Duct Designer is a specialized software tool designed to simplify the complex calculations involved in HVAC duct design and management. The primary function of this application is to accurately calculate the surface area and weight of ductwork components, which are essential parameters for effective planning and installation processes.

Users can input various specifications and dimensions of their duct systems, after which the Duct Designer will perform detailed calculations. These calculations are crucial for determining material requirements and costs, ensuring that projects remain within budget and adhere to specified standards. Once the computations are completed, users have the option to save these results either as individual units or as part of a comprehensive project list, facilitating easy access and reference at any time.

The application further enhances its utility with the capability to generate a summary table for each project or unit. This table provides an overview of the surface area and weight of each component included in the duct system. Such summaries are invaluable for quick reference and for presenting data to stakeholders or clients.

Customization plays a key role in the Duct Designer's functionality. Users can tailor the weight calculation parameters based on specific materials used in their projects, such as galvanized steel or aluminum. The application supports the use of a customizable sheet metal datasheet, which allows users to input specific material properties, ensuring precise weight calculations that reflect real-world conditions accurately.

Additionally, the Duct Designer offers flexibility in terms of dimensional settings. Users can adjust these settings according to their unique project requirements and preferences, providing a high degree of adaptability to meet a wide range of duct design needs.

In conclusion, the Duct Designer is an indispensable tool for professionals working in HVAC and duct design fields. Its accurate calculations, customizable features, and user-friendly interface make it a valuable asset in ensuring efficient and effective project management.
