Top 10 Best Ductwork Design Software of 2026

AutoCAD MEP provides connected duct objects, fittings, equipment, tags, schedules, and annotation tools for mechanical layouts. Duct sizing features support dimensioning workflows, while system definitions and display configurations keep plan, elevation, and documentation views consistent. DWG compatibility benefits firms with established AutoCAD libraries, standards, and production templates.

The main tradeoff is reduced building-information depth compared with Revit-based workflows, especially for model-centric coordination and analysis. Teams producing permit drawings and coordinated DWG packages can work efficiently, while projects requiring extensive Revit MEP families, multidisciplinary model exchange, or IFC export may need additional tools and conversion steps.

Mechanical engineering consultancies gain a connected model for ventilation, heating, cooling, plumbing, and electrical layouts. The ventilation module supports duct geometry, equipment connections, automatic calculations, annotation, and drawing production from shared project data. BIM coordination workflows include IFC export for exchange with external model environments.

The broad module structure increases training requirements and demands consistent libraries, templates, and project administration. Trimble Nova fits large building-services projects where several disciplines must coordinate before construction documents are issued. Smaller duct-only teams may find its wider scope heavier than focused drafting software.

MagiCAD Ventilation provides airflow definition, duct sizing, pressure-loss calculations, system balancing, and detailed reporting across AutoCAD and Revit workflows. Manufacturer-specific components and configurable product data reduce manual recreation of terminals, dampers, fans, and other ventilation elements. Revit MEP families and MagiCAD objects can support coordinated model delivery when project teams maintain consistent content standards.

The broad feature set requires training and disciplined project configuration before calculations and documentation remain consistent across teams. It fits engineering offices delivering large commercial projects that need coordinated layouts, manufacturer content, and calculation reports from the same design environment.

Design Master HVAC focuses on ductwork design outputs used in HVAC projects, with calculations and drawings aimed at sheet metal delivery and review workflows. The tool supports duct sizing and pressure drop style calculations and ties those results to build-ready ductwork layouts and specification-style documentation.

It also targets common coordination needs by generating consistent duct geometry and annotations that can be checked during mechanical coordination meetings. For teams that already work around SMACNA and ASHRAE fitting conventions, the workflow is oriented toward producing repeatable ductwork submittals rather than generic drafting.

Wrightsoft Right-Suite Universal performs ductwork design work by producing sized duct runs from defined layouts and project settings. It integrates sheet metal job output with duct sizing and reporting workflows that duct shops use for takeoff, fabrication-ready documentation, and job tracking.

The Universal edition emphasizes ductwork-specific configuration, fitting loss methods, and construction standard inputs that feed consistent calculations across plans. It also supports CAD interoperability through export and import paths commonly used in mechanical detailing to reduce re-entry of geometry.

FastDUCT is a ductwork design and detailing tool built for generating sheet metal duct systems with repeatable calculations and drawings. It is oriented around duct layout, sizing outputs, and fabrication-ready annotations instead of general HVAC BIM workflows.

Typical work covers duct routing through constraints, deriving dimensions and airside losses for selected sections, and producing documentation for coordination and review. The practical differentiator is how quickly teams can move from duct run definition to consistent build outputs like schedules, takeoffs, and drawing views.

McCormick HVAC Estimating Software focuses on ductwork-oriented takeoff and estimating workflows tied to HVAC project documentation. The software centers around building assemblies, generating labor and material line items, and producing estimate outputs that align with sheet metal execution practices.

It is differentiated by HVAC estimation emphasis rather than CAD-first duct routing, which keeps the workflow efficient for estimating-driven teams that need consistent ductwork calculations. Ductwork detail is handled through estimation inputs and schedules, which can reduce design iteration time when the goal is billable scope definition.

LINEAR Building Solutions centers ductwork design around parameter-driven BIM authoring workflows, with HVAC geometry and documentation built from consistent input rules. It supports CAD to BIM coordination through Revit-ready outputs and structured project data that helps keep routing, sizing, and drawing sets aligned.

The toolchain includes model-to-sheet documentation mechanics and reusable configuration logic that reduces rework during ductwork design review cycles. LINEAR also supports extensibility for project-specific conventions through configurable templates and controlled design parameters used across duct systems.

OpenBuildings Designer generates ductwork designs inside a BIM-centric workflow tied to Bentley’s modeling environment. It supports creating duct geometry that can be coordinated with other building systems through model sharing and discipline separation.

The toolset focuses on specifying and documenting duct runs and fittings using Bentley MEP modeling patterns rather than spreadsheet-only estimating. Integration with Bentley ecosystems is a core differentiator for organizations already standardizing on Revit MEP, DGN-based models, or federated coordination processes.

Elite Ductsize from elitesoft.com targets duct sizing and ductwork design workflows where standard sheet metal sizing rules and project documentation matter. The tool focuses on converting airflow and duct layout inputs into pressure drop outputs and duct sizes while aligning results to common ductwork specification conventions used in practice.

Elite Ductsize is distinct for how it narrows the workflow to duct sizing and design review artifacts instead of broad CAD drafting automation. It fits teams that need repeatable calculation output and consistent duct selection for mechanical coordination deliverables.
