Finding the right family for specific Revit elements can sometimes be tricky. This article clarifies the family type for Spot Slopes in Revit, offering solutions to help you locate and utilize them effectively in your projects.

Understanding Spot Slopes in Revit

Spot slopes, in the context of architectural and structural design, represent changes in the slope of a surface at a specific point. They are commonly used to indicate subtle grade changes or transitions in terrain modeling, site design, and even roofing. In Revit, these are not represented as individual families in the same way as walls or doors. Instead, their creation and manipulation depend on the underlying surface model.

Where to Find Spot Slope Functionality

Spot slopes aren't housed within a single, dedicated family. Their creation and modification are integral to the families and tools used to create surfaces:

• Topography: If you're working with site grading or terrain modeling, spot slopes are inherently part of the topography surface. Modifying the surface's points directly alters the slopes. You'll manage these through the Topography tool and its associated editing functions. Think of it as directly manipulating the surface data, rather than placing a pre-made "spot slope" component.

• Roofing: For roof design, spot slopes might be implied by the roof geometry. Complex roof forms, created using various roof tools and families, will inherently include slope changes. You'll adjust these slopes through the manipulation of the roof's geometry itself—adjusting the points and lines defining the roof surface.

• Massing Models: Similar to topography, massing models can incorporate slopes. Adjustments to the massing model's geometry will determine the slope at any given point.

Creating Slope Changes: A Practical Example

Let's illustrate how to create a slope change, focusing on a topographic surface:

1. Create a Topography Surface: Begin by creating your topography surface using the Revit Topography tools. Import survey data or manually create points defining the terrain.

2. Edit Points: Select the Edit Points tool within the Topography context. Click on a point on your surface. You can now manipulate the elevation of this point, directly influencing the slope around it. This is where you effectively "create" your spot slope.

3. Observe Changes: As you adjust the point elevation, observe how the surface adjusts and reflects the new slope around that point. This direct manipulation is the equivalent of placing a spot slope.

Key Considerations

• No Specific "Spot Slope" Family: There isn't a specific Revit family categorized as "Spot Slope." The slope is a property of the overall surface.
• Context Matters: The method of manipulating slopes depends heavily on whether you are working with a topographic surface, a roof, or a massing model.
• Underlying Data: Spot slope representation comes down to manipulating the data points that define the surface itself.

By understanding this concept, you can efficiently manage and adjust slopes within your Revit models. Remember to focus on the tools for creating and modifying surfaces to achieve your desired spot slope results. The ability to manage slopes lies within the surface tools themselves, not in a specific family category.
