Residential 2-Line Duct

Right-2Line Duct

CAD-Quality Residential Two-Line Duct Layouts:

Right-2Line Duct removes the single line that represents the trunks, branches and fittings of your duct design in the Right-Draw® screen and replaces it with accurately scaled two-line duct systems, resulting in CAD-quality designs. View overview video.


Right-2Line Duct turns your simple duct design into a professional looking CAD quality file in just the click of a button.

Use Right-2Line™ Duct to:

Easily view both single-line, two-line and combination branch designs. This program allows you to easily toggle between one and two-line branch designs for ease of use during the design process. The user may also choose to mix both two-line and one-line branch designs.

Write two-line plans back to a CAD file. Right-2Line Duct offers the ability to write your duct design back to that CAD file as layers. (Writes to AutoCAD DWG and DXF files when CAD file is imported.)

Adjust which side trunks reduce.

Right-2Line Duct separates you from the competition by making any drawing look professional with the click of a button. Builders can then seamlessly access these plans, creating a professional line of communication and a paperless office. Additionally, increasing clarity of the design plan can help to reduce installer mistakes and help a designer to better visualize their design within the space. 


Roquey from Integrity Comfort Solutions says,

"I have used Wrightsoft since the days of monochromatic screens and the spreadsheet-only format. I've attended several classes, been to the World Headquarters in Lexington, and even hosted training classes. The level of support is phenomenal. Both in the classroom, call in and email.

I've used the Right J, Right Draw modules extensively in the new construction markets not only for the purpose intended, but also to "value engineer" the materials selection process for my clients. I can't imagine a better product. The learning curve is pronounced and requires commitment on the part of the user, but with constant use it becomes almost second nature.

As a 40+ year veteran of our industry, I highly recommend this company."

Mike Douglas, from Advent Air Conditioning says,

"As a business owner, one of the things I like is that Right-Draw gives us a level of professionalism whether it’s a specialty home or a basic starter home. Within the past year, we have actually picked up new accounts because our customers were so impressed by the professionalism of our designs, particularly when we go up against contractors who are giving them what amounts to a crayon rendition on a napkin."

Bob Pietrangelo from Comfort Solution says,

"I’ve always been a proponent of proper sizing of air conditioning equipment. For a standard 3,000 square foot, 4 bedroom house, doing the load calculations manually would take many hours. Then I found Wrightsoft, and by using their Right-J and Right-D, I was able to produce load calculations and duct design in about an hour."

Al Gagne from Bayside Mechanical says,

On our Training:
"I've been to three of your trainings over the last 7 years and every time I go I learn something new. The class provides a thorough understanding of Right-Suite® Universal and helpful shortcuts so that I can continue to run my business effectively in this changing market."

On our Software:
"Wrightsoft’s Right-Suite® Universal has helped us to turn bids around faster, especially for custom home builders. I can simply import the AutoCAD building plans as a layer in the program, trace to complete the load calculations and add my ducts to the design, saving me a considerable amount of time. The full design and calculation is then saved in the AutoCAD file as another layer."
