Wall Type Properties

To modify a type property of a wall, you change the value of the corresponding parameter as described under Modifying Type Properties.

Note: Changing a wall type property will affect all walls of that type in the project. Note also that the type name does not update when you change type parameter values. For example, you could use the type parameter Structure to change the width of the Generic - 6” wall type to 6.5”, but the type name will remain Generic - 6”. If you want to create a new wall type, click Duplicate. For more information, see Creating a New Family Type in a Project.

Common type properties for walls are described below.

Name	Description
Construction
Structure	Click Edit to create compound walls. See Compound Structure.
Wrapping at Inserts	Sets the layer wrapping of walls at inserts. See Layer Wrapping.
Wrapping at Ends	Sets the layer wrapping of wall end caps. See Setting Layer Wrapping.
Width	Sets the width of the wall.
Function	Categorizes the wall as Exterior, Interior, Retaining, Foundation, Soffit, or Core-shaft. Function is used in scheduling and to create filters that simplify a model for visibility or when exporting. Wall function is also used when creating a gbXML export. (See Function of Walls Floors and Building Pads.)
Graphics
Coarse Scale Fill Pattern	Sets a fill pattern for a wall in a coarse-scale view. See View Properties.
Coarse Scale Fill Color	Applies a color to the fill pattern for a wall in a coarse-scale view.
Identity Data
Model	Generally, this is not an applicable property for walls.
Manufacturer	Generally, this is not an applicable property for walls.
Type Comments	A field for placing general comments about the wall type.
URL	Link to a web page.
Description	Description of the wall.
Assembly Description	Description of the assembly based on the assembly code selection.
Assembly Code	Uniformat assembly code selected from hierarchical list.
Type Mark	A value to designate the particular wall. Generally, this is not an applicable property for walls. This value must be unique for each wall in a project. Revit warns you if the number is already used but allows you to continue using it. You can see the warning using the Review Warnings tool. See Reviewing Warning Messages.
Fire Rating	Fire rating of the wall.
Cost	Cost of the materials for constructing the wall.
Analytical Properties
Heat Transfer Coefficient (U)	Used in calculating the heat transfer, typically by convection or phase change between a fluid and a solid.
Thermal Resistance (R)	A measure of a temperature difference, by which an object, or material, resist a heat flow (heat per time unit or thermal resistance.
Absorptance	A measure of the ability of an object to absorb radiation, equal to the ratio of the absorbed radiant flux to the incident flux.
Roughness	A measure of the texture of a surface.
