Data Files > SgroupLink.csv
Assembly group links define the connections between metal panels and Assembly Groups in Roof Wizard. These linkages are stored outside the software in a data file that can be modified to customise your material configurations.
🧾 What are assembly group links?
Assembly group links connect specific metal panel product codes to their corresponding Assembly Groups. This system allows the software to automatically apply the correct installation methods, fastening patterns, and material calculations based on the panel type selected.
The linkages are stored in a file called SgroupLink.csv, which maintains the relationship between:
Metal panel product codes
Assembly Group indices (reference numbers)
🔧 File location and structure
The SgroupLink.csv file is located in your Roof Wizard data directory and can be opened with any text editor or Microsoft Excel.
Important: Always create a backup copy before making any modifications to this file.
Component | Description |
Product Code | The unique identifier for each metal panel type in your system |
Assembly Group Index | The numerical reference that links to a specific Assembly Group configuration |
🛠 How to modify assembly group links
Navigate to your Roof Wizard data directory
Create a backup copy of SgroupLink.csv before making changes
Open SgroupLink.csv in a text editor or Microsoft Excel
Locate the product code for the metal panel you want to modify
Update the Assembly Group index to the desired value
Save the file in CSV format
Restart Roof Wizard to apply the changes
⚠️ Important considerations
Care must be taken to use the correct product code from the panel and the index of the Assembly Group. Using incorrect values can result in:
Improper material calculations
Incorrect installation specifications
Software errors or unexpected behaviour
Always verify that both the product code and Assembly Group index exist in your system before making modifications.
💡 Tips for working with SgroupLink.csv
Keep a master backup copy in a separate location
