1. Purpose of the feature
The Leg Loads by Selected Bay feature simplifies the process of calculating dead and live loads applied to the bay legs for a modular scaffold system. By using this feature, you can easily select a bay within the model, which has been added using the Bay tool.
Additionally, any components that are added to the bay via the Item tool will automatically be included in the load calculations, ensuring accurate and comprehensive results.
Prerequisites
Microsoft Excel must be installed on the machine prior reports generation.
2. User Interface overview.
The tool is located under the Engineering tab.

To open the tool menu please double click on the tool.
The "Leg Loads by Bay" function may be preselected in the Report Type row (under number 4) as shown below.
Take a moment to familiarize yourself with the interface:

File Name and Naming Components in Reports |
The File Name is a view-only value generated automatically based on the following structure: Prefix: A customizable text field that can be filled by the user. If provided, it will appear at the beginning of the report name and be included in the File Name. |
![]() |
Checkbox options |
Include Job Number: When selected, the job number from the Project Info will be added to the file name. Include System: When selected, the system name will be included in the file name. Include Selection Box Name: When selected, the name of the selection box will be added to the file name. |

Revision
|
The "Revision" field allows the user to enter a custom Revision text value to be displayed at the end of the specified report name and will also be included in the file name. |

The "Report Type" is a drop-down list that offers the following available report options:
Show numbering – when selected, the model view will be updated to display existing engineering selection box names and wall tie numbers. Deselecting this option will remove these elements and update the view model accordingly. |

The following fields require user input and are used in the Live Load calculations on the Leg Load tab under the Live Load section: Main Platform – Max UDL: Consoles – Max UDL: Number of Lifts Loaded (Main Platforms): Number of Lifts Loaded (Consoles): These inputs are essential for accurate Live Load calculations and should be filled out thoughtfully. |

Engineering Selection Box Settings: New Box Name: Enter a text value that will be assigned as the name for a newly inserted engineering selection box. Show Ratio Per Selection Box: When selected, the ratio values will be displayed in the model once the engineering selection box is calculated (after clicking the "Get Data" button). A component ratio represents the component mass to be included into the dead load calculations. As an example, 0.5 ratio of the component represent half of the component mass to be included into the dead load calculations. These values will disappear when the view is updated or redrawn.

Standard location |
The dropdown list displays the four available standard locations. When a location is selected, the corresponding engineering selection box will be highlighted in the model and calculation results displayed in the dead and live load tables for the leg selected. The available locations are:

Dead load data grid |
This data grid summarizes the dead load for structural analysis of a leg selected in the Standard location (as above in 7) . Helps to preview material weights and overall structural loads for project planning or safety assessments. Components are grouped by type (e.g., Base Collar, Base Plate 60), with details like unit mass, selected quantity, and total mass. Down the bottom there is a summary of Total mass of components captured by the selection box (per leg selected in the Standard location (as above in 6). Total dead load of components captured by the selection box (per leg selected in the Standard location (as above in 6). |

Live load data grid |
The table ensures accurate live load assessment for a selected leg (as set in the Standard location as above in 6) by considering factors like platform area, load distribution, and selection ratio. This allows designers and engineers to ensure the scaffold meets safety and stability requirements. ![]() Example: Imposed Load:
