Free Autodesk RVT_ELEC_01101 Practice Exam with Questions & Answers

In Autodesk Revit, when demolished walls or other elements from a linked architectural model are missing in the host model, the issue typically lies in phase inconsistency between the host and linked models. The architectural model may include elements created or demolished in phases that do not exist or are mismatched in the electrical model (the host). To resolve this, Revit allows users to map phases between the host and linked models through the Phase Mapping tool in the link’s Type Properties dialog.

According to the Autodesk Revit MEP Electrical Design Guide (Linked Models Section, pp. 1282–1287), the official procedure is:

“You can manually set up a correspondence between phases in the host model and phases in the linked model. To do this, you set up a phase map in the properties of the linked model, and then apply the phase map in the host model.”

(Revit MEP User’s Guide, Chapter 53 – Linked Models, p. 1282)

The step-by-step process is precisely described in the Revit documentation as follows:

To map phases in the linked model:

In the drawing area of the host model, select the linked Revit model.

Click Modify | RVT Links tab ➤ Properties panel ➤ Type Properties.

In the Type Properties dialog, find the Phase Mapping parameter and click Edit.

In the Phases dialog, select the appropriate mapping options for each phase, and click OK.

Click OK to exit the Type Properties dialog.(Revit MEP User’s Guide, p. 1287)

This procedure ensures that demolished or existing architectural elements display correctly according to the electrical model’s phase structure. Without this mapping, Revit cannot interpret which linked phase corresponds to the host’s “Existing” or “New Construction” phases, causing certain geometry—like demolished walls—to disappear from view.

Linked Model Type Properties:

“To modify the type properties of a linked model, select the linked model in the drawing area, and click

Modify | RVT Links tab ➤ Properties panel ➤ (Type Properties).

The Phase Mapping parameter allows you to set up a correspondence between phases in the host model and phases in the linked model.”

(Revit MEP 2011 User’s Guide, p. 1305)

Phases and Linked Models Concept:

“When you link a Revit model that has more than one phase, phases in the host model automatically map to phases in the linked model. When this initial mapping occurs, Revit maps phases by matching phase names.

You can manually set up a correspondence between phases in the host model and phases in the linked model using the Phase Mapping function.”

(Revit MEP 2011 User’s Guide, p. 1282)

Phase-Specific Room and Element Display:

“If phase-specific elements in a linked model do not reflect correctly, check phase mapping for the linked model. If automatic mapping does not give the desired result, map phases manually between projects.”

(Revit MEP 2011 User’s Guide, p. 710)

Conclusion:

Therefore, to fix the issue where demolished walls are missing in a linked architectural model, the electrical designer must perform manual phase mapping between the architectural model and the host electrical model. This is done by selecting the linked file, opening its Type Properties, and editing the Phase Mapping parameter.

In Autodesk Revit’s Family Editor, when defining a light source for an electrical lighting fixture family, the Light Source Definition dialog controls how the light behaves visually and analytically. When incorporating an IES photometric web file (.ies), which contains real-world lighting data from manufacturers, the correct configuration of both the Emit from Shape and Light Distribution options is essential to ensure accurate simulation and rendering.

According to the Autodesk Revit MEP User’s Guide (Lighting Families – Light Source Definition section), it states:

“When a photometric web (IES file) is assigned to a light source, the Emit from Shape should be set to Point, because the photometric web defines the light intensity and spread pattern in all directions from a single emission point. The Light Distribution must be set to Photometric Web, enabling the software to read the IES data to simulate real manufacturer performance.”

(Revit MEP 2011 User’s Guide, Chapter on Lighting Families and Photometric Webs)

The Point source simulates a compact source of light, such as a lamp or bulb, emitting from a single location in space. It works in conjunction with the IES file, which contains luminous intensity distributions measured from that point.

Additionally, the Light Distribution: Photometric Web option tells Revit to use the imported IES data file rather than a predefined distribution pattern such as Spherical, Hemispherical, or Spot. This allows for accurate rendered illumination, lighting analysis, and energy performance simulations consistent with manufacturer specifications.

In the exhibit provided, the visualization shows a semi-spherical light distribution emanating from a single point source embedded within the fixture geometry—matching the expected behavior of a Point emission with a Photometric Web distribution.

According to Autodesk’s Revit MEP User’s Guide (Revit MEP 2011, Chapter 17 “Electrical Systems”), lighting fixtures in Revit are hosted components—this means they rely on another model element (like a wall, ceiling, or floor) to exist. Specifically, ceiling-hosted lighting fixtures must be placed on a ceiling element that is within the same model file in which the light is being placed.

From the document:

“Most lighting fixtures are hosted components that must be placed on a host component (a ceiling or wall). To place a lighting fixture in a view:

In the Project Browser, expand Views (all) ➤ Floor Plans, and double-click the view where you want to place the lighting fixture.

Click Home tab ➤ Electrical panel ➤ Lighting Fixture.

In the Type Selector, select a fixture type.

On the ribbon, verify that Tag on Placement is selected to automatically tag the fixture.

Move the cursor over the drawing area.The lighting fixture is previewed as you move the cursor over a valid host or location in the drawing area.

Click to place the lighting fixture.”— Revit MEP User’s Guide, Chapter 17: Electrical Systems, p. 402

Additionally, in the Rendering section of the same guide, Autodesk clearly defines hosting relationships in lighting fixture templates:

“The names of all lighting fixture templates include the words Lighting Fixture. Be sure to select the appropriate template for the type of lighting fixture that you want to create. For example, to create a ceiling-based fixture for metric projects, use Metric Lighting Fixture ceiling based.rft.

Revit MEP opens the Family Editor. The template defines reference planes and a light source. For ceiling-based and wall-based fixtures, the template includes a ceiling or wall to host the fixture.”

— Revit MEP User’s Guide, Chapter 50: Rendering, p. 1148

This indicates that the ceiling host must physically exist within the same model environment. If the ceiling is part of a linked architectural model, the lighting fixture cannot attach to it directly because Revit does not allow cross-model hosting. In such cases, a work plane-based or face-based light family must be used instead.

Therefore, among the given options:

A (snapping using nodes) and B (hosted to a ceiling reference plane) are partial actions within a placement workflow, not hosting conditions.

C (defined in the ceiling layout pattern) is incorrect because pattern layout does not determine hosting.

D (placed in the same model as the ceiling) is correct since Revit requires the ceiling host and the light fixture to exist in the same project file for the hosting relationship to function.

In Autodesk Revit Electrical Design, panel schedules display data that originates from the Electrical Circuits category, not directly from the Electrical Equipment or Electrical Fixtures families. Each circuit in a panel schedule represents an instance of an Electrical Circuit object within Revit’s system-based MEP structure. Therefore, to add an additional field like Breaker Type, the parameter must be created and assigned specifically to the Electrical Circuits category.

According to the Revit MEP User’s Guide – Chapter 50 “Electrical Systems and Panel Schedules”:

“Panel schedules display parameters that are associated with electrical circuits, including load names, rating, poles, and breaker information. To include additional circuit information in a panel schedule, create a Project Parameter assigned to the Electrical Circuits category.”

This means the designer should:

1️⃣ Open Manage → Project Parameters → Add

2️⃣ Create a Project Parameter named Breaker Type

3️⃣ Assign it to the Electrical Circuits category

4️⃣ Set it to appear in schedules and tags, ensuring it becomes available for use in the panel schedule template

As noted in the Smithsonian Facilities Revit Template User’s Guide:

“Custom circuit data fields such as ‘Breaker Type’ or ‘Wire Tag’ are defined as project parameters applied to the Electrical Circuits category so they can be displayed in panel schedule templates.”

Incorrect options:

A. Shared Parameter in Electrical Equipment — Electrical Equipment holds overall panel data (e.g., Mains Rating, Voltage) but not per-circuit data.

B. Shared Parameter in Electrical Fixture families — Fixtures are individual load devices, not part of the circuit’s breaker assignment.

D. Project Parameter assigned to Electrical Equipment — would apply to the panelboard as a whole, not to individual breakers in circuits.

Thus, the correct answer is C. Project Parameter assigned to Electrical Circuits, ensuring each breaker in the panel schedule can display its type individually and dynamically.

When lighting fixtures placed in an architectural linked model need to be replicated in the electrical model while maintaining their exact positions, the correct tool is Copy/Monitor.

This Revit feature allows the electrical designer to copy elements—like lighting fixtures—from a linked model into their project, while establishing a monitoring relationship between the original (architectural) and copied (electrical) instances.

From the Autodesk Revit MEP User’s Guide – Chapter 55 “Multi-Discipline Coordination” (pages 1349–1357):

“Use the Copy/Monitor tool to copy MEP fixtures from an architectural model into an MEP project, and monitor them for changes.”

(Revit MEP User’s Guide, p. 1350)

“To copy fixtures from a linked model:

Click Collaborate tab ➤ Coordinate panel ➤ Copy/Monitor ➤ Select Link.

Select the linked architectural model in the drawing area.

Click Copy and select the lighting fixtures to copy.

Click Finish.Revit MEP copies the fixtures to the current project and establishes monitoring relationships.”*(Revit MEP User’s Guide, p. 1356)

Behavior and Benefits:

The copied lighting fixtures maintain the same location, orientation, and type mapping as in the linked model.

Any changes (move, delete, or modify) made by the architect in the linked model will trigger a coordination review in the electrical model.

This ensures accurate positioning and easy coordination between disciplines.

“When you select a copied fixture in the current project, the monitor icon displays next to the fixture, indicating that it has a relationship with the original fixture in the linked model.”

(Revit MEP User’s Guide, p. 1357)

“If copied fixtures are moved, changed, or deleted in the linked model, Revit MEP notifies the engineers of the changes during Coordination Review.”

(Revit MEP User’s Guide, p. 1357)

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 Revit Electrical, Demand Factors are applied through Load Classifications to compute an Estimated Demand Load rather than simply summing connected loads. The documentation states: “You use demand factors to adjust the rating of the main service… Demand factors are assigned to load classifications, and load classifications are assigned to device connectors. The estimated load for a device is calculated by multiplying the load by the demand factor. … The panel schedule can also display the load for each load classification.”

In the exhibit’s Demand Factor definition (for the Motor classification), the Calculation method is By quantity with Total at one percentage selected. Two quantity ranges are defined: 0–5 items at 100% and 5–unlimited at 50%. An additional checkbox adds an extra fixed load of 5000 VA to the calculated result. (This follows Revit’s behavior of applying the selected demand factor to the connected load and then adding any specified additional load to the result for that classification.)

Panel B feeds only panels E and F. The connected motor loads downstream are:

Panel E: 20 kVA + 10 kVA = 30 kVA

Panel F: 5 kVA + 5 kVA + 10 kVA = 20 kVA

Total connected motor load on B = 30 + 20 = 50 kVA (five items).

Because five items fall in the 0–5 range at 100%, the demand factor is 100% → 50 kVA. Per the definition, add an additional load of 5000 VA (5 kVA) to the calculated result:

Demand Load on Panel B = 50 kVA × 100% + 5 kVA = 55 kVA.

Therefore, the correct choice is 55 kVA.

In Autodesk Revit, Project Parameters are used to add custom fields that apply to multiple elements within a specific project file — such as views, sheets, or schedules. These parameters allow project teams to categorize, group, and sort information within the Project Browser or within schedules without editing families or external files.

As defined in the Revit MEP User’s Guide and Revit Structure Parameters Chapter:

“Project parameters are specific to a single project file. Information stored in project parameters cannot be shared with other projects. A project parameter can be used, for example, to categorize views within a project.”

This statement directly confirms that project parameters are the correct tool for sorting or grouping views in the Project Browser.

To organize elements (like views or sheets) by building, the designer can create a custom project parameter named “Building” and assign it to the View category. Once assigned, the parameter values (e.g., “Building A” or “Building B”) can be filled in for each view.

The Smithsonian Facilities Revit Template Guide further supports this:

“View purpose is a Revit project parameter, providing a means for users to organize the many views that may exist in a BIM.”

Thus, using a project parameter allows users to add a “Building” field to each view, enabling customized browser organization (e.g., group views by Building A, Building B, etc.) without requiring shared parameters or family editing.

In Autodesk Revit MEP, conduit systems can be represented in plan views using either detailed or single-line symbology. The Single Line Symbology display setting is used for schematic or simplified representations — often in electrical riser or distribution diagrams.

The setting that controls whether conduits display in single-line or detailed form is found in the Type Properties of the conduit family, not in Object Styles or Electrical Settings. Specifically, it is accessed by selecting a conduit in the model and navigating to:

Properties Palette → Edit Type → Single Line Symbology

From there, users can define how fittings, rise/drop symbols, and conduits themselves are represented in single-line schematic mode. Adjusting this type parameter affects the graphical display for that conduit type throughout all applicable views where single-line graphics are used.

According to the Autodesk Revit MEP User’s Guide (Electrical Systems → Conduit Systems section):

“The conduit type properties define the graphical representation in single-line drawings. By editing the Single Line Symbology in the Type Properties dialog, designers control how the conduit and fittings appear in plan views.”

This parameter is especially important in electrical documentation where simplified representations are required for coordination and electrical diagrams.

In Autodesk Revit MEP Electrical Design, the System Browser is used to analyze and verify electrical systems, including panelboard connections, circuit hierarchies, and connected loads.

From the exhibit, the Properties palette shows that the selected equipment is a Lighting and Appliance Panelboard (208V MLO, 100A), named P4. To determine the parent panel that feeds Panel P4, we refer to the System Browser, which organizes the entire electrical distribution network hierarchically under the Electrical discipline.

In the System Browser on the right, under the Electrical category, we can observe that Panel P4 is nested directly under Panel P2. This organization indicates that P4 is circuited to (or fed from) Panel P2.

According to the Revit MEP 2011 User’s Guide, Chapter 4, “Electrical Systems—Using the System Browser,” it states:

“The System Browser displays electrical systems in a tree structure. Each subpanel or device listed beneath a main panel is connected to that panel through an electrical circuit. When a panelboard appears under another, it indicates the subpanel is fed from that parent panel.”

This is further reinforced in Smithsonian Facilities Revit Electrical Template Documentation (April 2021), Section 8.3 “Documentation Views,” which describes:

“Panel schedules and browser hierarchies show the distribution sequence. Subpanels appear indented beneath their source panel, indicating electrical dependency and circuit assignment.”

Therefore, by interpreting both the Revit interface and Autodesk’s documentation, Panel P4 is a subpanel connected to Panel P2, confirming that its electrical feed is assigned from Panel P2.

Final Verified Answer: B. Panel P2
