HVAC-RD-2D is a quick input parametric 2D version plugin for the creation of Round Duct and Fittings.
Any Fitting, any size, any time! also draws flexible duct run-outs to registers. Annotation is automatically added as each fitting is placed.
User controls text height setting for each drawing. 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.
