Design Master Electrical RT

Digitally signed app



Design Master Electrical RT expands the electrical design features in Autodesk® Revit®.


One-Line Riser Diagrams: Create a one-line riser diagram in a drafting view that is linked to your Revit model. Customize the graphics to match your current one-line diagram style. Keep your one-line diagram synchronized with the rest of your project as your design changes.


Feeder Sizing: Size feeders automatically based upon the upstream overcurrent protection for a piece of electrical equipment. You have complete control of the chosen feeder size and can override it when necessary.  


Branch Circuit Sizing: Size branch circuit breakers and wire sizes automatically based upon the connected load. You have complete control of the breaker and wire size and can override it when necessary.


Fault Calculations: Calculate available fault current for each piece of electrical equipment. The calculated fault current can be used to set the AIC rating for the device. 


Voltage Drop Calculations: Calculate voltage drop between each piece of electrical equipment. Feeders that exceed the maximum 3% voltage drop allowed can be easily resized. 


Arc-Flash Calculations: Calculate arc-flash at each piece of electrical equipment. An arc-flash schedule can be created that displays the calculated values. Arc-flash warning labels can be printed to be put on devices in the field.


Selective Coordination: Assign time-current curves to breakers in your project. Display the time-current curves on a drafting view for selective coordination.


Design Master Electrical RT is available for purchase on our website for $400 / year. 


Note: This app uses a custom installer (and not the standard App Store installer).

  • The Best Thing That Ever Happened to Revit for EE's
    Katherine McKeever | August 02, 2021

    I'm hooked and I don't ever want to design without it. 

  • Design Master Makes Revit Usable in The Design Build Market
    Robert Wilson | July 30, 2021

    With learning about Design Mastgers calculating load ability and being able to get everything connected together made the design process really easy, then with making the switch to Revit and finding out that Revit could not do the very basic things that Design Master would left you wondering if the switch was worth it even though the 3D drawing process was much easier in Revit. As Design Master started to to evolve towards Revit you could start to see the great parts of both programs coming together to make the design process getting as easy in Revit as it was in AutoCAD, but you get the ability to get all schedules being updated as you make changes, no more having to wait on everything to do recals on every change.

  • Making Revit work for You
    Mark Kostroun | July 12, 2020 Verified Download (What's this?)


    Design Master Electrical RT takes all the things you would expect Revit to do and actually does them. Sophisticated feeder sizing, breaker sizing, short circuit calculations, dynamic circuit descriptions, one lines, etc. Before Electrical RT it was frustrating to have all this information in the model but not being used by Revit to automate tedious tasks.

    A must have for anyone serious about leveraging all the analytical information that is just sitting in Revit unused otherwise.


  • Makes Revit Electrical Usable
    Bryan Zapf | June 05, 2020

    As many of us know, the Building Suite from Autodesk takes a lot of financial resources throughout the year to support and maintain profitability.  Fortunately, Design Master gives us significant leverage and the ability to harness the power of Revit while completing our design in a more timely manner.  Our client base wants everything completed quicker and quicker.  Design Master helps us do that.  Many of our projects return with changes from either the Client or Architect.  Design Master is wonderful for not only producing a better power design in Revit but dealing with frequent changes in a more timely manner.  We cannot thank Dave and his team for prompt responses, timely support, professionalism and wonderful tutorials and upgrades.  We look forward to the new releases which will enhance the software and its capablities even more.  We cannot say enough about Design Master and highly recommend it to Revit MEP Engineers/Designers. Thank you.  

  • Design Master Electrical RT - An Essential Tool for Electrical Design
    Janice DuBois | April 16, 2020

    I was introduced to Design Master for AutoCAD in 2008. Using this software in AutoCAD became so second-nature, that our engineering department resisted a transition to using Revit MEP. With the advent of Design Master Electrical RT, I feel more comfortable and confident that my calculations are correct. Admittedly, I am still exploring the features it has to offer, but those I currently appreciate the most are the panel and circuit editing features, and the fact that I can trust the breaker sizes that populate panel schedules. When I have questions regarding the software, Design Master’s support team is incredibly responsive and helpful. I can’t imagine producing our designs without Design Master RT.

  • Excellent and Powerful!
    Shawn Sullivan | April 16, 2020

    Its to the point where I would not work at a firm that did not utilize DisignMaster Revit. Either that or I would puchase it myself. It is that helpful and time saving!

  • Great Electrical Engineering tool for Revit
    Jesus Alvarez | January 22, 2020

    Design Master saves us time by including some of the most common calculations we do right into Revit. It gathers information within Revit to help us with voltage drop calculations and preliminary short circuit studies for the whole project. The support team is knowledgeable and responsive as well.

  • An excellent daily-use tool for electrical Revit projects
    Norman Fisher | January 07, 2020

    Design Master Electrical RT is an essential and daily tool for me to produce electrical projects with Revit.  It is very useful for component instance editing, schedule creation and circuit editing.  I find it very useful and time-saving for automatically producing and updating One-Line diagrams.  It also provides me with many options that allow me to customize project parameters and outputs based on my clients' requirements.  Design Master's software support is also amongst the best I have encountered.  I highly recommend this product.

  • Time Saver and Coordination Tool in AutoCAD
    Azim Rawji | June 12, 2019

    This add-in is an absolute necessity for AutoCAD and Revit electrical design. We have been using DM electrical since 2006, the software enable you to circuit devices, automatically populates panel schedules, sizes circuit breakers and one-line diagrams. Calculates photometrics, voltage drop, AIC and arc flash. It is completely customizable. I highly recommend it for speed and accuracy for electrical design.

  • Electrical Engineering enabled in Revit
    Gary Edgington | June 12, 2019

    Having been an avid user of Design Master for CAD for 18 years, I am delighted to see it coming into the REVIT world.  It provides so much automation to the tasks n REVIT calculations , one lines and so many other tasks that have been overlooked in REVIT.  If there is one tool that made my transisition to REVIT possible, it would be DesignMaster RT.  Without that, tool we would still be in the dark ages of REVIT based electrical design.  The company has a proven track record of listening to the needs of their users and providing regular updates and constant improvments with new features.  Customer support is outstanding in the rare case you may have an issue, both timely and effective.  This is one of the software add-ins that you look forward to getting the next update with more tools and functionality adding to an already impressive list for electrical design professionals.  Well worth the modest investment and definately adds that professional touch to your design.

  • Electrical Design in Revit is Even Better
    Martin Mixon | February 15, 2018

    • Electrical calculations within Revit, no Excel sheets needed. • Automate your calculations and panel schedules. • Superb customer service. • User friendly interface and set-up. I highly recommend using Design Master with Revit to enhance and speed up your design. With a little customization to your schedules, it becomes a great tool to put you ahead of the competition.

  • Enable real electrical engineering in Revit
    Travis Premo | January 26, 2018

    Simply put, we could not do our electrical work in Revit without this add-in. After years of workarounds and muddling through the built-in electrical functionality of Revit, we found Design Master Electrical RT and haven't looked back. It's got it all: accurate wire sizing, accurate voltage drop, automatic sizing of everything, a ton of customization, the ability to customize your electrical families themselves, a ton of shared parameters, and AUTOMATIC SINGLE LINE DIAGRAMS. This add-in has replaced nearly all of the parameters and automatic calculations of Revit in our office because it's more accurate, more robust, and more flexible. To top it all off, the software is affordable and the customer service is top notch. Design Master also is constantly adding features and they have a feature request voting system so you can see what's in the works. You must try it if you are trying to do any real electrical work in Revit.

  • Electrical Engineers can DO IT ALL WITHIN REVIT NOW
    David Scott | January 19, 2018

    My company has been using RT since it was first released to market a few years ago and it has matured into an essential application for electrical design. As far as our group of 12 is concerned, there is no other alternative that even begins to compare with the feature set and convenience that this application adds to Revit's functionality. DM wisely created parameters that allow the user to pull RT data from the distribution system right into any Revit schedule or panel schedule which has allowed my team to use this already extremely powerful software package in even more ways than the description above. All of the project data generated by RT is stored in the Revit model so it is compatible with C4R (Revit in the Cloud) as well as Revit Server. Everything we need to be a more efficient, more productive design team are there...even the One Line Diagram - yes, it is finally complete, implemented and works incredibly well. This application is a no-brainer for electrical engineers. I am so glad that we invested in it when we did. Engineering calcs in Revit is a futile experience for EE's without it.

  • Finally a time saver for Revit
    Terry Jiracek | October 08, 2015

    If you are versed with Design Master for the Autocad side of Autodesk’s software the Revit version brings some much needed and very valuable tools from that software to the Revit table. The auto breaker sizing is a must for time saving as well as preventing in the field change order costs for the Revit default “20A” for all breakers that can sometimes slip though the final project back check. The ability to manually edit the breakers in the panels, base feeders and circuit sizes on calculated load is very useful. Also the ability to produce AIC calculations/ tables is a great checker for verifying panel values as well as real time voltage drop calculations that provide and quick back check real connected loads and distances. When the one- line portion of the program is available it will fill a very wide and much needed hole in Revit for electrical design.

  • A "Must Have" for Electrical design
    JAMES TATE | September 23, 2015 Verified Download (What's this?)

    This app takes up where Revit leaves off. Once installed, you can work within the Revit application (no exporting values to a spreadsheet or other software) to automatically size breakers, calculate wire size, feeder voltage drop, Branch AIC and arc flash information. There are options for "manual entry or adjustment" for just about everything imaginable. DM Electrical is working on a "riser diagram" feature. This application seems to be in active development and the team working on this app is responsive and already has an established history of electrical design software for AutoCAD. We are very pleased. There is certainly room for improvement, but this takes Revit years ahead of where it is now.
