Trimble: HVAC design software Trimble MEP The perfect CAD detailing software for sheet metal and HVAC contractors looking to detail duct quickly in an easy-to-use drawing interface. – mep.trimble.com/hvac/design-detailing.

Design Master HVAC is a complete ductwork drafting and calculation software program that works directly inside AutoCAD and BricsCAD. Define the parameters of your project as you draft, then perform calculations within the software using those parameters. Make revisions that are accounted for throughout the design. Build your HVAC systems faster and more accurately with Design Master.

Duct and Diffuser Layout

• Draft intelligent ductwork that responds to changes in your design
• Insert fittings automatically while you draft and modify them as needed
• Draw double-line ductwork as easily as single-line
• Lay out your diffusers and connect them to your ductwork
• Generate a diffuser schedule as you design your project

Adrienne Gould-Choquette, founder of Adicot, Inc, in Sarasota, FL, says that before using our software, “I was spending more time drafting than I was engineering. … Now I have more time to devote to the design.”

CFM and Sizing Calculations

• Size your entire system with a single command, using criteria defined by you
• Make duct-by-duct changes to sizing criteria
• Calculate airflow distribution based upon the building definition and diffusers in your project

Compared to Revit MEP, Senior Project Manager Joshua Lukacs of Design West in San Bernardino, CA, says our software “lets you work far more efficiently – it’s about 50% faster in production.”

Pressure Loss Calculations

Duct Design software, free download

• At the press of a button, calculate pressure drop based upon your drafted layout
• Easily make revisions and recalculate – no data entry required
• Automatically determine the critical path in your system

Duct Design Software Free

“No more manually entering third-party load calculations – now it’s a one-step process,” says Michael Holland, mechanical engineer at Sherlock, Smith & Adams in Montgomery, AL.

Heating and Cooling Load Calculations

• Fully define building location, temperature ranges, materials, and more
• Calculations use rooms that can be drawn directly over your architect’s plans
• Assign and configure zones
• Generate print-ready load calculation reports, ventilation schedules, and psychrometrics based upon your building definition and system layout

“I was instantly converted when I saw how it automatically calculates heating and cooling loads,” says Paul Kenney of Proficient Engineering in Atlanta, GA.

3D Drafting and BIM Compatibility

Ac Duct Design Software

• Generate a full 3D model based upon your 2D layout
• Export to IFC and DWG for use in Navisworks and Revit

Find out why Will Davis, mechanical engineer at MEP Associates’ office in Norman, OK, uses our software “for all the design work I do, including BIM and 3D modeling.”

“I’ve been head of the mechanical departments for several large firms. I think many such companies are missing the boat by not using Design Master.”
