Introducing Right-CAD®


CAD software for the HVAC Industry- The first all-in-one 3D HVAC solution

Right-CAD® is a powerful fully-integrated residential and commercial 2D/3D CAD solution for HVAC Design. Right-CAD® simplifies the HVAC design process from load calculations to system design (duct, radiant designs, et cetera) to parts take off list and operational costs, among others. Designed at this time to be used as an add-on to Right-Suite® Universal (RSU) licensed modules, users can use either our familiar easy-to-use HVAC shapes or industry-standard CAD commands.  Just like in Right-Suite® Universal, the user can pick the HVAC modules needed for their business and can easily add functionality to meet their business requirements.

MiTek-Wrightsoft’s HVAC Shapes™ are built into Right-CAD®, providing existing Right-Suite® Universal users a familiar way to get going in CAD. Seasoned CAD users will enjoy these smart objects as they streamline the tedious design process and manual data entry, allowing data to be automatically entered by simply dragging and dropping HVAC Shapes™ 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. It’s easy to tilt the 2D floor plan, to see your HVAC design and building in 3D.


Right-CAD® Main Features

Integration with Wrightsoft modules like Right-J®, Right-CommLoad®, Right-D®, Right-CommDuct™, Right-Radiant®, Right-Proposal®, and others.
Use Right-CAD® as the basis to create everything from CAD-quality system designs for an architect, to printable proposals for a customer. (All modules sold separately.*)

Created with both the seasoned CAD user, or non-CAD user in mind.
Right-CAD® will respond to industry standard CAD commands, but also allows non-CAD users to simply use the familiar HVAC Shapes™ in the distinctive RSU ribbon bar, without needing to understand how to use CAD.

Familiar 2D and 3D Interface
Right-CAD® comes equipped with a customizable workspace (including ribbon menus and toolbars) which defaults to mirror the RSU workspace, with which Wrightsoft users are already familiar. This workspace contains all necessary user interface items for HVAC system design, calculations and reports.



Using Legacy dwg Drawings and Extended File Compatibility
Right-CAD® fully supports legacy dwg drawings. Not only does Right-CAD® import and export to RSU, but it also reads and writes dwg files in their native format without any loss of data, from the most advanced file version back to version 2.5. Right-CAD® is a native dwg  file program.

HVAC Shapes and Objects
Right-CAD® features Wrightsoft's easy-to-use HVAC Shapes™, making the transition to Right-CAD® an easy one, for both new and seasoned Wrightsoft users. Right-CAD® replaces tedious line-by-line calculations and manual data entry, allowing data to be automatically entered by simply clicking and drawing with HVAC Shapes™ from a ribbon bar 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.

Program Includes:

Read and write directly to dwg or RSU files
Whether it is added onto your existing RSU platform, or stands on its own, Right-CAD® can both read and write both RSU and dwg files without the use of any other software. This allows complete flexibility with exchanging files, regardless of the end user’s platform.

"Cad-like" menus and commands
Because it was created for both seasoned and novice CAD users, Right-CAD® allows the user to toggle between a CAD-like workspace, and an RSU-like workspace with the simple click of a button.

Multiple ways to view your 2D and 3D designs
Right-CAD® allows to switch your view between plan view and various 2D and 3D Views including 2D Plan View, 3D Wireframe, and 3D Realistic.



View buildings with 3D ducts when paired with additional modules
Use Right-CAD® in conjunction with our other modules to design and view 3D ducts. It can also accurately calculate the heating and cooling loads, sizes the ducts, radiant loop layouts, geothermal and hydronic systems, produce parts takeoff lists, generate proposals based on the parts and prices, and other Wrightsoft modules.*

Import and or create RSU Catalog files with smart HVAC objects
The Catalog is a way to store commonly used drawing blocks and smart objects so that they can be used in multiple drawings. You can create those catalogs from scratch. Additionally, if you have an existing RSU Catalog, it will be automatically imported into Right-CAD® for easy access.

Customizable HVAC templates for  weather data, construction types, libraries and more
Your default template stores your most common settings so when you start a new project, this information is already filled out. This includes contractor information, common weather locations, fuel costs, your libraries and other settings so you can quickly customize any project.

Compatible with all RSU modules, including Right-Energy®
Right-CAD® can license all the standard Wrightsoft® calculation modules and libraries.*

View live changes to your data with Hotlink™ Technology
Right-CAD® 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 repeated data entry, no more mental gymnastics and no more wasted time.*

Training and Support
Right-CAD®, like our other programs comes with various training options as well as a highly skilled technical-support team at your full disposal during regular business hours.

Right-CAD® requires at least one load calculation module like Right-J, Right-F280, Right-CommLoad (ASHRAE RTS) or Right-N to function. Most additional features expressed here will require the addition of at least one of our modules. To see a full list of our available modules, please see the table provided here.

Use Right-CAD to:

Complete room-by-room load calculations and designs in 2D or 3D.

Complete block load calculations 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 insert dwg files into Right-CAD® for calculations from pre-drawn plans. Throw away your scale ruler and simply read or insert dwg files from a builder. Trace floor plans using Right-CAD® HVAC Shapes™ to complete the design, add your notes and send final dwg files to a builder for paperless communication.

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-CAD®, 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-CAD® 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.

Rick Blair Certified Home Energy Rater & Thermographer, Performance Point, LLC says,

"If you're a Wrightsoft user and have been wanting to go to the next level, Right-CAD is it. I'm not conversant with CAD but I was up and running with 3D almost immediately, importing some of my more complex duct designs already created with RSU, and amazed at seeing what I could only imagine before. The 3rd dimension takes the guesswork out of interstitial duct runs, navigating dropped ceiling areas, dropped girders, etc.

Learning curve is simplified by utilizing the familiar tools & tabs already within RSU, and yet with lots of bells and whistles for rainy day exploration and further fine tuning of design presentation. I see this as the future of professional & field ready HVAC design, without the cost and lengthy learning curve of Revit."

Mac owner of Michigan Energy says,

"This company is awesome. The software is pretty easy to use given it's complexity but the real benefit is the service.

Tech support is friendly and patient, the 10 day training course was perfect for a novice user and the trainer was open and understanding - the kind that doesn't make you feel stupid and knows his stuff so well he can explain why the software is doing what it is doing.

A great overall experience!"

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."

Mike Truitt Resnet Rater from This Efficient House says,

“Hands down, the best tool for the job. Our HVAC partners love the 2-line mode drawings, and the export to REM/Rate module saves me at least 2 hours per project! That's a real game changer for us in terms of billable hours and revenue. Mike (sales) and Donald (tech support) have been there for us for over 10 years! Keep up the good work and thanks again guys. - Just another loyal happy customer.”

Jim Heinz President of Heinz Air Conditioning and Heating, Inc. says,

“We are primarily a residential replacement air conditioning and heating company in Clearwater, Florida.  We found a serious issue with improperly sized air conditioning systems in existing homes that was causing issues with humidity, or lack of cooling.  We have used Manual J for over 30 years, but due to the time-consuming process of entering information manually, it was not done unless we had a consumer complaint.  We partnered with Wrightsoft over 15 years ago and can now do a Manual J Load Calculation in less than 30 minutes. Wrightsoft is always there for us, with tech support staff that answers the phone quickly, and offer advice when needed.  There is also a library of how to videos available 24 hours a day on their website. Wrightsoft has continued to be the best option for us for Manual J load calculations.”

Tim Kohut Director of Sustainable Design, National Community Renaissance says,

“I reached out to technical support [to complete an advanced task].  [Technical support] responded within an hour or two, guided me through the process, and even QC’d my spreadsheet (making corrections needed).  I was really impressed… I’ve found that my questions are always answered, usually within hours, and there’s never an attempt to dodge an issue. Wrightsoft’s responsiveness on the support side is what truly sets you apart.  Your team has made my life easier and using RSU has become an integral cornerstone to the work I do guiding our teams in the design and construction of high performance, soon to be ZNE affordable housing.”

Steve Paxton from Air-Dynamics says,

“I've been using Wrightsoft since the late 80’s. Public Service Company in Oklahoma's "Good Cents" program required an ACCA Manual J load calculation and ACCA Manual D duct design to qualify as a "Good Cents" structure. As long as the information is entered correctly, Wrightsoft takes all of the guesswork out of the equation. It has given me peace of mind and keeps our quality of installation above the rest. I can't imagine doing an install without it, it's as important to us as the rest of the tools on our trucks.”

Tom Tumminelli from Brothers Plumbing, Air & Electric says,

“The Wrightsoft experience has been great from the beginning to end.  Their support staff are patient and professional.  Proper equipment sizing is imperative regarding our customers comfort. We have been able to provide our customers with accurate professional data to backup our proposals awarding us multiple projects over our competitors. Well worth the investment of time and money.”
