The workbook is intended to support structured engineering calculations by the purchaser. Its outputs are preliminary or design-support information, subject to verification against project-specific criteria and relevant professional review.
Not Permitted
Redistribution, resale, rebranding and sharing of AIDIA workbooks are not permitted. Purchasing one workbook does not automatically grant broader team redistribution rights.

For engineering support only. AIDIA does not replace professional judgement, laws or regulations, project specifications, design verification or manufacturer/vendor confirmation. Final design decisions remain the responsibility of qualified professionals.

If you need assurance for a specific setup—such as Excel on Windows, macOS, web, mobile or a non-Microsoft application—email the product name and version information to AIDIA support before purchase. No universal compatibility guarantee is made here.
