The Occurrence tab displays the stair properties that you can edit or that are automatically determined by the software at placement. The property name displays 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 stair, and then selected the properties command, only the common properties between the selected stairs display.
When you view properties for a single stair, the following properties display. More properties may display depending on what you defined in the reference data. Refer to the Structure Reference Data for more information on properties.
Category
Select the properties that you want to view for the stair. Stair properties are divided into several different categories: Standard, Weight and CG, Fabrication and Construction, Surface Treatment and Coating, and Responsibility. You select the category for which you want to define values by using the Category option.
Standard
The standard properties that display depend on the reference data for the stair. Because stair reference data is fully customizable, only the common properties are documented.
Name
Displays the name of the stair. The stair name is based on the Name Rule selection. If you want to type a new name for the stair, select User Defined in the Name Rule box, and then type a name for the stair in the Name box.
Name Rule
Specify the naming rule to use to name this stair.
-
Default Name Rule - Names the stairs using the format "<stair type>-<location>-<index>" where <stair 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, StairA1-1-0043.
-
Unique Name Rule - Names the stairs using the format "<system>-<stair type>-<location>-<index>" where <system> is the name of the parent system to which the stairs belong, <stair 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-StairA1-1-0043.

Side Frame Section Cardinal Point
Specifies the relative position of the structural cross-section to the member placement line. Nine cardinal positions (1-9) are available. The location of cardinal points 10 (center-of-gravity) and 15 (shear center) depend on the section shape. The local z-axis of the member and the center-of-gravity point of the section define cardinal points 11 and 14. The local y-axis of the member and the center-of-gravity point of the section define cardinal points 12 and 13. Cardinal points 10 through 15 are unavailable for designed members or cans.
Side Frame Section Angle
Specifies the angle, in degrees or radians, by which the side frame cross-section rotates about the member axis. The zero-degree position is either the global Z-axis or the global X-axis, depending on the member orientation.
Handrail Section Cardinal Point
Specifies the relative position of the structural cross-section to the member placement line. Nine cardinal positions (1-9) are available. The location of cardinal points 10 (center-of-gravity) and 15 (shear center) depend on the section shape. The local z-axis of the member and the center-of-gravity point of the section define cardinal points 11 and 14. The local y-axis of the member and the center-of-gravity point of the section define cardinal points 12 and 13. Cardinal points 10 through 15 are unavailable for designed members or cans.
Handrail Section Angle
Specifies the angle, in degrees or radians, by which the handrail cross-section rotates about the member axis. The zero-degree position is either the global Z-axis or the global X-axis, depending on the member orientation.
Step Section Cardinal Point
Specifies the relative position of the structural cross-section to the member placement line. Nine cardinal positions (1-9) are available. The location of cardinal points 10 (center-of-gravity) and 15 (shear center) depend on the section shape. The local z-axis of the member and the center-of-gravity point of the section define cardinal points 11 and 14. The local y-axis of the member and the center-of-gravity point of the section define cardinal points 12 and 13. Cardinal points 10 through 15 are unavailable for designed members or cans.

Angle
Specifies the angle of inclination between the selected bottom plane and the stair stringers.
Step Pitch
Specifies the maximum allowable vertical distance between the stair treads. The actual distance is calculated by the software using the vertical distance between the top edge and the bottom plane and the stair angle. The actual distance is displayed in Actual Step Pitch.
Side

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.
