Wall Type Properties

Change wall type properties to modify its structure, wrapping behavior, function, and more.

To change type properties, select an element and click Modify tabProperties panel (Type Properties). Changes to type properties apply to all instances in the project.

Name	Description
Construction
Structure	Click Edit to create compound walls. See Compound Structure.
Wrapping at Inserts	Select either Do no wrap (default), Exterior, Interior, or Both. Sets the layer wrapping of walls at inserts. See Layer Wrapping. Note: Wrapping is not supported for walls with a tapered cross section.
Wrapping at Ends	Select either None, Exterior, or Interior. Sets the layer wrapping of wall end caps. See Layer Wrapping. Note: Wrapping is not supported for walls with a tapered cross section.
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 About the Function of Walls, Floors, and Building Pads for gbXML Export.)
Cross Section Properties (Wall structure must have variable layer)
Default Exterior Angle	Angle (from vertical) of the exterior wall face. Value can be overridden in the wall instance properties.
Default Interior Angle	Angle (from vertical) of the interior wall face. Value can be overridden in the wall instance properties.
Width Measured At	The position where the total width of the wall is measured.
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.
