In Revit Architecture, you can create a ______ between projects. You can also ______ CAD files and DWF markup files to a Revit project.

Listening Dimensions

A Revit feature that allows you to specify a value for a dimension as you sketch an element in a view. You specify a start point for the element, start sketching in the desired direction, type the exact dimension desired, and press Enter. Revit Architecture draws the element to the specified length. The following image shows the text box that appears when you start to type a ______.

Load

To transfer a file or a collection of information from an outside location into a Revit project. In Revit Architecture, you can ______ groups, templates, detail components, entourage, materials, families of model elements and annotation elements, and other project information.

Local File

A copy of the project file that resides on the computer system of the team member who is working on the file. When worksharing is used to distribute project work among team members, each member uses a ______ to work on his or her workset (functional area). Team members periodically save their changes to the central file so that others can see the changes and update their ______ with the latest project information.

Location Line

A vertical plane in a wall that is used for dimensioning. You create a wall by sketching the ______ of the wall in a plan view or a 3D view. You specify what to use for the ______ in the element properties of the wall: the wall centerline, core centerline, interior or exterior wall face, or interior or exterior face of wall core. In the following illustration, the green dashed lines indicate the ______ of the wall.

Lock

To secure a dimension or the location of an element so that it cannot be changed. When you select a ______ dimension or element, a ______ control displays next to it. The following drawing shows a ______ dimension.

Mark

A unique identifier that you assign to an element in its properties. You can include ______ in schedules and tag labels. For example, the following site plan shows ______ for individual parking spaces. These ______ are also listed in the parking schedule.

Markup

Comments or revision instructions from someone who reviewed a building design. When you publish construction documents as DWF files, the files can be ______ up electronically using a program such as Autodesk Design Review. Then the ______ can be linked back into Revit Architecture to display the desired changes.

Masking Region

A defined area that obscures elements in a view. ______ are useful when you are creating a model family from an imported 2D DWG file, and you need the model element to obscure other elements when placed in a view. You can also use them to hide parts of a drawing.

Massing Study

One or more masses in a Revit project. ______ allow you to explore design ideas by using shapes to conceptualize a building model. When your conceptual design is complete, you can add building elements directly to these shapes.

Matchline

A sketch line that indicates where to split a view for a dependent view, as shown.

Material

The substance of which an element is made. In Revit Architecture, the ______ assigned to an element determines how the element appears in a view or rendering. Revit Architecture includes several ______ in the default project templates, or you can define your own. You can specify the color (in a shaded view), texture (in a rendered image), surface pattern (in a projection), and fill pattern (in a cut view).

Material Takeoff Schedule

A list of the subcomponents or materials of any Revit family. ______ have all the functionality and characteristics of other schedule views, but they allow you to show more detail about the assembly of a component. Any material that is applied to a component within Revit Architecture can be scheduled.

Mirror

To reverse the position of a selected model element, using a line as the ______ axis. For example, if you ______ a wall on a reference plane, the wall flips opposite the original wall. You can pick the ______ axis or draw a temporary axis. Use the ______ tool to flip a selected element, or to make a copy of an element and reverse its position in one step. The following image shows the results of ______ and copying a door, using the center wall as the ______ axis.

Miter

A joint at a 45-degree angle, or evenly angled between the joined elements. ______ can apply to walls, wall sweeps, railings, structural floors, roof fascia, curtain wall mullions, and other model elements. When 2 walls join, you can edit the wall join using a ______ joint or other joint styles.

Model Element

An element in a building model that represents actual 3D geometry. For example, walls, windows, doors, and roofs are ______. For example, the following image shows only ______. It does not include annotation elements (such as dimensions or text notes) or datum elements (such as grid lines or levels).

Model Graphics Style

A method of displaying model elements in views. For example, you can choose to display a model using wireframe, hidden lines, shading, or shading with edges. You can specify the ______ for a view using the View Control Bar at the bottom of the Revit window.

Model Group

A set of model elements that are placed together in a building design. ______ are useful when you need to create entities that represent repeating units or are common to many building projects (such as hotel rooms, apartments, or repeating floors). The following illustration shows a ______ (highlighted in red) that has been placed in multiple hotel rooms.

Model Line

A model element that exists in 3D space and is visible in all views of a Revit project. You can use ______ to represent 3D geometry in a building design, such as cords or cables that secure a tarp. You can sketch straight, curved, arc, circular, fillet, and tangent lines. The following truss uses a ______ to represent the beam stick symbol.

Model Pattern

A graphic design that is applied to the surface of a model element. ______ represent the actual appearance of an element, such as brick coursing or ceramic tile on a wall. They are fixed with respect to the model and scale with the model.

Model Text

Text used in a building model, such as for signage. You can add ______ in a project view and in the Family Editor for families that can be represented in 3D, such as walls, doors, windows, and furniture. An instance of ______ is a model element. ______ is not available for families that can only be represented as 2D, such as annotations, detail components, and profiles. You can specify properties for ______, including font, size, and material.

Moment

The amount of rotation at an axis caused by downward force applied to a beam at a distance from its supporting members. A ______ connection is a connection that is designed to transfer ______ and other forces between a beam and its supporting members. In Revit Architecture, you can specify ______ parameters for a beam, including the ______ connection start and ______ connection end.

Monolithic Stairs

Stairs that consist of one solid piece of material, such as concrete. In Revit Architecture, you can specify that stairs are ______ in the stair type properties. You can also specify the material for ______.
