Version 6.0 of the commercial duct design software Duct Size has been released. The program is an engineering software program that performs duct design based on the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) 2001Fundamentalshandbook. It displays numerous output reports such as a duct dimension and airflow breakdown report, a material list, a heat loss breakdown report, friction loss breakdown report, and sound-power breakdown report. The user can import a single-line drawing from AutoCad 2004/2005 and export it back to AutoCad as a double-line or 3-D drawing. The entire ASHRAE fitting database of over 200 fittings has been incorporated into the software, including pressure loss data and pictures, the company states. A new feature allows a duct fitting to be suggested based on the current configuration of duct runs.
