ACU Revit flashcards
ACU Revit · Build recall with a focused review session.
32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Project file extension
- A Revit project is saved as .rvt. It contains the model, all views, sheets, schedules, and settings, and a workshared project's central file is also an .rvt stored on a shared network location.
- Family file extension
- A loadable family is saved as .rfa from the Family Editor. It holds parametric geometry and types and is inserted into projects, where each placement becomes an instance of a chosen type.
- Category, family, type, instance
- Revit organizes elements in four levels: category groups elements by discipline (Doors), family is the parametric definition, type is a size or style variant, and instance is one placed element with overrides.
- Tab key selection
- With nothing selected, hovering and pressing Tab highlights elements under the cursor, and repeated Tab presses cycle through overlapping elements so a partially hidden element can be selected.
- Synchronize with Central
- In a workshared project, Synchronize with Central saves your local changes to the central model and reloads other users' changes, keeping the shared model current for the whole team.
- View Control Bar
- The bar at the bottom of the drawing area sets view scale, detail level, visual style, sun settings, crop and reveal-hidden-elements toggles, applying changes to the active view only.
- Wall location line
- The location line sets which reference plane of a wall type follows the picked line. Options include Wall Centerline, Core Centerline, and finish or core faces, affecting where the wall sits.
- Wall compound structure
- A wall type is built from ordered layers, each with a material, thickness, and function. Core boundary lines separate structural layers from finishes, and layers can wrap at inserts.
- Wall top constraint
- A connected wall's height is driven by Top Constraint plus Top Offset. Setting Top Constraint to a level and offsetting the top, or attaching the top to a roof, controls its height.
- Sketch-based elements
- Floors, roofs, ceilings, and stairs are created from a closed sketch loop. Slope arrows or Defines Slope on sketch lines set pitch, and the sketch must close without self-intersecting.
- Roof by footprint
- A roof created by picking walls or drawing a closed plan loop; each sketch line can be marked Defines Slope with a slope value, and the roof can be attached to the supporting walls.
- Join versus cut geometry
- Join Geometry merges intersecting elements so shared edges disappear; Cut Geometry removes one solid from another. Switch Join Order changes which element's material is displayed.
- Ceiling placement
- Ceilings are modeled in a reflected ceiling plan, either by automatic placement picking walls or by sketching a boundary. The ceiling sits at an offset above its base level.
- System family
- A family defined inside the project and not saved as a separate file, such as walls, floors, roofs, ceilings, levels, and grids. Its types are edited in the project's type properties.
- Loadable family
- A parametric family built in the Family Editor and saved as .rfa, then loaded into projects. Doors, windows, furniture, and tags are typical loadable families with editable types.
- In-place family
- A family modeled directly in the project context for unique one-off geometry. It cannot be reused in other projects and is edited in place, making it less flexible than loadable families.
- Reference plane
- A named work plane in the Family Editor used to host geometry and dimensions. Labeling a dimension between reference planes with a parameter makes the family geometry parametric.
- Family parameter formula
- A formula computes one family parameter from others, for example width plus twice the frame depth. Formulas cannot reference themselves and must use compatible parameter types.
- Shared parameters
- Parameters defined in an external text file and added to families and projects, so the same parameter carries consistent data into tags, labels, and schedules across many families.
- Tag All command
- Annotate tab command that places tags on all visible elements of a chosen category in the active view, using the currently loaded tag family for that category.
- Hosted components
- Components such as doors and windows require a host wall and are deleted if the host is removed. Face-based and unhosted components do not depend on a host element.
- View template
- A saved set of view properties including visibility and graphics overrides, scale, detail level, and filters. Applying it to views standardizes how many views display the model.
- View Range
- A plan view property with Top, Cut plane, Bottom, and View Depth, each defined by a level and offset. Elements between the cut plane and bottom appear cut; deeper elements show as projection.
- Visibility/Graphics dialog
- Opened with VV or VG, it controls per-category visibility, projection and cut line weights, halftone, and detail level for the active view, and can be saved into a view template.
- Sheet viewports
- Views placed on a sheet appear in viewports with a title that reports the view name, number, and scale. A view can be placed on only one sheet at a time.
- Scope box
- A named 3D boundary assigned to views to control crop region and grid extents. Views sharing a scope box align to the same crop and grid limits.
- Revisions on sheets
- Revision clouds and tags are placed in views and tracked in the Sheet Issues/Revisions dialog. A sheet's revision schedule lists revisions whose clouds appear on that sheet.
- Schedule fields
- Fields are parameters of the scheduled category. Available fields, filters, sorting, formatting, and appearance tabs determine which columns show and how rows are grouped and totaled.
- Key schedule
- A schedule that defines a list of key values, each carrying parameter data. Elements assigned a key inherit those values, standardizing properties such as room finishes across many elements.
- Material takeoff schedule
- A schedule that counts materials and their quantities, such as concrete volume or wall area by material, computed from the model's compound structures and element geometry.
- EQ dimension constraint
- The EQ toggle on a dimension string sets equal spacing between its references. Changing one segment's value updates the others to keep the spacing equal.
- Walkthrough export
- A camera path of keyframes through the model, exported as an AVI. Frame rate, resolution, and output path are set at export, and keyframes are edited in the Walkthrough dialog.
