DUCT PRO 2026

DUCT PRO 2026 for Autodesk Inventor is a specialized HVAC ductwork design add‑in that runs side‑by‑side with Autodesk Inventor, automating the creation of standard sheet metal duct components—rectangular, round, flat oval, fittings (elbows, transitions, tees, offsets), and end flanges. Version 2026 continues the software’s mission of eliminating manual duct modeling by providing an intuitive graphical interface that generates fully parametric Inventor sheet metal parts and assemblies. By leveraging Inventor’s sheet metal environment (flat patterns, bend tables, gauge tables), DUCT PRO significantly increases productivity, reduces modeling errors, and delivers fabrication‑ready output. Whether designing a simple straight plenum or a complex transition/offset network, DUCT PRO ensures that every duct component is accurate, consistent, and ready for CNC cutting and bending.

???? Primary Users

This specialized HVAC sheet metal design software is designed for:

  • HVAC Mechanical Engineers & BIM Modelers creating accurate sheet metal ductwork directly inside Autodesk Inventor.

  • Sheet Metal Fabricators & Detailers generating flat patterns, T-slot/laser-ready DXF files, and duct spool drawings.

  • MEP Contractors & Installers producing shop‑ready duct piece models with hangers and connection flanges.

  • Manufacturing Engineers automating repetitive design tasks and linking duct geometry to CAM (plasma/laser/coil line).

  • Industrial & Commercial Construction Professionals designing ductwork for cleanrooms, hospitals, factories, and data centers.

 

⚡ Key Features & Capabilities

????️ Automated Duct Component Library

Straight Ducts:

  • Rectangular (seam, spiral, welded), round (spiral, lock‑seam), flat oval

  • Length, gauge, corner radius, cross‑break, stiffeners

Fittings (Parametric):

  • Elbows (90°, 45°, 60°, radius, mitered, square‑throat)

  • Transitions (rect‑rect, rect‑round, round‑round)

  • Tees & wyes (straight, reducing, tabulated)

  • Offsets (rectangular, round)

End Flanges & Connections:

  • Flanged ends, TDC/TDF (Transverse Duct Connector / Transverse Duct Flange), angle ring, pocket lock

  • Drive cleat (S‑slip, standing seam, Pittsburgh lock)

  • Flange gasket material (neoprene, closed‑cell foam)

⚙️ Parametric User Interface

DUCT PRO Ribbon:

  • Drop‑downs: component type, material, gauge, connections

  • Live 3D preview (part/assembly) before generation

Data Input:

  • Rectangular: width, height, length, gauge, corner radius
