- About Roofs
Revit LT offers several methods of creating roofs. Choose the method that best meets the needs of your design. - About Start and End Points for Extruded Roofs
The extrusion of a roof can extend in either a positive or a negative direction along the plane perpendicular to the face of a solid component (such as a wall). - Create a Roof by Footprint
Creates a roof using the building footprint to define its boundaries. - Create a Roof by Extrusion
Creates a roof by extruding a profile that you sketch. - Modify a Roof
After creating a roof, you can change its shape or overhang, cut openings, or align ridges. - Join Roofs
You can join roofs to other roofs or walls, or unjoin them if they were previously joined. - Roof Slope
You can define the slope of a roof using various methods. - Eaves
When creating a roof, specify an overhang value to create eaves. After completing the roof, you can align eaves and change their cut and height. - Fascia
You can add fascia to edges of roofs, soffits, and other fascia. You can also add fascia to model lines. - Soffits
Use the Roof Soffit tool to model the underside of a building element. - Gutters
You can add gutters to edges of roofs, soffits, and fascia. You can also add gutters to model lines. - Dormers
Create dormers to enhance and expand a roof. - Roof Boundary Line Properties
When editing the roof footprint, change properties of a roof boundary line to define its slope, overhang, offset, and more. - Roof Instance Properties
Modify instance properties to change an individual roof's work plane, base level, slope, and more. - Roof Type Properties
Modify type properties to change a roof family's structure, fill pattern, and more. - Revit LT Roof Sample File
