In Autodesk Revit Electrical Design, when an electrical designer attempts to control a receptacle (an Electrical Fixture family) with a switch (a Lighting Device family) as part of a switch system, Revit will only allow this connection if the receptacle’s family has been configured as Switchable within the Family Editor.

According to the Autodesk Revit MEP User’s Guide (Chapter 17 – “Electrical Systems”):

“Revit allows you to add elements such as lighting fixtures or receptacles to a switch system only if the family includes a switchable connector. The ‘Switchable’ parameter must be enabled in the Family Editor to allow this connection.”

This means that for the receptacle shown in the exhibit to appear as an available component for switching, the Electrical Connector within its family must have the Switchable property checked. This parameter is found under:

Family Editor → Select Connector → Properties Palette → Electrical - Data → Switchable.

If this option is not enabled, Revit treats the receptacle as a standard unswitched outlet and will not display it in the switch system creation dialog. Once the option is checked, the designer can reload the family into the project and associate it with a switch system normally.

Additionally, the Smithsonian Facilities Revit Template User’s Guide explains this concept as follows:

“To associate receptacles with lighting switches, ensure that the receptacle family has a switchable connector. Without this setting, the device will not appear as an assignable component to a switch system.”

This distinction is important in residential electrical modeling, where switched receptacles are common for plug-in lamps. Lighting circuits can include both Lighting Fixtures and Switchable Receptacles when the family configuration supports it.

Incorrect Options Explanation:

A. A switch system not being created is irrelevant — the issue occurs before system creation.

C. Being on the same circuit doesn’t affect switchability; it affects electrical load connection.

D. Incorrect — Revit supports switchable receptacles if properly configured.

Therefore, the correct answer is B. The receptacle’s “Switchable” option is not selected within the family editor.

To allow conduit to be modeled from any point on a specific side of the electrical equipment, the most accurate method is to use the "Surface Connector". This method enables the designer to place a surface-based conduit connector on a specific face of the equipment family. Here's how the process is explained:

"To place a conduit connector on the surface of a family component so that the conduit can start from anywhere on that surface, use the Surface Connector option. This connector attaches to the selected face of the equipment, allowing conduit to be drawn directly from any point on the selected face in the project environment."

"Click Conduit Connector, then choose Surface Connector, and select the face where the conduit should connect. This gives flexibility in modeling, especially for equipment requiring multiple connection points across a single face or allowing freedom of routing."

This process is especially beneficial in custom electrical equipment families where conduits must originate from arbitrary points along a flat side—ensuring both parametric flexibility and coordination ease within the project environment.

In contrast:

Option A refers to editing connector dimensions, which does not affect the connector's ability to accept connections from any surface point.

Option B uses Individual Connector which limits the connection to a specific point, not the whole face.

Option D refers to changing connector type in the Properties palette, which doesn't impact connector location or coverage on a face.

The exhibit shown in the image is taken directly from the Revit MEP Electrical Systems workspace, specifically from the Parallel Conduits command interface. This dialog box appears when the designer activates the Place Parallel Conduits tool in the Systems tab → Electrical panel → Conduit dropdown → Parallel Conduits.

In this interface, the designer can specify:

Horizontal Number / Offset – defines how many conduits will be created horizontally and their spacing.

Vertical Number / Offset – defines how many conduits will be created vertically and their spacing.

Bend Radius Options:

Same Bend Radius – all conduits use identical bend radii.

Concentric Bend Radius – conduits bend concentrically around a common center point.

According to Autodesk’s Revit MEP 2011 User’s Guide (Chapter 18, Electrical Systems – Conduit Layout):

“The Parallel Conduits tool allows you to create multiple conduits side-by-side at the same time.

You can specify the number of conduits horizontally and vertically, as well as the offset between them.

You can also define whether bends have the same bend radius or concentric bend radii.”

— Revit MEP User’s Guide, Electrical Systems, Section: Conduit Layout

This tool is used when electrical designers need to route groups of conduits that run in parallel—such as power and data conduits running between panels or equipment racks.

The Concentric Bend Radius option (as shown in the exhibit) ensures all conduit bends share a common center, which is critical for maintaining uniformity in conduit sweeps and avoiding clashes during coordination.

Therefore:

A. Add Cable Tray – incorrect; the cable tray tool is separate and does not use bend radius options.

C. Array Conduit – incorrect; arraying is a different geometric function not specific to conduit routing.

D. Place Multiple Pipe – incorrect; applies to mechanical piping systems, not electrical conduits.

The display of Concentric Bend Radius, Horizontal Number, Vertical Number, and Offset confirms that the designer is using the Parallel Conduit placement tool.

In the exhibit, the designer expects the total connected load to equal the sum of the 4 motor loads:

4 motors × 1000 VA each = 4000 VA expected

However, Revit is showing a Total Connected Load of 3606 VA instead.

This difference occurs because Revit applies Motor Demand Factors automatically when a load classification is set to “Motor.” Demand factors modify the total connected load based on electrical engineering rules.

Revit documentation confirms:

“Assign demand factors to load classifications.”

“Demand loads can be shown on panel schedules.”

In the exhibit, the Load Classification shows Motor with a Demand Factor of 117.87%, which modifies the connected load values in the switchboard totals.

Revit is therefore calculating the effective connected load based on the applied demand factor, not a simple arithmetic sum. That is why the panel’s connected load number ≠ 4000 VA.

In Revit Electrical Design, the Selection Box tool is used to quickly isolate and display selected components in a cropped 3D view. When an electrical designer selects conduits or devices in a model and chooses Selection Box from the Modify tab, Revit automatically generates a 3D view bounded tightly around the selected elements, helping coordinate routing in confined or congested spaces.

According to the Revit MEP User’s Guide under “Creating 3D Views”:

“Use the Selection Box tool to create a 3D view that isolates selected elements. Revit automatically crops the view extents to the selected geometry.”

This feature is critical in multidisciplinary coordination because it allows the electrical designer to review specific conduits, cable trays, or lighting paths in context without manually adjusting view boundaries.

In contrast:

Default 3D View (Option B) shows the entire model.

Scope Box (Option C) controls view extents in 2D views or view templates, not instant isolation.

Section Box (Option D) is manually adjusted within an existing 3D view but does not automatically generate a cropped view around selected elements.

Therefore, the Selection Box is the correct and most efficient tool for this task.

In Revit Electrical Design, for a loadable family (such as electrical equipment, lighting fixtures, or devices) to connect to a power circuit, it must include an electrical connector defined in the Family Editor.

According to the Autodesk Revit MEP User’s Guide (Chapter 17 – Electrical Systems):

“For an electrical family to participate in a circuit, the family must contain an electrical connector. The connector defines the relationship between the component and the electrical system. Without a connector, Revit cannot establish a power connection, and the Power tool will not be available.”

— Revit MEP User’s Guide, Electrical Systems – Creating Electrical Families

The connector type determines what kind of system (Power, Data, Communication, etc.) the family can join. When the electrical connector is not added, Revit cannot recognize the family as part of an electrical system, and thus the Power icon is grayed out or unavailable.

Incorrect Options:

A. Set the distribution system for the family – only available after a connector is added.

B. Set the family parameter to Shared – allows tagging or scheduling across projects but does not affect connectivity.

C. Change the Voltage parameter value – affects circuit data but not connection availability.

Therefore, the issue is resolved only by adding an electrical connector in the Family Editor.

In Autodesk Revit, a drafting view is a 2D view that contains detail information not directly associated with the model. When an electrical designer needs to reuse a drafting view from another project (for example, standard details or symbols), the correct method is to use the Insert Views from File command under the Insert tab.

The Autodesk Revit MEP User’s Guide – Chapter 48 “Detailing” (page 1072) describes the process as follows:

“Inserting a Drafting View from Another Project

Click Insert tab ➤ Import panel ➤ Insert from File drop-down ➤ Insert Views from File.

In the Open dialog, select a project file, and click Open.

The Insert Views dialog opens, displaying all the views that are saved in that project.

Select the desired drafting views and click OK.”(Revit MEP User’s Guide, p. 1072)

This command imports the drafting view into the current Revit model while preserving annotations, filled regions, detail components, and text. It ensures that any standard electrical symbols, notes, or schematics created previously can be directly reused without rebuilding the detail from scratch.

If any duplicate type names exist, Revit automatically uses the types and properties from the current project, displaying a warning if necessary.

“Revit MEP creates a new drafting view with all the 2D components and text. If you have duplicate type names, the type name and properties from the current project are used.”

(Revit MEP User’s Guide, p. 1072)

In Autodesk Revit Electrical Design, a lighting device (switch) must be associated with lighting fixtures through a switch system, not through electrical circuits. Switch systems are independent of lighting circuits and wiring, as they are intended to represent the control relationship between a light switch and the lighting fixtures it operates.

According to the Autodesk Revit MEP User’s Guide (Chapter 17 – Electrical Systems, pages 475–478), the official method is described under “Creating a Switch System.”

“You can assign lighting fixtures to specific switches in a project.

The switch system is independent of lighting circuits and wiring.”

(Revit MEP User’s Guide, p. 475)

“To create a switch system:

Select one or more lighting fixtures in a view, and clickModify | Lighting Fixtures tab ➤ Create Systems panel ➤ Switch.

Click Switch Systems tab ➤ System Tools panel ➤ Edit Switch System.

Click Add to System, and select one or more lighting fixtures.

Click Select Switch, and select a switch in the drawing area.

Click Finish Editing System.”**(Revit MEP User’s Guide, p. 476)

How It Works:

The switch system links a lighting device (switch) with lighting fixtures, enabling Revit to manage how light fixtures respond to specific switches.

Unlike electrical circuits, which define power flow and load connections to panels, the switch system defines control logic (which lights are turned on/off by which switch).

The designer begins by selecting the switch and then adding lights to its system, ensuring all lights associated with that switch are grouped correctly.

Supporting Extract from Revit Documentation:

“You can also create a lighting switch system by right-clicking the connector for a lighting fixture and clicking Create Switch System.”

(Revit MEP User’s Guide, p. 475)

“Add lighting fixtures to the switch system…

Click Select Switch and select a switch in the drawing area.”

(Revit MEP User’s Guide, p. 476)

“The switch system is independent of lighting circuits and wiring.”

(Revit MEP User’s Guide, p. 475)

Conclusion:

To associate a lighting device (switch) with light fixtures in a Revit electrical model, the designer must create a switch system. This is done by selecting the switch, then adding the desired lighting fixtures to that system using the Add to System and Select Switch tools under the Switch Systems tab.

In Autodesk Revit, phasing allows designers to track existing, demolished, and new elements across different project stages. Every model element includes two key phasing parameters:

Phase Created — defines when the element was built or introduced.

Phase Demolished — defines when the element is removed or demolished.

In the provided exhibits:

The project contains two phases: Existing and New Construction.

The receptacle’s Phase Created parameter is set to Existing, indicating it belongs to the pre-existing building condition.

The architectural wall hosting the receptacle is to be demolished during New Construction.

When a view’s Phase is set to New Construction and its Phase Filter is configured to show demolition, only elements whose Phase Demolished equals New Construction will appear as to be demolished. Therefore, the electrical designer must set the receptacle’s Phase Demolished value to New Construction so that it graphically displays as a demolished element in the demolition plan.

As explained in the Autodesk Revit MEP User’s Guide – Phasing and Coordination:

“Elements created in one phase and demolished in a subsequent phase must have their ‘Phase Demolished’ parameter set to that later phase to display properly in demolition views.”

Thus, to correctly coordinate with the demolition of its host wall, the receptacle must be flagged for demolition during New Construction.

The parameter “Lighting Calculation Luminaire Plane: Not Computed” in the Space Properties dialog appears when Revit cannot perform a lighting calculation because no valid lighting fixtures are present within that defined space.

According to the Autodesk Revit MEP User’s Guide (Chapter: Spaces and Lighting Analysis):

“Lighting calculations are performed based on the luminaire data available in the space. If no light fixtures are present, the parameter ‘Lighting Calculation Luminaire Plane’ displays as ‘Not Computed’. Revit requires at least one hosted or ceiling-mounted lighting fixture with a valid light source to calculate illumination.”

In this case, although the space has defined reflectance values (ceiling, wall, and floor) and a lighting calculation workplane height (2’-6”), Revit cannot compute the Luminaire Plane because the software has no lighting geometry to reference for the photometric analysis.

Explanation of incorrect options:

A. Missing IES file: This would cause inaccurate photometric output, but not “Not Computed.”

C. Lights not circuited: Circuiting affects load summaries, not lighting calculations.

D. Lights at different elevations: Revit still computes the average luminaire plane even with varied fixture heights.

Thus, the lighting calculation is not computed simply because no lighting fixtures are placed in the space.
