Based on the steps provided, creating or modifying a "wall property" in Revit typically refers to creating or modifying a specific wall type which possesses various properties, such as structure, materials, and graphical representation. The steps outline a process that involves working with existing wall types, potentially combining them, and adjusting their structural layers and constraints.
Here’s how you can create or modify a wall type in Revit following the outlined steps:
Creating or Modifying Wall Types in Revit (According to the Reference Steps)
The process described focuses on starting with existing wall definitions and modifying or combining them to create a new or adjusted wall type.
1. Load the .RVT Assembly into Your Project
This initial step suggests starting with an existing Revit project file (.RVT) or an assembly that contains predefined wall types or configurations you want to use as a basis.
- Practical Insight: Often, firms or projects use template files (.RTE) or link in standard libraries (.RVT) containing pre-built components, including complex wall assemblies or specific basic wall types. Loading this assembly makes these existing wall types available in your current project.
2. Stack the Two Wall Types Together
This step specifically points to the creation of a Stacked Wall type. A stacked wall combines two or more different basic wall types into a single unit, typically used for foundation walls transitioning to above-grade walls, or different claddings on upper vs. lower portions.
- How to Create a Stacked Wall:
- Go to the Architecture tab > Build panel > Wall dropdown > Wall: Architectural.
- In the Properties palette, select an existing Stacked Wall type from the Type Selector.
- Click Edit Type.
- Click Duplicate to create a new type based on the selected one (give it a unique name).
- Under "Construction," click Edit next to "Structure". This opens the "Edit Assembly" dialog for Stacked Walls.
- Here, you can add, delete, and modify the basic wall types that make up the stack, set their heights (variable or fixed), and align them.
3. Edit Your Wall's Layer Constraints
This step refers to modifying the internal structure and layer properties of a Basic Wall type (either one used within a stacked wall or a standalone basic wall). Wall types are defined by layers of materials, thicknesses, and functions (e.g., Structure, Thermal/Air Layer, Substrate, Finish). Constraints relate to how these layers interact with floors, roofs, and other elements.

How to Edit Basic Wall Structure:
- Select a wall element in your model.
- In the Properties palette, click Edit Type.
- Click Duplicate to create a new type if you are modifying an existing one (give it a unique name).
- Under "Construction," click Edit next to "Structure". This opens the "Edit Assembly" dialog for Basic Walls.
- Here, you can add, delete, move, and modify the layers. For each layer, you define:
- Function (e.g., Structure, Substrate, Finish)
- Material
- Thickness
- Optionally, assign it to the Core Boundary.
- Constraints might involve setting parameters like "Wrapping at Inserts" or how layers join at corners.
-
Example Table: Basic Wall Structure Layers
| Function | Material | Thickness |
|---|---|---|
| Finish 1 | Gypsum Wallboard | 12.5 mm |
| Substrate | Metal Stud Layer | 90 mm |
| Thermal/Air L. | Rigid Insulation | 50 mm |
| Structure | Concrete (Cast-in-P) | 200 mm |
| Finish 2 | Brick, Common | 100 mm |
Note: The "Core Boundary" is crucial as it often defines the structural core that other elements align or join to.
4. Use the "Match Type Properties" Command to Apply the Adjustments to the Adjacent Walls
Once you have created or modified a wall type (either a new stacked wall or an adjusted basic wall with edited layers), you can efficiently apply these new properties to existing walls in your model using the Match Type Properties tool.
- How to Use Match Type Properties:
- Go to the Modify tab > Clipboard panel > Match Type Properties (or use the keyboard shortcut MA).
- Click the wall element that has the desired properties (the type you just created or modified).
- Click the wall element(s) that you want to change to match the first one.
5. Make Further Edits to Your Wall Type
This is a general step for refining the wall type definition. Beyond structure and layer constraints, wall types have many other properties you might adjust:
- Identity Data: Name, description, model, manufacturer, etc.
- Graphics: Coarse scale fill pattern and color.
- Structural: Enable analytical model, structural usage.
- Materials: Specific material assignments for layers (as in step 3).
By following these steps, you effectively create or modify a wall type in Revit, adjusting its definition and then applying those defined "properties" (the type) to elements in your model.
