The Occurrence tab displays the footing properties that you can edit or that are automatically determined by the software at placement. The property name appears on the left side of the grid and the corresponding property value appears on the right side of the grid. If you selected more than one footing, and then selected the properties command, only the common properties between the selected footings display.
When viewing properties for a single footing, the following properties display. More properties may display depending on what you defined in the reference data. Refer to the Structure Reference Data help for more information on properties.
Category
Select the properties that you want to view for the footing. Footing properties are divided into several different categories: Standard and Weight and CG. You select the category to define values for by using the Category option.
Standard
The standard properties that display depend on the reference data for the footing. Because footing reference data is fully customizable, only the common properties are documented.
Name
Displays the name of the footing. The footing name is based on the Name Rule selection. If you want to type a new name for the footing, in the Name Rule box, select User Defined, and then type a name for the footing in the Name box.
Name Rule
Specify the naming rule that you want to use to name this footing.
-
Default Name Rule - Names the footing using the format "<footing type>-<location>-<index>" where <footing type> is what you select in the Type box on the ribbon, <location> is the global workshare location ID, and <index> is a unique index number that starts at 0001. For example, RectSlabFootingAsm-1-0043.
-
Unique Name Rule - Names the footing using the format "<system>-<footing type>-<location>-<index>" where <system> is the name of the parent system to which the footing belongs, <footing type> is what you select in the Type box on the ribbon, <location> is the global workshare location ID, and <index> is a unique index number that starts at 0001. For example, Structure System-RectSlabFootingAsm-1-0043.
-
User Defined - Select to specify the footing name yourself in the Name box.

Specifies whether or not a grout pad is included between the pier and the member being supported.
Reporting Requirement
Specifies whether or not this footing is reported.
Reporting Type
Select whether the footing is to be tracked by the material control system or not.
Pier Length
Displays or specifies the pier length. If this box is read-only and you want to specify the length yourself, then you need to set Pier Sizing Rule to User Defined.
Pier Width
Displays or specifies the pier width. If this box is read-only and you want to specify the width yourself, then you need to set Pier Sizing Rule to User Defined.
Pier Height
Specifies the distance between the top of the supporting slab and the bottom of the grout (if there is a grout pad) or the bottom of the supported member (if there is no grout pad.)
Pier Shape
Displays the pier shape.
Pier Sizing Rule
Select how you want the size of the pier to be calculated.
-
Select Clearance to have the software size the pier length and width based on either the supported member's cross-section size or the grout size if grout is present plus a clearance value that you specify. The maximum range of the cross-section or grout is automatically calculated and the pier length and pier width values are set using the cross-section range plus the value you specify in Pier Edge Clearance.
-
Select User Defined to specify the pier length and width values yourself.
Pier Orientation
Select whether the pier should be oriented relative to the local coordinate system or the global coordinate system.
Pier Rotation Angle
Specify the rotation angle relative to the north (or y-axis) of the coordinate system selected in Pier Orientation.
Pier Edge Clearance
Specify the distance between the side of the pier and the maximum range of either the supported member's cross-section size or the grout size for that side. This value is used when Pier Sizing Rule is set to Clearance.
Pier Size Increment
Specify the step size to increase the pier length and width dimensions when the software calculates them. For example, if the supported member's cross-section range is 18.25 cm by 23.5 cm and you specify a 1 cm size increment, then the software would round up the pier dimensions to 19 cm by 24 cm. If you were to specify a 0.5 cm size increment, then the pier dimensions would be 18.5 cm by 23.5 cm.
Pier Chamfered
Specifies if the corners of square piers are chamfered or not.
Pier Chamfer Size
Specifies the size of the chamfer if Pier Chamfered is set to yes.
Grout Length
Displays the grout length. If this box is read-only and you want to specify the length yourself, then you need to set Grout Sizing Rule to User Defined.
Grout Width
Displays the grout width. If this box is read-only and you want to specify the width yourself, then you need to set Grout Sizing Rule to User Defined.
Grout Height
Specifies the grout height, which is the distance between the top of the pier and the bottom of the supported member.
Volume
Displays the calculated volume of the footing (including all of the components).
Slab Length
Displays or specifies the slab length. If this box is read-only and you want to specify the length yourself, then you need to set Slab Sizing Rule to User Defined.

Specifies the distance between the bottom of the slab and the bottom of the pier.
Slab Shape
Displays the slab shape.
Slab Sizing Rule
Select how you want the size of the slab to be calculated.
-
Select Clearance to have the software size the slab length and width based on the pier size plus a clearance value that you specify.

-
Select User Defined to specify the slab length and width values yourself.
Slab Orientation
Select whether the slab should be oriented relative to the local coordinate system or the global coordinate system.
Slab Rotation Angle
Specify the rotation angle relative to the north (or y-axis) of the coordinate system selected in Slab Orientation.
Slab Edge Clearance
Specify the distance between the side of the slab and the maximum range of the pier for that side. This value is used when Slab Sizing Rule is set to Clearance.
Slab Size Increment
Specify the step size to increase the slab length and width dimensions when the software calculates them. For example, if the slab is 18.25 cm by 23.5 cm and you specify a 1 cm size increment, then the software would round up the slab dimensions to 19 cm by 24 cm. If you were to specify a 0.5 cm size increment, then the slab dimensions would be 18.5 cm by 23.5 cm.

Grout Rotation Angle
Specify the rotation angle relative to the north (or y-axis) of the coordinate system selected in Grout Orientation.
Grout Edge Clearance
Specify the distance between the side of the grout and the maximum range of the supported member's cross-section for that side. This value is used when Grout Sizing Rule is set to Clearance.
Weight and CG
Displays the center-of-gravity and the weight of the selected object. The center-of-gravity locations are displayed relative to the active coordinate system along the X-, Y-, and Z-axes. The weight value that is displayed in the properties dialog is calculated as the material density multiplied by the object's solid volume. Therefore, the material of the object affects the weight value that is displayed here. Check the material assigned to the object if the weight displayed is an improbable value. For the most accurate weight calculation, use the Tools > Run Reports command.
Dry Weight
Specifies the dry weight of the object.
Dry CG X
Specifies the X-axis location of the dry center-of-gravity.
Dry CG Y
Specifies the Y-axis location of the dry center-of-gravity.

Specifies the Z-axis location of the dry center-of-gravity.
Dry WCG Origin
Specifies the way in which the dry weight center-of-gravity location is defined. The list is defined by the WCGOrigin codelist.
Computed
Indicates that the software calculates the origin location.
Defined
Indicates that you want to manually define the dry weight center-of-gravity location relative to the active coordinate system.
