Creating a New Project

Click the Home button, and then the Add (+) button to create a new Project.


The Home Screen is a Project portal that provides quick access to recent Projects

Opening an Existing Project

Existing projects or recently opened projects are shown below the Open Project section.


Check the recently opened lists to pick up where you left off

Project Settings

Project Settings are a set of customizable parameters on which to base the design.


Project Settings are accessible by clicking on File, and then Settings


To help guide the design process, refer to the Roadmap. Clicking on each node will bring you to that process.



Defining Architectural Elements


The goal of the Architectural Workspaces, Floor Plans and Arch. Elements, is to provide a way for you to quickly mass the load of a building. These locations aid with point-to-point calculations such as voltage drop.

However, these Workspaces are completely optional. For a smaller project, you may not find it necessary to set up these Workspaces and instead, find it faster to manually input feeder lengths in the One-Line.

This information can be imported from an Architectural Revit model.

The Arch. Elements Workspace allows you to modify the architectural elements of the model. Here, it is possible to modify other characteristics of a Floor. For example, when massing the load of a building, you may want to assign a load requirement or load density to each Floor. This load is based off of the Floor’s Space Type.

These elements can be created in the Floor Plans Workspace, or the Architectural Elements Workspace.

Equipment Distances

Calculated Length

Distances between Equipment are determined by their respective Room locations. Calc. Length (Calculated) represents the distance between two Rooms via an orthogonal route.

The vertical distance between Rooms is the difference between their respective elevations.


Route between Rooms on the same Floor, and vertical distance between stacked Rooms

It is often necessary to offset through a Riser. The total distance or Net Length is determined by the centerpoints of the respective entities.

Manual Added Length

Manual Added Length is an additional factor which is added to a circuit’s Calc. Length property and is a customizable default setting. See here for more information.

Net Length

The Net Length is composed of the Calc. Length and the Manual Added Length.

Loading System

The Architectural Elements are the unifying components which Engineers base their design. However, various engineering disciplines refine and base their calculations off of different elements.

You have the ability to abstract the architectural elements of a model to create Load Packages. Ideally these entities would be abstracted away from a Revit model. However, during the early stages of development, a Revit model may not exist.

Creation of these architectural entities allow for the THRUX engine to fully utilize its Loading System which applies loading factors dictated by the designer and the Project’s applicable safety codes and standards.


Creating Architectural Packages to model loads

Modeling residential loads relies on creating entities that are based off of the NEC.


Creating Architectural Packages to model residential loads

Groups of architectural entities can be created within THRUX, or imported from a Revit model. Ultimately, Architectural Packages are loads that can be attached to Equipment.

Floor Plans

The Floor Plans Workspace is a 2-D representation of the Project and is used to model locations of Equipment.

Building the Electrical Model


There are three (3) main Workspaces to build the electrical system.

These include: Riser, One-Line, Schedules.

Reports of a model can be generated at any time using the Studies Workspace.

Hosted vs. Unhosted Systems

If a piece of Equipment is not fed from a source, then it is designated as Unhosted. During the stages of design, it is common to model hypothetical scenarios before all information is known. For example, as part of a larger project, an Architect may decide to create a space dedicated for a computer lab, but not yet decide on its exact location. While the location is not yet finalized, you can still model an Unhosted System with the intent of attaching the system to the main network in the future. Modeling Unhosted Systems allows flexibility when the source of a network is not yet known or if you want to create segregated distribution networks and tie them together at a later time.

Pricing Model

The Pricing Model is built around the Electrical model and can be viewed in a few Workspaces. The Price Tracker is used to live monitor the price of the model. For example, as you change the location of a major equipment room, the Price Tracker would display order of magnitude estimates for that change. For a more complete tabular report, use the Pricing Report Workspace.

Equipment Rates is a customizable catalog which composes the bid for materials.

Project Management

Engineers are often tasked to study different alternatives or schemes and present them to the Owner.

The Issuance Log allows you to create Branches, while the Change Tracking Workspace allows you to compare Branches against the base Branch.

Explorers and other Utility Tools

The right-side toolbar of THRUX is generally where the explorers or utility tools are located. Explorers can be pinned to always be visible while other explorers are being used.

Recovery Options

THRUX models are stored in the cloud and are periodically backed up. If THRUX crashes, reopen THRUX. A recovery window will prompt to restore to the latest restore point, or an earlier restore point.


Another option is to restore a model to a restore point via the Open Project window. Use the Restore button (restore icon) and then choose a restore point.


Automatic Updates

Whenever THRUX is opened, it automatically searches for updates.

Refer to the Version Number in the bottom right of the Status Bar.


To see an outline of updates between each Version, click on the information icon located in the top-right of the top menu bar.


Use the arrows to navigate between each Version.


Revit Interoperability

The Architectural information which comprise the Architectural Workspaces, Arch. Elements and the Floor Plans, can be imported from a Revit model.

In addition, a THRUX model can be exported to Revit. You can then fine-tune Equipment locations using Revit, and verify the integrity of the design using THRUX.


AutoCAD Interoperability

Schedules are exportable to AutoCAD or Excel.
