ElectroBIM Release Notes

The following is a list of new and updated features in ElectroBIM 2.8.

AI Design Review

New commands in the AI panel of the ElectroBIM Design ribbon allow you to send electrical data for your Revit model directly to an AI for analysis, or export that data to use with an AI model of your choice.

For this release, the analysis is scoped to panels, transformers, and feeders. The scope may increase based upon feature uptake and user feedback.

Wire Label Customization

Neutral wire label, Ground wire label, and Isolated ground wire label have been added to the Project Options command. These fields allow you to customize the labels appended to these wires in wire callouts.

More Fields Driven by Revit Parameters

The following is a list of new and updated features in ElectroBIM 2.7.

Improved Multi-User Support

This release improves support for workshare-enabled projects that have multiple people working on them.

When elements are being modified by other users, calculations will complete. The borrowed elements will not be updated; everything else that can be updated will be updated.

A new dialog box will display information about elements borrowed by other users. This information will help you coordinate synchronizing your project with your other team members.

The new DMET_LastModified shared parameter will display when the element was last updated by ElectroBIM.

Watch the ElectroBIM 2.6 New Features Webinar on YouTube.

Generate Riser

The Generate Riser command allows you to insert part or all of your single-line diagram into a Revit drafting view in a riser configuration. Simply run the command, select a starting point, and the software will do the rest.

New settings in the the Family Edit and Project Options commands allow you to customize which graphics are used for each device and feeder when it is generated, and can be used to specify different graphics depending on whether you use Generate Riser or Generate One-Line.

New & Updated Single-Line Diagram Drafting Commands

Several commands have been added to or modified on the EBIM Single-Line ribbon, allowing you to make changes to device locations and feeders more easily:

• Equipment Move: Used to move distribution equipment and have connected feeder segments automatically update to the new location.
• Feeder Auto Draw: Formerly Feeder Reset. This command has been renamed to better describe its functionality.
• Feeder Manual Draw: Formerly Feeder Draw. This command has been renamed to better describe its functionality.
• Feeder Swap: Transposes two parallel feeder segments.
• Segment Move: Used to move feeder segments and have connected feeder segments automatically update to the new location.
• Segment Insert: Adds segments to a feeder.
• Segment Break: Adds bends to a feeder segment.
• Segment Offset: Sets the distance between and ordering of parallel feeder segments.
• Segment Align: Aligns parallel feeder segments.
• Segment Delete: Removes a feeder segment and, when possible, joins previously connected feeder segments.

Updated Single-Line Diagram Graphics & Tags

Several graphic families, annotation families, and projects have been updated, either to make them compatible with the Generate Riser command or to fix issues.

When you install the update, a set of our default customization will also be installed in the same location. The default location is C:Program FilesDesign Master SoftwareElectrical RTCustomization. As long as your customization folder is not set to this location, the graphic families in your customization folder will not be overwritten.

If you want to update your existing families, you will need to add the updated families to your customization folder manually. You can find your customization folder location by running the User Options command. Copy the files from your install location and paste them into your customization folder.

New Behavior for Lugs Connections

For the OCP Trip field in the Panel Edit command, the default setting has been modified.

Previously, the Same as main disconnect or bus size / lugs if transformer setting would recognize upstream connections to a transformer and remove the OCP from the model and single-line diagram accordingly. That behavior has now been expanded to include upstream connections to top lugs or bottom lugs as well. The label for the setting has also been updated to reflect this functionality, to Same as main disconnect or bus size / none if lugs.

Metric Unit Inputs for Arc-Flash

Length inputs in the Arc-Flash Calculations section of the Panel Edit commandare now based upon the settings in the Revit Project Units command.

If the Revit length unit is Imperial, the equipment dimensions and working distance will continue to use feet and inches. If the Revit length unit is metric, the equipment dimensions and working distance will use millimeters.

The boundary distance will be displayed using the unit set in the Revit Project Units command for distance.

Ending Support for Single-Line Diagrams in AutoCAD

We began phasing out support for single-line diagrams in AutoCAD with the release of version 2.0. Now that users are able to generate both one-line and riser diagrams in Revit, these feature sets have reached parity and exporting the single-line to AutoCAD is no longer necessary.

The Export to AutoCAD command will not be available in Revit 2026 and newer. The command will continue to function in older versions of Revit.

New Feature Webinar

• Added support for Revit 2026.
• Clarified labels on voltage drop options to make their functionality more clear.
• Fixed performance issue in Circuit Edit command.
• Fixed error in Single-Line->Edit command that caused some changes to not be saved.

The following is a list of new and updated features in ElectroBIM 2.5.

Watch the ElectroBIM 2.5 New Features Webinar on YouTube.

Metric Unit Inputs for Lengths and Areas

Length and area inputs are now based upon the settings in the Revit Project Units command.

Feeder and circuit lengths now use the units set in the Revit Project Units command for length.

If the Revit area unit is Imperial, wire and conduit areas will continue to use square inches and circular mils. If the Revit area unit is metric, the areas will use square millimeters.

New Circuit Edit Dialog Box

The Circuit Edit dialog box has been updated.

The most noticable improvement is support for editing multiple circuits at once, including circuits on different panels.

New Family Edit Dialog Box

The Family Edit dialog box has been reorganized to be more usable.

All of the family types are displayed in a vertical list, making families with several types easier to manage.

Default settings for the family have been removed; each type is configured explicitly.

Multiple types can be edited at once. Settings can also be copied from one type to other types.

A new Set in Instance value is available for most settings. When selected, the setting is modified in the instance in the project instead of being fixed by the family.

Single-Line Diagram Graphics Customization Dialog Boxes

The Single-Line Diagram Device Graphics and Single-Line Diagram Feeder Graphics customization commands now have dialog boxes.

This change makes it easier to view and modify how the single-line diagram graphics are organized.

Ending New Features for Revit 2020

ElectroBIM on Revit 2020 is being frozen at version 2.4. The features described above will be available in Revit 2021 and later.

New Feature Webinar

• Fixed a number of crashes when drawing certain time-current curves.
• Fixed a bug in the Circuit Edit command to properly display circuit descriptions for downstream panels.
• Fixed a bug related to choosing the correct wire sizing group.
• Fixed a bug in Revit 2025 that prevented arc-flash stickers from printing properly.

• Fixed error in the Family Edit command that prevented shared parameters from being set for more than one type at a time.
• Fixed error in the Family Edit command that caused MCA, FLA, and MOCP to not be saved correctly.
• Fixed error in the Circuit Edit command displaying the active circuit correctly in some cases.

The following is a list of new and updated features in ElectroBIM 2.4.

Upsize Wires Automatically for Voltage Drop

Conductors can be automatically increased in size to account for voltage drop.

Settings for controlling the wire sizing can be found in the Project Options command. You can enable or disable upsizing in your project for feeders and branch circuits, as well as set the maximum voltage drop for each.

A new Voltage Drop Review command has been added. This command will create a Revit schedule that displays which conductors have been upsized, the new wire size, and the original wire size for comparison.

New Instance Edit Dialog Box

The Instance Edit dialog box has been updated.

The most noticable improvement is support for editing multiple instances at once; simply select the devices you want to edit, then run the command.

Import Wire Lengths from EVOLVE Electrical

Wire lengths from EVOLVE Electrical can be imported back into ElectroBIM using the new EVOLVE->Import command. These wire lengths will be used for voltage drop and fault calculations.

Breaker Search

A Search button has been added to the OCP Device Settings dialog box displayed when selecting a breaker curve. This feature will make it easier to find your desired breakers in our database.

Service Ground Letter for Feeder IDs

A new option has been added to the Project Options command to control the letter used to note a service ground on feeder IDs.

Previously, we used J for "supply side service jumper" from NEC 250.102(C). J is still available as an option if you want to continue using it, and will be the default setting for current projects.

For new projects, the default will be T for "transformer", which is the most common situation where you would use a service ground instead of an equipment ground.

You can also select S for "service".

Support for Revit 2025

Revit 2025 is supported.

There was a large internal change in Revit from .Net Framework 4.8 to .Net 8.0. This change doesn't have any obvious changes to users at the moment, and is good for the future development of Revit. However, it did require corresponding large internal changes to our software, which is why compatibility has been added to the beta release rather than released as a patch.

New Feature Webinar

• Fixed error with breaker curve selection being lost when viewing a breaker curve again.
• Fixed error message when MOCP is less than the smallest standard breaker.

The following is a list of new and updated features in ElectroBIM 2.3.

Drive ElectroBIM Values with Revit Parameters

Values in the Panel Edit, Instance Edit, and Family Edit commands can all be set to match Revit parameters. You can now use information from outside our software to drive our values.

Breaker Setting Shared Parameters

New shared parameters exist on distribution equipment and electrical systems that show the breaker or fuse curve settings.

These shared parameters can be used to schedule the breaker settings in your project.

Total Voltage Drop Parameter on Circuits

A new shared parameter on electrical systems shows the total voltage drop on the circuit. This value is the branch circuit voltage drop plus the feeder voltage drop for the electrical equipment that the circuit is connected to.

New Feature Webinar

• Documenting breaker settings using new shared parameters (00:35)
• Displaying total voltage drop for each circuit (02:24)
• Drive ElectroBIM values using Revit parameters (03:47)
• "What are some examples for using shared parameters to size the OCP for branch circuits?" (06:51)

• Fixed worksharing errors in the Panel Edit and Override Review commands.
• Updated Panel Edit command to list the family and type of the selected equipment.
• Fixed error when using shared parameters with units set to apparent power, electrical potential, power, or wattage.

The following is a list of new and updated features in Design Master Electrical RT 2.2.

Generate One-Line

The Generate One-Line command allows you to insert part or all of your single-line diagram into a Revit drafting view in a vertical one-line configuration. Simply run the command, select a starting point, and the software will do the rest.

New settings in the the Panel Edit, Instance Edit, Family Edit, and Project Options commands allow you to customize which graphics are used for each device and feeder when it is generated.

New single-line feeder connection points have been added to the Insert Connection Point command. You can now specify different connection points for top lugs and bottom lugs connections to your graphic families.

Export to EVOLVE

New fields have been added to the Panel Edit and Conduit Sizes commands that can be used to coordinate your Design Master Electrical RT conduit runs with EVOLVE Electrical. Assign Conduit Run Ids to your feeders, then use the new Export->EVOLVE command to generate an Excel file that can be imported into your EVOLVE project.

New Panel Edit Dialog Box

Several updates have been made to the Panel Edit dialog box. The UI has been given a new, cleaner look.

You can now select multiple equipment in the model, single-line, or dialog box, then make changes to all of the selected equipment at once.

In addition to the Tree list, you can now use the alphabetically sorted List to find your equipment.

Support for Custom Feeder IDs

For custom feeders, you can now define a custom feeder ID that will appear on the single-line diagram and feeder schedule.

Improvements to Calculate Commands

The Calculate Whole Project command now prompts for confirmation before running. This confirmation prompt has also been added to the Calculate Whole Project and Calculate Part of Project buttons in the Panel Edit command.

Options have been added to the Calculate Part of Project command that allow you to choose whether distribution equipment and/or branch circuit values are recalculated, and whether one-line diagram labels and graphics are updated.

Project Options Command Redesign

New categories have been added to the Project Options dialog box to accommodate settings for new features and make it easier to locate the settings you want to change. The Customization->Export and Customization->Import command toggles include these new categories.

New Feature Webinar

• The Generate One-Line command (00:33)
• Exporting conduit information to EVOLVE Electrical using the Export->EVOLVE command (02:52)
• Improvements to the Panel Edit command (06:32)
• Support for custom feeder IDs (07:38)

• Project Options command redesign (10:15)

• Updated product name to ElectroBIM.The names of the Quick Access pulldowns changed. If you use these, you will need to add them again in Revit.
• Updated "One-Line" to "Single-Line" in the UI. This change is strictly related to labels in our commands. The functionality is the same.
• Added support for additional breaker curves.
• Fixed crashes reported by users.
• Fixed error creating feeder IDs when hot and neutral wires are combined.

• Fixed numerous crashes reported by users.

• Improved performance of the Panel Edit command when the dialog box first opens.

• Fixed the Generate One-Line command to properly handle equipment already inserted on the drafting view.
• Fixed display error in Panel Edit that caused it to not show the correct family default for the Main Disconnect Type.
• Fixed error in the Conduit Sizes command when deleting conduit groups.

Design Master Electrical RT 2.1 includes three new features, detailed below.

We also added the following shared parameters for displaying Revit values on the one-line diagram:

• DMER_Type_Mark
• DMER_Type_Comments

Override Review Command

(Click the images below to expand)

The Override Review command lists all of the settings you have changed from the default value in the Panel Edit, Circuit Edit, and Instance Edit commands. The settings changed and their respective values are displayed. The Comment column allows you to enter a freeform text note documenting why each setting was changed. The full list can be exported to Excel for processing outside of our software.

Customization Export and Import Toggles

The Customization->Export and Customization->Import commands now have toggles to control which customization settings will be transferred. These toggles allow you to update some of your settings instead of all of them.

Ground Type Column Added to Feeder ID Schedules

The Project Feeder ID Schedule and Master Feeder ID Schedule commands now include a Ground Type column. When automatically generating feeder IDs, the software differentiates between feeders with a service ground (NEC 250.102) or equipment ground (NEC 250.122), even if the ground size is the same. This column makes it easier to understand why certain feeder IDs are being generated.

New Feature Webinar

• The Override Review command (00:17)
• Toggles in the Customization->Export and Customization->Import commands (04:19)
• Ground Type column added to feeder ID schedules (06:27)

• Added support for Revit 2024.
• Add support for speciality equipment.
• Fixed user reported crashes.

The following is a list of new and updated features in ElectroBIM 2.0.

One-Line Riser Diagrams in Revit

One-line riser diagrams can now be created in a Revit drafting view instead of in AutoCAD. The commands are available in a new DM One-Line tab.

Detailed tutorials on using the new one-line diagrams will be available soon.

Tip: On projects where panels and transformers are already created, use the Insert Link command to insert them on the one-line diagram. On new projects, use the Insert Create command to create panels and transformers and insert them on the one-line diagram simultaneously.

Breaker Curves: Selective Coordination & Arc-Flash Trip Time

Breakers can be assigned time-current curves. The curves can be used for selective coordination and arc-flash trip times.

Selective Coordination: Multiple breaker curves can be displayed on a time-current graph to allow you to coordinate your breakers.

Arc-Flash Trip Times: The arcing time in the arc-flash calculation can be calculated automatically using the breaker curve.

Calculation Upgrades

Fault on Branch Circuits: Fault values are calculated and displayed on branch circuits and branch circuit devices. These values can be used for displaying the fault at motors and other equipment in your project.

Custom Transformer OCP Sizes: You can customize the default OCP sizes for transformers using the new Transformer OCP Sizes command.

Custom Wire Callouts: A new Custom option is available for conductor sizes. You can specify the text used as the wire callout and the impedance values. Custom callouts can be used for one-off feeders, such as in existing projects. They can also be used for connections that are not wires, such as bus bars.

Specific Wire Sizing Option: If you have multiple wire sizing options defined in the Wire Ampacities command, you can assign a specific option to a feeder or branch circuit. One option is always the default used for sizing wires in a project. You can now choose to use a different option for one feeder in the project. The wire will still size automatically but will use the selected option. For example, if you have a single feeder you want to be aluminum, you can set it to an aluminum sizing option. It will automatically size to the correct aluminum wire size.

Separate Breaker and Wire Ampacity: Wire ampacity is now set separately from breaker ampacity. Generally, breaker ampacity is used to choose the wire size. If the wire is derated, wire ampacity is used. If the wire ampacity falls below the breaker ampacity, a larger wire size is chosen.

Double Neutral Wire Sizing: When the neutral size is set to Double phase, the neutral wire is assumed to be a current-carrying conductor. For circuits with three conductors, the conductor is adjusted based upon NEC 310.15(C)(1).

Ambient Temperature: The ambient temperature for the project and for specific runs of wire can be specified. The ambient temperature is used to adjust the conductor size based upon NEC 310.15(B)(1). The initial ambient temperature for projects is set at 30°C.

Calculate Part of Project & Highlight Buttons

A Calculate Part of Project button has been added to the Panel Edit command, allowing you to run the command and see the changes without closing the dialog box.

Highlight Panel and Highlight Circuit buttons have been added to the Panel Edit and Circuit Edit commands. Use these buttons to locate your devices in the Revit model.

Homerun Wire Callout Parameter

A new DMET_Circuit_WireCalloutHR parameter was added to circuits. If the wire is #10 or larger, this parameter will display the wire callout. If the wire is #12, it will be blank. Use this parameter to label wire sizes on large homeruns and leave wire sizes off on smaller ones.

Pulldown Menus

The two DM ribbon tabs each have a pulldown button that can be added to your Quick Access Toolbar, allowing access to the Design Master commands without needing to switch between ribbon tabs. The pulldown includes most of the commands on the ribbon tab.

Revit Version Support

This version supports Revit 2018, 2019, 2020, 2021, and 2022. We will continue to support the current version of Revit plus the last three versions. As new versions of Revit are released, we will stop adding features to older versions of Revit.

Previous versions of our add-in will continue to be available for older versions of Revit.

Phasing Out Support for One-Line Diagrams in AutoCAD

Support for one-line diagrams in AutoCAD will slowly be phased out. This phase-out will not be immediate. Current projects that use one-line diagrams in AutoCAD can be finished in AutoCAD. The Export to AutoCAD command is still available on the DM One-Line tab.

We do not recommend starting one-line diagrams in AutoCAD for new projects.

Some new features will not work correctly with AutoCAD one-line diagrams. In this release, Additional Wire Sizing Options and Custom Wire Callouts will not transfer properly to AutoCAD. Wires that use those features may be labeled incorrectly in AutoCAD.

• Changed branch circuit fault calculations to work on circuits with up to 3 devices. Previously, it was limited to circuits with only 1 device.
• Fixed numerous crashes reported by users.
• Updated the Insert Link, Copy Link, and Change Link commands to load faster.
