Minimum Footing Cover
|
For Back facing, this parameter determines the height above the
footing the Elev at Face is calculated to if no Elev At Face elevation target
is set.
|
Numeric
|

Target parameters
This section lists the parameters in this subassembly that
can be mapped to one or more target objects, such as a surface, alignment, or profile
object in a drawing. For more information, see in the AutoCAD Civil 3D User’s
Guide Help.
|
Parameter
|
Description
|
Status
|
|
Wall Height
|
Is used to determine the footing dimensions. A profile needs to be created
which reflects the Design Wall Height. For instance if the wall height is 4,
then the profile elevation for the Wall Height would need to be 4.
|
Optional
|
|
Top of Footing
|
Used to control the elevation the top of footing is placed at.
|
Optional
|
|
Top of Wall
|
For Face Attachment, used to locate the top of wall elevation.
|
Optional
|
|
Elev at Face
|
For Back Attachment, used to override the minimum footing cover
value.
|
Optional
|
Output Parameters
None.
Behavior
This subassembly is intended to provide a way to model a
B3-3 Caltrans Retaining Wall. The subassembly may be inserted either on the
Face of the retaining wall (exposed side) or the Back of the Retaining wall
(side covered by the soil being retained). The dimensions of the footing are
taken from the Wall Height Elevation Target which should reflect the Design
Height of the retaining wall.
Layout Mode
Operation
In layout mode the subassembly draws the retaining wall
based on internal code. There is no way to adjust the dimensions.
