Once you have created a duct system, you can analyze the system design to determine the optimal sizes for system components. You export system data from the drawing and analyze it using an external software tool. Once the data has been analyzed, and optimal sizes have been calculated for system components, you then import the calculated data into your drawing and resize the system. Trane
VariTrane™ Duct Designer and Elite Duct size are 2 applications that can analyze and size duct systems in AutoCAD MEP 2023 toolset drawings.
Duct system data is exported and imported in Duct Design Extensible Markup Language (DDXML). DDXML is a schema used to store and transfer data for duct networks. It can be used directly in duct analysis packages.
