Wall Instance Properties

Change wall instance properties to modify its location line, base and top constraints, height, and more.

To change instance properties, select the element and change its properties on the Properties palette.

Name Description
Constraints
Location Line A location line for the wall at the specified plane. The wall location line remains the same for that wall, even if the type changes.
Location Line Offset (for walls used as panels only) Offsets the wall panel the specified distance and in a direction perpendicular to the face of the curtain wall.
Base Constraint The base level of the wall. For example, Level 1.
Base Offset The wall's height from its base constraint. This property is available only when the Base Constraint is set to a level.
Base Is Attached Indicates whether the base of the wall is attached to another model component, such as a floor (read-only).
Base Extension Distance The distance you have moved the base of the layers in a wall. See Compound Structure. This parameter is enabled when layers of a wall are extendable.
Top Constraint Wall height extends to the value specified in Unconnected Height.
Unconnected Height The height of the wall when it is sketched, measured upwards from its base.
Top Offset The offset of the wall from the top level. This parameter is enabled only when the Top Constraint is set to a level.
Top is Attached Indicates whether the wall top is attached to another model component, such as a roof or ceiling (read-only).
Top Extension Distance The distance you have moved the top of the layers in a wall. See Compound Structure. This parameter is enabled when layers of a wall are extendable.
Room Bounding If selected, the wall is part of a room boundary. If cleared, the wall is not part of a room boundary. This property is read-only before creating a wall. After you draw the wall, you can select it and then modify this property.
Related to Mass Indicates that the element was created from a mass element. This is a read-only value.
Structural
Structural Usage The structural usage of the wall. This property is read-only before creating a wall. After you draw the wall, you can select it and then modify this property.
Dimensions
Length The length of the wall (read-only).
Area The area of the wall (read-only).
Volume The volume of the wall (read-only).
Identity Data
Comments Specific comments added to describe the wall.
Mark A label applied to a wall. Usually a numeric value. 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.
Categorize as Indicates whether the wall panel should schedule as a curtain panel or a wall.
Phasing
Phase Created The phase when the wall was created.
Phase Demolished The phase when the wall was demolished.
