# How to update the Lookup Engineering to use my own engineering data? In this video, we guide you through editing and modifying the preliminary engineering library in Shedmate. Learn how to upload and manage historical data and engineering computations for efficient quoting. We demonstrate using the engineering analysis system to check site-specific wind forces, structural loads, and adjust frames in real-time. Detailed instructions on updating your engineering library using Excel are provided. Remember, while Shedmate speeds up preliminary engineering assumptions, final approvals must be obtained from a licensed structural engineer. Reach out to support for further assistance. DISCLAIMER: The Shedmate Lookup Engineering feature is designed to assist companies in expediting preliminary engineering assumptions for quotation purposes. If you are not using our PAYG Engineering Services, Shedmate assumes no liability for any engineering reports or designs produced using our system. It is essential that all engineering calculations, designs, and reports are independently reviewed, signed, and approved by a licensed structural engineer. Users are responsible for ensuring compliance with all relevant engineering standards and regulations. {% embed url="" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
