Autodesk RVT_ELEC_01101 Practice Test Questions Answers

In Autodesk Revit’s Electrical discipline, when electrical components such as panelboards are hosted incorrectly (for example, Panel B hosted to Panel A instead of a wall or level), the hosting relationship must be corrected by reassigning the work plane or host. This is essential because hosted electrical elements depend on the geometry or level of their host for placement, alignment, and coordination.

According to the Revit MEP User’s Guide (Chapter 45 “Work Planes and Element Hosting”):

“If a hosted element is placed incorrectly or the host has changed, use the Edit Work Plane or Pick New commands to redefine its host or work plane.”

Here’s how these two tools apply:

1️⃣ Pick New (Option A)

Located under the Work Plane panel on the Modify tab, this command allows you to select a new face or host (e.g., a wall, ceiling, or floor) for the existing component. It effectively reassigns the element’s host without deleting or recreating the element.

“Use Pick New to specify a different face or surface as the host for a component that was incorrectly placed.”

2️⃣ Edit Work Plane (Option E)

This command lets the designer redefine the reference level or named work plane to which an element is associated. For hosted electrical equipment (like lighting or panels), this ensures the object references the correct structural or architectural surface.

“To correct hosting errors, open Edit Work Plane from the Modify tab, and assign a new named plane, level, or face.”

Incorrect Options Explanation:

B. Edit Mounting value – changes only how the panel is mounted (e.g., recessed or surface), not the host itself.

C. Move command – repositions the element but does not change the hosting relationship.

D. Edit Host value – the “Host” parameter is read-only; it cannot be edited directly.

Thus, the correct methods to rehost Panel B from Panel A to the correct wall or work plane are through Pick New and Edit Work Plane, ensuring proper association and maintaining system connectivity.

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.

In the exhibit, the Label Parameters for the electrical device tag are configured as follows:

A white background with black text AI-generated content may be incorrect.

This setup determines how the tag will display in Revit when applied to any device. Specifically:

The Panel parameter (P203 in this case) will be shown first.

A “/” separator follows because it’s assigned as the suffix for the Panel parameter.

The Circuit Number (2,4) is displayed immediately after the slash, with no extra spaces or line breaks.

Since the Break column is unchecked, the values will appear on one continuous line, not split across lines.

Revit documentation for tag creation confirms this behavior:

“When defining label parameters in a tag family, the Prefix and Suffix fields control text that appears before or after the parameter value, while the Break checkbox controls whether the text wraps to a new line.”

Therefore, when the tag is applied to a receptacle on panel P203 and circuit 2,4, the final formatted text will be:

P203/2,4

This corresponds exactly to option B, where the panel and circuit appear on the same line separated by a slash, with no spaces or line breaks.

Discipline: Common

Type of Parameter: Yes/No

When an electrical designer is developing a panelboard family in Autodesk Revit and wants to control the visibility of an element—such as a clearance zone (typically used for equipment maintenance space, NEC 110.26 compliance, or access areas)—the correct method is to create a Family Parameter with a Yes/No (Boolean) value under the Common discipline.

According to the Revit MEP User’s Guide (Chapter 44 “Creating and Modifying Families”):

“Use a Yes/No parameter to control the visibility of geometry or symbolic lines in a family. When checked, the geometry displays in the project; when unchecked, it is hidden.”

This visibility control is typically applied to reference geometry such as safety clearance volumes or working spaces around electrical panels. These geometries are modeled within the family environment and linked to visibility parameters that the designer can toggle on or off in the Family Types dialog.

Additionally, the parameter must be created under the Common discipline, not Electrical or HVAC, because visibility controls are not discipline-specific—they apply to all Revit element types.

“Discipline defines the context of the parameter type. Visibility parameters are categorized under Common, as they are used across multiple disciplines.”

Step-by-step setup:

1️⃣ In the Family Editor, open the Family Types dialog.

2️⃣ Click Add Parameter → Name it Clearance Zone Visible.

3️⃣ Under Parameter Type, select Family Parameter.

4️⃣ Choose Discipline: Common and Type of Parameter: Yes/No.

5️⃣ Assign this parameter to the Visible checkbox of the clearance zone geometry.

This allows the designer to easily control whether the clearance zone appears in plan, elevation, or 3D views—useful for coordination and documentation.

Incorrect Options Explanation:

HVAC, Electrical, Energy: Used for discipline-specific parameters like voltage, airflow, or load calculations.

Text or Number: Would not allow toggling visibility.

Visible (as type): Refers to linking geometry visibility, not defining a parameter type itself.

In Autodesk Revit MEP, when working with electrical circuits, Revit visually differentiates elements based on their circuit membership and active selection during the circuit editing process. In the Edit Circuit mode, the software highlights elements connected to the active circuit in full color (black), while other electrical devices not part of that same circuit appear in halftone (gray).

In the exhibit, one receptacle appears in black, while the other is shown in gray (halftone). This indicates that only one of the receptacles is currently included in the circuit being edited, while the other receptacle belongs to a different circuit or has not yet been assigned to any circuit.

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

“When editing a circuit, the components that belong to the selected circuit are highlighted in the active color, while other elements in the view appear in halftone. Devices that are not on the same circuit will not be shown as connected or editable until added to the current circuit.”

Therefore:

The black receptacle is the one actively included in the selected circuit.

The gray (halftone) receptacle is not on the same circuit and thus not active for editing.

This visual cue is Revit’s way of helping the designer distinguish between circuit connections when adding or managing electrical devices.
