal line are slope defining.
5 On the Design Bar, click Finish Roof.
To see the roof, open a 3D view.

Footprint Roof Tips
■
To cut off a roof in order to sketch another roof on top of it, use the Cutoff Level constraint in the Element
Properties dialog, and then specify a height for the Cutoff Offset. This property specifies the distance
above or below the level at which the roof is cut off.
■ If a roof includes a slope-defining arc line, you can specify the number of segments for the line. In the
Element Properties dialog, specify a value for Number of Full Segments. By default, 4 segments are created.
If you specify zero segments, a conical roof is created.
