Start and End Points for Extruded Roofs
The extrusion of a roof can extend in either direction along the plane perpendicular to the face of a solid
component (such as a wall). If the extrusion extends away from the solid, the start and end points are positive
values. If the extrusion extends toward a solid component, the start and end points are negative.
You can edit the start and end points through the roof properties. See
Roof Properties
on page 635 for more
information.
Adding Sloped Glazing
You can create sloped glazing using the footprint or extrusion method. Sloped glazing has one or more
slope-defining lines and can join to curtain walls and basic wall types.
Sketching Sloped Glazing
1
On the Modelling tab of the Design Bar, click Roof
➤
Roof by Footprint or Roof by Extrusion.
NOTE
If you try to create a roof on the lowest level, a dialog prompts you to move it to a different
level, ensuring that the roof is higher than any walls joining to it. If you choose not to move the roof
to a different level, Revit Architecture notifies you later if the roof is too low.
2
Sketch the roof.
3
If the roof is based on a footprint, specify roof boundary lines as slope-defining, or use the roof
slope arrow to define the slope. See
Roof Slope Arrow
on page 616.
4
On the Design Bar, click Finish Sketch.
5
Select the roof, and, in the Type Selector, select Sloped Glazing.
You can place curtain grids on the curtain panels of the sloped glazing. Press
TAB
to switch between horizontal
and vertical grids.

Joining and Unjoining Roofs
Use the Join/Unjoin Roof command to join roofs to other roofs or walls, or to unjoin them if they were
previously joined. The command is especially useful if you have already sketched roofs and walls and then
want to change your design by adding smaller roofs to create dormers or awnings.
