the wall display in the preview pane.
The preview pane displays the wall in section view.
A table shows the different wall types that compose the stacked wall. Every stacked wall has at
least one subwall in it.
This establishes an imaginary reference line to align all the subwalls of the stacked wall. For
example, if you select Finish Face Exterior, each subwall piece aligns to its finish face. This value
becomes the Location Line value of each subwall.
This is the height of the wall in the preview pane. This value changes when you insert subwalls
whose unconnected height is greater than the sample height.
to the main wall.
NOTE One subwall is required to have a variable height. Its height changes relative to the heights
of the other subwalls. You cannot edit the Height field when the subwall is variable. To change the
height of the variable subwall, change another subwall to variable by selecting its row and clicking
Variable.
of the subwall from the reference line (Offset) of the main wall.
A positive value moves the subwall toward the exterior side (left side in the preview pane) of
the main wall. For example, if the reference line of the main wall is set to Wall Centerline, and
you specify 1'' for all subwall offsets, each subwall is aligned 1'' to the left of the centerline of
the main wall.
This value raises or lowers a wall layer that is unlocked at the top or bottom. A positive value
moves the layer up; a negative value moves it down. This value corresponds to the value for the
Top or Base Extension Distance instance parameters for the subwalls. For more information on
unlocking layers, see Vertically Compound Walls
If you specify an extension distance for a subwall, the subwall below it attaches to it. For example,
suppose you specify a Base Extension Distance of 2 feet for the top subwall. The top of the next
subwall down moves up to attach to the modified wall above it. The value for Top Extension
Distance of the lower subwall is Attach. For example, in the following image, the top wall is
highlighted in red. It has a positive base extension distance. The lower subwall attaches to it.
