Vertically Stacked Walls; Defining The Stacked Wall Structure - Autodesk 256B1-05A761-1301 - AutoCAD Revit Structure Suite 2010 User Manual

Vertically Stacked Walls

Revit Architecture features a stacked wall type which is one wall that includes several different subwalls
stacked on top of each other. All subwalls in a stacked wall are attached and have joined geometry to each
other; the subwalls can only be types in the Basic Wall system family. For example, you can have a stacked
wall comprising an Exterior Brick on Metal Stud and an Exterior CMU on Metal Stud that are attached and
joined.
Using stacked wall types, you can define different wall thicknesses at different heights. You define its structure
using Type Properties.
Specifying Instance Parameters of Subwalls
When you define the structure of the stacked wall type, you indirectly change instance parameters of the
individual subwalls that compose the stacked wall. That is, when you specify the height, offset, top, and
base of the stacked wall, you are also specifying Unconnected Height, Location Line Offset, Top Extension
Distance, and Base Extension Distance, respectively, of the subwalls. The only instance parameters you can
directly specify for subwalls are Room Bounding and Structural Usage; values for the remainder are inherited
from the stacked wall type and are read-only.

Defining the Stacked Wall Structure

You can make various changes to a stacked wall to change its structure:
You can add or delete walls.
You can move subwalls up or down the height of the stacked wall.
You can define a reference line for the entire stacked wall, and then offset each subwall from that reference
line.
IMPORTANT Define the structure of vertically stacked walls before placing any instances in the project. Height
conflicts may occur when previously placed instances are lower than the defined height of the type.
