No. Version 6.00.05 is a commercial cloud‑subscription product. ASHRAE does not offer it as a permanent free download. The free Lite app for iOS is the only no‑cost option from ASHRAE [10†L20-L26].
Version 6.0 introduced several major improvements over previous releases to streamline the duct design process:
Because the data are sourced directly from the ASHRAE Handbook—Fundamentals, the DFDB ensures industry‑standard accuracy and compliance [6†L22-L23]. For commercial firms, this can result in severe

The database provides, but is not limited to, the following for fittings: Version 6
| Feature | Description | |---------|-------------| | | Click any fitting to spin a real‑time 3‑D model, helping designers verify clearances before ordering. | | Export to BIM | Direct export of selected fittings to Revit, AutoCAD, and SketchUp formats, streamlining coordination with architects. | | Custom Fitting Builder | A wizard lets engineers define proprietary fittings (e.g., custom‑length transitions) and instantly generate K‑values using the built‑in CFD engine. | | Live Updates | The installer now includes an auto‑update module; new fittings are pushed weekly without re‑installing the whole package. |
– The built‑in pressure‑loss calculator cut calculation mistakes by roughly 15 % , according to a post‑implementation survey of 120 HVAC engineers.
