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 Guide for more information on properties. You can access this document using the Help > Printable Guides command in the software.

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.

  • User Defined - Select to specify the stair name yourself in the Name box.

System

Select the system to which the stair that you are placing belongs.

Horizontal Offset

Specifies the distance between the outside edge of the stair and the selected reference edge or object.

Actual Step Pitch

Displays the actual vertical distance between the stair treads. The software calculates this value using the vertical distance between the top edge and the bottom plane and the stair angle. You can define the maximum allowable pitch between treads in the Step Pitch property.

Reporting Requirements

Specify whether this stair is reported.

Reporting Type

Select the reporting requirements code for the stair. Valid codes are defined in the Catalog task in the Reporting Type select list.

Number of Steps

Displays the number of treads on the stair. This value is calculated by the software and cannot be edited.

Justification

Specifies how the stairs align with the connecting object.

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.

Step Section Angle

Enter the angle, in degrees or radians, by which the step tread's 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.

With Top Landing

Specifies whether the stair includes a top landing.

Top Landing Length

Specifies the length dimension of the top landing for the stairs. Smart 3D only uses this dimension if With Top Landing is set to True.

Platform Thickness

Specifies the thickness dimension for the stair platform.

Post Height

Specifies the height dimension for the hand rail post.

Handrail Post Pitch

Specifies the distance between the handrail posts.

Number of Midrails

Span

Displays the length of the stair stringers. This distance is calculated by the software and cannot be edited.

Height

Displays the vertical distance between the select top edge and the bottom plane.

Length

Displays the length of the stair. This distance is calculated by the software and cannot be edited.

Width

Specifies the width of the stair treads. This dimension does not include the width of the stringers and therefore is less than the overall width of the stairs.

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

Places the stair on the opposite side of the top edge.

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 box 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.
