Graphical Data Entry


Simplified Designs and Calculations:

Right-Draw® is an easy-to-use data entry tool that simplifies the entire HVAC design process from load calculations and system design to duct and radiant designs and parts takeoff list. View overview video.

Note: This module cannot be used alone. Features listed below are only applicable when used in combination with other modules. Additional information on Right-Draw® can be found within each individual product page.

Main Features:

Right-Draw® replaces tedious line-by-line calculations and manual data entry, allowing data to be automatically entered by simply dragging and dropping HVAC Shapes from a toolbar onto the drawing screen. These smart objects store all of the property information of each shape, making it easy for you to complete your calculation and designs. With the Hotlink Technology, if an aspect of your design or load changes, all the affected components automatically adjust to the new conditions including designs, sizing, and parts take-off lists.

Use Right-Draw® to:

Complete room-by-room load calculations and designs.

Complete block load calculations in quickly and easily. Simply draw a box (or use the room wall-by-wall smart shape tool for complex shapes, add some windows and doors, and adjust your settings.

Draw a room and have 7 aspects of the load automatically entered in the load calculation worksheet. Every wall, ceiling, floor will be entered with infiltration, ventilation, duct loss and gain, and internal gains.

Easily import PDF and AutoCAD files into Right-Draw for calculations from pre-drawn plans. Throw away your scale ruler and simply upload your CAD or PDF file into Right-Draw®, then trace the footprint. Choose to insert, scale and rotate multiple PDF files in the same way as DWG and DXF files, and write layers of your design back to a CAD file, if needed. You can even write back your notes and designs for paperless communication with builders.

Automatically identify adjacent conditioned and unconditioned spaces- even above and below. When drawing any two rooms together (beside, above, or below), this program will automatically identify adjacent spaces and treat them accordingly. For example, adiabatic surfaces (walls, ceilings, and floors between two conditioned spaces) are ignored for load purposes and partitions adjacent to areas designated as unconditioned are calculated accordingly. You can even specify the temperatures or calculate a surface as conditioned during one season and exposed to unconditioned space in the other.

Add an unlimited amount of floors and rooms. This includes unlimited zone capabilities with easy drag and drop zoning and color-coding. In Right-Draw®, each floor of your design is considered a “sheet”. Every sheet is its own layer within the program and can be locked or unlocked, visible or hidden, for ease of use. You may choose to print these sheets directly from the program, which each print out on individual pages.

Tackle irregular rooms. Right-Draw® can handle any room plan, with special tools for vaulted ceilings, dormers, knee-walls, walk-out basements, non-rectangular shapes, and more.

Group items like windows and doors to enter new data, make changes, or just fix mistakes. Choose to select and deselect items, or even select all like-items to make any necessary alterations to their properties, with minimal clicks.

Make global changes to orientation and building properties. Try different “What If?” scenarios for new construction.

Mirror part or all of your design vertically or horizontally. Our mirror function allows you to easily change the layout of the house, without having to completely scrap your work.

Choose to add low and high-velocity duct designs for sizing and radiant floor designs if needed.

Easily handle open to above/below areas.

Add installer instructions, plan review clarification, and other notes and details.

Add custom drawing shapes that automatically add items to a bill of materials.

Right-Draw® links all of the other Right-Suite Universal modules, making it fast and easy to complete load calculations, duct or radiant designs, and more. Thanks to our Hotlink Technology™, any changes you make will automatically update within the worksheet and every module you own- meaning no more data entry, no more mental gymnastics and no more wasted time.


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."
