Creating a Roof Slope Using Slope Arrows

You can use slope arrows to create slopes on a roof. See Creating a Sloped Surface Using a Slope Arrow.

The following example shows a roof that you can create in Revit using a slope arrow.

Creating a Roof with Different Eave Heights

You can create a roof with slope-defined lines at different elevations by joining 2 separate roofs.

Tip: This procedure works best with a multi-level building.
1. Create a footprint roof sketch similar to the following:
   
2. On the Properties palette, specify a cutoff level for the roof. For example, if you are sketching the roof on level 2, you might specify level 4 as the cutoff level.
3. Click (Finish Edit Mode).
4. Create another footprint roof sketch at a higher level, similar to the following:
   
5. Click (Finish Edit Mode).
6. In a 3D view, select both roofs, and click Modify tabGeometry panel (Join/Unjoin Roof).
   
7. View the 2 roofs in a plan view:
   

   You now have a single roof with different eave heights.

Creating a Four-Sided Gable Roof

Use slope arrows to create a 4-sided gable roof.

Note: The results of this procedure will differ from the finished pictures.
1. Create a square footprint sketch and designate all sketch lines as non–slope-defining.
   
2. Click Modify | Create Roof Footprint tabDraw panel (Slope Arrow).
3. On the Properties palette, select New <Sketch> from the filter list.
4. Under Constraints, for Specify, select Slope.
5. Under Dimensions, for Slope, enter 9" (or the metric equivalent).
6. Sketch slope arrows as shown.
   
7. Click (Finish Edit Mode).
8. Open the roof in 3D.
