Walls are made from layers of materials that represent the construction materials used to build real walls. In Revit, these layers can be assigned functional values, allowing them to join and react to other layers in the model when walls, floors, and roofs meet. Each wall has at minimum a core, and then you have the option to add additional layers of material to the core to create the wall. These layers can be added inside the core or placed outside the core. As you’ll see, this special wall core layer is a powerful element, and understanding it is essential to mastering Revi
A wall core is much more than a layer of material. The core influences the behavior of the wall and how the wall interacts with other elements in the model such as floors or roofs, etc. Every wall type in Revit has a core material with a boundary on either side of it. These core boundaries are refer- ences in the model that can be snapped and dimensioned to.
What this means is: when you draw a floor above your exterior walls, you will use the pick cre- ation method, select the exterior walls that should define the shape of the floor, and select in the Options bar if you wish the floor to extend only to the Core of the wall, have offset to it, or extend until the end of the wall. This floor creation method will result in a relationship between the floor and the underlying walls such that if those walls change their position, so too will the floor shape and position.
For example, you can constrain a floor sketch to the structural stud layer of walls by using the wall-core boundary to create the sketch (see Figure 5.1). If walls change size or are swapped, the floor sketch maintains its relationship to the core boundary and will auto-adjust.
Note: if you created your floor using the pick method, the locked relationship between the floor and the wall will happen automatically. If you decided to use the draw method instead of the pick method, you will need to manually lock the relationship so that the dependency is established. To get locks to appear, drag sketch lines so that they are co-incident with other lines, or use the align tool. |

| To access and edit wall-core boundaries and material layers, select a wall, go to the Element Properties dialog, click Edit/New to open the Type Properties dialog, and then select the Structure parameter to edit. Doing so opens a new Edit Assembly dialog. Here, you can define materials, move layers in and out of the core boundary, and assign functions to each layer (see Figure 5.2). |
