Civil 3D ACP key terms

A named collection of display and behavior settings that controls how a Civil 3D object such as a point, surface, or alignment appears and behaves in drawings and labels.

A DWT file that stores default styles, layers, settings, and object defaults so new project drawings start with consistent standards instead of Civil 3D's out-of-box defaults.

The folder designated in Civil 3D options where data shortcut projects are created and stored, allowing multiple drawings to share project objects.

A mechanism that publishes selected objects from a source drawing so other drawings can reference them read-only, keeping design data centralized and coordinated across a project.

A read-only copy of an object, such as a surface or alignment, brought into a drawing through a data shortcut rather than being copied and edited locally.

The command that converts a referenced data shortcut object into a locally owned object in the current drawing, breaking the live link to the source drawing.

The assigned geographic or projected coordinate zone that defines how drawing units map to real-world locations, affecting point import, surface accuracy, and data exchange.

A defined pattern that tells Civil 3D how columns of text in an external file correspond to point properties such as number, northing, easting, elevation, and description.

A rule set that matches point description codes and automatically applies a point style, label style, layer, and optional scaling or rotation when points are created or imported.

A named, rule-based collection of points that share properties; it controls display, labels, and which points are exported or used by other objects.

A style that determines the marker symbol, size, and display characteristics used to represent a point object in plan, model, and profile views.

A line of data added to a surface that forces triangle edges to follow ridges, edges of pavement, or flow lines, improving the surface's accuracy along those features.

A surface built from an irregular network of triangles connecting elevation points, used to model existing or proposed ground terrain.

A closed polyline or other object that limits where a surface is built or displayed, such as an outer boundary or a hide boundary over a building footprint.

A comparison surface created from the elevation difference between two existing surfaces, used to compute cut and fill quantities between them.

A three-dimensional polyline-like object with elevations at each vertex that can carry design information such as a curb or shoulder and can be used to build or modify surfaces.

A container that organizes grading objects created together, managing their common properties, surfaces, and the volume calculations generated from the graded areas.

A design method where minimum standards such as sight distance, curve radius, and superelevation are stored in a criteria file and checked automatically as geometry is created.

A horizontal path object representing a road centerline, edge, or other route, defined by tangents, curves, and spirals and used by profiles, corridors, and sections.

A vertical representation of elevations along an alignment, showing existing ground and proposed design grades, curves, and vertical tangents.

The graph object that displays one or more profiles along an alignment, including grid, axis annotations, and bands of data.

A strip attached to a profile view or section view that reports station, elevation, offset, or other computed values beneath the graphic.

The banking of a roadway around a curve, defined by transition and runout parameters, that counters centrifugal force and is applied to alignments and corridors.

A reusable cross-section framework made of subassemblies attached to a baseline, defining the shape and dimensions of a corridor's typical section.

A parametric component such as a lane, shoulder, curb, or ditch that is attached to an assembly and builds geometry in a corridor.

A three-dimensional model built by sweeping an assembly along one or more baselines, generating surfaces, feature lines, and material volumes.

A station range within a corridor baseline where a specific assembly is applied, allowing the typical section to change along the route.

The alignment, profile, and station range that a corridor follows; corridors may have a main baseline plus additional baselines for intersections or ramps.

A surface generated from selected corridor links or feature lines, used for volume calculations, grading, and display of the designed ground.

A graph showing the cut cross-section of existing ground and design at a given station along a sample line, with optional data bands.

A line placed across an alignment at a station that defines where section views are cut and where material volumes are computed.

A library of pipe and structure parts, organized by part family, from which specific sizes are selected and inserted into a pipe network.

A named subset of catalog parts that limits which pipe and structure sizes and materials are available for a given pipe network.

A collection of pipes and structures, such as storm or sanitary lines, that share a network name and can be analyzed for flow and interference.

A command that tests pipes and structures against other objects, such as another network or a surface, and reports locations where they clash or have insufficient cover.

Quantity Takeoff, a Civil 3D feature that extracts counts, lengths, areas, and volumes from objects using pay item formulas for cost estimating.

A named set of material definitions, such as cut, fill, and pavement layers, used to compute volumes between surfaces and along sample lines.

A surface created from the elevation difference between a base and comparison surface, used to visualize and quantify cut and fill depths.
