ElectroBIM is a Design Master add-in for Revit that draws single-line diagrams and runs voltage drop, fault, feeder, arc-flash, and coordination calculations in the electrical model.
Electrical teams often keep a riser in Revit and the fault study in another program. ElectroBIM keeps the one-line, the panel data, and the calculations in the same model, so a load or breaker change can update the connected graphics without an export step. Shared parameters on the diagram are what the vendor uses to keep sheet graphics aligned with those revisions.
Voltage drop uses the wire size you picked and the feeder or branch length taken from equipment locations in the model. Fault current is calculated at the equipment, with a schedule for the available fault and the AIC rating. Breakers size from the branch load, wires size from that breaker, and feeders can size from the required overcurrent protection.
Arc-flash incident energy is calculated for every panel, and a schedule of that energy and the required PPE is published into Revit. A breaker database supplies time-current curves so several devices can be graphed together for selective coordination. Offices that also use EVOLVE Electrical can send conduit sizes across and pull wire lengths back.
The current installer supports Revit 2021 through Revit 2027 on a PC that can run those versions. Design Master still lists Windows 7 SP1 or later and a 1360 by 768 screen as the floor. Revit 2014 through 2020 run only on an older build with no updates or support. Revit LT and any non-Revit BIM tool are not supported.

Pros and cons
Pros
- Calculations and the one-line live in the Revit model
- Published yearly and monthly seat prices, with a full-featured trial the site labels as having no expiration
- Revit 2021 through 2027 are on the current support list
Cons
- Floating licenses require at least 5 seats
- Revit LT is not supported, and Revit 2014 through 2020 are on an older build without updates
Key features
Single-line risers: Diagrams stay in Revit and update from shared parameters when the design changes.
Voltage drop: Uses the selected wire size and lengths taken from equipment locations in the model.
Fault current: Calculates available fault at equipment and documents it with the AIC rating.
Feeder, breaker, and wire sizing: Breakers follow the branch load, wires follow the breaker, and feeders can follow the required overcurrent device.
Arc-flash and coordination: Incident energy and PPE land in a Revit schedule. Time-current curves can be graphed together.
EVOLVE Electrical: Conduit sizes can be sent to EVOLVE, and wire lengths can be pulled back into ElectroBIM.

Frequently asked questions
How much does ElectroBIM cost?
On the Design Master product page, a single-user seat is $250 per month or $2,500 per year. A single-site floating seat is $650 per month or $6,500 per year, and a multi-site floating seat is $800 per month or $8,000 per year. Floating licenses have a 5-seat minimum, so the 5-seat yearly buttons show $32,500 and $40,000. Yearly billing is labeled as two months free compared with paying every month.
Does ElectroBIM have a free trial, and how long is it?
Yes. The download button on the product page says Free Trial, Full-Featured, No Expiration. The free-trial page says you install ElectroBIM and evaluate it on your own projects, and it does not list a 30-day cutoff. Treat that label as the vendor's current wording and confirm it if a time limit matters to the purchase.
Which Revit versions and Windows releases does ElectroBIM support?
The current installer lists Revit 2021 through Revit 2027. Revit 2014 through 2020 work only on an older release that ships with the installer, and that build gets no updates or tech support. Revit LT is not supported, and neither is any BIM program other than Revit. Design Master asks for Windows 7 SP1 or later and a screen of at least 1360 by 768.
Can ElectroBIM calculate arc-flash and selective coordination?
Incident energy is calculated for every panel, and a schedule of that energy and the required PPE is published into Revit. Selective coordination uses a time-current curve database so project breakers can be assigned and several curves graphed together. Voltage drop, fault current, feeder sizing, and branch breaker and wire sizing are in the same model.
Does ElectroBIM build the single-line diagram inside Revit?
Yes. The one-line riser is drawn in Revit and stays tied to shared parameters, so a revision can update the sheet without a separate diagram file. There is no import, link, or sync step to a second electrical program for that graphic. Feeder lengths used in the calculations come from equipment locations in the model.
How does ElectroBIM compare with a standalone fault-study program?
Design Master positions ElectroBIM as the calculation set that stays inside Revit, and a McMahon Associates quote on the page says that, with good utility data, the results match high-powered programs they already knew. The difference they emphasize is that the one-line and the study share the model. It does not claim to replace a full power-system suite outside Revit, and it does not run in Revit LT.
