Design Master HVAC is a comprehensive add-in for AutoCAD and BricsCAD, designed to automate and streamline HVAC system design, drafting, and engineering calculations. The software enables users to lay out ductwork directly within CAD drawings, perform integrated heating and cooling load calculations, and automatically size ducts and calculate pressure losses. It supports 3D drafting and BIM compatibility, allowing for the export of models to formats suitable for collision detection and further coordination in platforms like Revit and Navisworks. The tool centralizes all HVAC design data within the CAD environment, reducing manual data entry and improving design accuracy and efficiency for both residential and commercial projects.

Key Features

Ductwork Drafting and Layout Enables intuitive ductwork design directly in AutoCAD or BricsCAD.

• Focus on overall system layout without constant data entry.
• Supports both 2D and 3D drafting.

Integrated Load Calculations Performs heating and cooling load calculations within the CAD environment.

• Uses building geometry and room properties from the drawing.
• Adjusts calculations automatically as the design changes.

Automatic Duct Sizing and CFM Calculations Calculates duct sizes and airflow (CFM) based on diffuser settings and sizing methods.

• Reduces manual calculation errors.
• Updates automatically with design modifications.

Pressure Loss Calculations Calculates pressure drop for each duct section using CFM, duct shape, length, and fittings.

• Ensures accurate system performance analysis.
• Supports compliance with engineering standards.

3D Drafting and BIM Compatibility Generates 3D models of ductwork and equipment for BIM workflows.

• Exports to IFC or DWG for use in Revit, Navisworks, and SketchUp.
• Facilitates collision detection and coordination.

Customizable Equipment Schedules and Documentation Creates detailed equipment schedules and project documentation.

• Supports custom schedules for various HVAC components.
• Generates print-ready reports and visual load calculation maps.
