Assign Layers Tool
When editing vertically compound walls , the Assign Layers tool assigns a row to a layer or region. (It assigns
the number, material, and function of that row.)
It is more useful to assign layers to regions vertically, rather than horizontally. For example, you might split
finish layer 1 into several regions. Then you could assign another finish row to some of those regions and
create an alternating pattern, such as brick over concrete.
You should familiarize yourself with the layer functions of compound walls. See Applying a Function to a
Layer of a Compound Structure on page 813. Also see Layer Assignment Rules on page 644.
To assign wall layers:
1 Click a row number to select it.
All regions currently assigned to that row appear selected in the preview pane.
NOTE If the row does not have any regions assigned to it, it appears as a line in the preview pane,
and its thickness is 0.
2 Click Assign Layers.
3 Highlight a region boundary.
4 Click the boundary to assign the row to that region.
5 Continue clicking other regions to continue assigning, or click Assign Layers to exit.
Layer Assignment Rules
When assigning layers in walls, consider the following guidelines:
■ Rows of the sample wall in the preview pane must remain in a sequential order from left to right. To test
the sample wall, select row numbers sequentially and observe the selection in the preview pane. If the
layers do not highlight in an order from left to right, Revit Architecture cannot produce this wall.
■ A row cannot be assigned more than one layer.
■ You cannot have the same row assigned to regions on both sides of the core.
■ You cannot apply a thickness to a membrane layer.
■ Non-membrane layers cannot have a thickness smaller than 1/8" or 4 mm.
■ A layer in the core must have a thickness greater than 0. You cannot specify a layer in the core as a
membrane layer.
■ The exterior and interior core boundaries and the membrane layer cannot rise up and down.
