New Features

• The Duct Size 6.0 software has been entirely re-written to take advantage of the latest programming and back-end database technologies. In addition, the entire ASHRAE fitting database of over 200 fittings has been incorporated into the software, including pressure loss data and pictures.
• A new and improved user interface (UI) has been designed making the input process much faster and more intuitive than previously. This improved UI includes a tree-like navigation area that allows the user to view all duct systems, fans, and duct nodes.
• Within the navigation area, basic information such as airflow, dimensions can be displayed next to each duct node allowing the user to quickly view important information about the entire duct system.
• The user can copy duct systems within the same project and also copy sections of duct nodes within the same duct system.
• The user can easily replicate entire projects so as to reuse common information.
• An unlimited number of duct system templates can now be created so that the user can create new duct systems using common data from the templates.
• Includes new "Suggest a fitting" technology that allows Duct Size to suggest a duct fitting based upon the current configuration of duct runs
• Can model duct systems based upon the constant velocity method of calculations
• Input checks have been incorporated so the user can confirm that inputs are valid prior to calculating.
• Includes many more reports including addtional sound-power and attenuation reports.
• All input and output data can be exported to Microsoft Word and Excel templates.
• Reports can be exported to XML format so that they can be shared with others across networks and operating systems other than Windows.
• Can import from AutoCad 2004/2005 DXF files
• Can export to AutoCad 2004/2005 DXF files
• Can import and export information from AutoCad Building Systems
• An additional 300 cities have been added to the weather database making the total 800.
• . . . and more.
