Round Duct 3D version

HVAC-RD-3D is a software plugin for AutoCAD to create a wide variety of HVAC Round Duct and Fittings in 3D Solids. Also draws flexible duct run-outs to registers. Round duct fittings with Flanges may also be created with a variable gasket gap setting. Each fitting can be placed in Plan, Rise, or Drop views. In the Rise and Drop views an optional elbow fitting can be added at the time of fitting placement.
