Duct Size 6.0:

The following is a list of features available in Duct Size 6.0:

The Duct Size 6.0 software is a stand-alone program. However, it also works with AutoCad. The user can import a single-line drawing from AutoCad and export it back as a double-line or 3-D drawing.The purpose of this software is to provide the user with a total duct system analysis so that they can properly size the duct work and the fan that serves the duct system. This program is geared specifically toward the HVAC engineer, architect, design/build mechanical contractor, and building maintenance supervisor.

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 ofduct 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 ductfitting 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 validprior 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 acrossnetworks 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.
