INTRODUCTION to AutoCAD Civil 3D 2022

AutoCAD Civil 3D is a powerful Building Information Modeling (BIM) tool that is used for designing, analyzing, and documenting engineering projects such as land development, transportation, and environmental projects.

This software includes various sets of tools for designing a civil engineering project along with the tools from other Autodesk products such as AutoCAD and Map 3D. It also has interfacing application such as Trimble Link™ , Carlson Connect™, Infraworks, and Leica Exchange for transferring and converting data set into Civil 3D environment. These tools can be accessed through toolbars and Ribbon provided in the software interface. Civil 3D also supports the traditional commands that exist in AutoCAD software to invoke various tools. These commands are executed using the command prompt in the software.

AutoCAD Civil 3D 2022 provides a model-centric technology at the core that enables the entire team in a project to coordinate and work on a single updated model. Data sharing is conducted through various approaches ranging from Xrefs and data shortcuts to integrated data management controls. These approaches help team members to work in parallel, connected locally or remotely, on the latest updated model. As a result, a project can be managed well and the budget can also be controlled.

BASIC FEATURES OF AutoCAD Civil 3D

AutoCAD Civil 3D features a range of design and analysis objects within its three-dimensional dynamic engineering model. These Civil 3D objects include points, surfaces, parcels, alignments, profiles, and gradings. All objects in this model have a hierarchical interaction mechanism with each other. This mechanism ensures that modifications carried out in one object are truly reflected in other objects that are connected to it.

A Civil 3D object is a drawing element that maintains a relationship with another Civil 3D objects. For example, an alignment object is a combination of lines and curves in a horizontal plane that collectively defines the location of a project component such as the centerline of a road. This alignment can be an independent object or it can be a parent object of other Civil 3D objects such as profiles and cross-sections. If you edit this alignment object it will result in the change of other related Civil 3D objects.

Civil 3D has other objects such as points, surfaces, alignments, profiles, sites, parcels, gradings, corridors, assemblies, and subassemblies. All these objects have a designated hierarchy that can be viewed in an interface component called the TOOLSPACE palette.

AutoCAD Civil 3D also features various other object components such as tables, object labels, and the analysis results that are derived from the model. These object components are associated with the core model and they can be dynamically updated so as to reflect any change made in the core model.

Some of the various objects required to create a Civil 3D model are discussed next.

Points

Points are the basic building blocks in AutoCAD Civil 3D. In Civil 3D, points are coordinate geometry points and are also known as the COGO points. In a civil engineering project, points are used to represent the existing ground locations and design elements. A Civil 3D point object is different from the AutoCAD point object. An AutoCAD point merely displays the location of an object. A Civil 3D point has a unique identification number and properties such as northing, easting, elevation, and description. These points can also have additional properties to control their appearance such as point style, point label style, and layer.

Point Groups

The point groups allow you to group the COGO points together. The groups are created by using the point objects that have similar characteristics. This helps you to control the overall appearance of the points. Point group objects make it easy to change the point number, point style, and other properties of a large number of points.

Surfaces

Surfaces are key objects in AutoCAD Civil 3D. They are the three-dimensional geometric representation of a land terrain. In Civil 3D, you can calculate a composite volume surface that represents the difference between two surface areas.

The surfaces are created using points, point files, DEM data, existing AutoCAD objects, contours, breaklines, and boundaries. You can also import the information regarding the surfaces from LandXML, TIN (Triangulated Irregular Network), and DEM (Digital Elevation Model) files.

In AutoCAD Civil 3D, you can perform various surface analyses to show different height ranges, slopes, and watershed areas. This is done to ensure that there are no unwanted point in the design.

Alignments

The alignment objects in civil engineering projects represent the geometry of features like the pipeline, road, canal, railway, or construction baselines in a horizontal plane. Creating and defining the alignment is the first step in the design process of highway, railway, or other engineering projects.

In AutoCAD Civil 3D, an alignment object can be created from a polyline or by using the Alignment Layout Tools toolbar. The alignment objects can also be edited using the grips or commands in the Alignment Layout Tools toolbar.

Profiles

The profiles (or long sections) are used to show surface levels along a selected horizontal alignment using the specified surfaces. After creating a profile in Civil 3D, you can design the vertical alignment directly on it by using standard alignment tools, grips, or editors.

Profile Views

The profile views are used to represent the graph lines which form the grid along which the profile is plotted. One profile view object can be used to represent multiple profiles. Profile view object also includes data bands. Data bands can be used to display additional information about the profile view.

Assemblies and Subassemblies

Assemblies constitute the primary structure of an AutoCAD Civil 3D corridor model. The subassemblies are the building blocks for creating an assembly. The assembly objects are composed of subassemblies. The assembly forms the primary structure of a corridor model. The subassemblies can be carriage ways, curbs, and slopes that can be added to the assembly baseline to create an assembly.

Corridors

A corridor represents a path such as a road, railway, or canal. The horizontal and vertical geometry of a corridor is defined by the alignment and the profile.

The corridor objects are created along one or more baselines (alignments). These are then created by placing a 2D section (assembly) at incremental locations along the baselines and by creating matching slopes that reach a surface model at each incremental location. The corridor models can be edited on the basis of sections.

Parcels

The parcels represent any closed boundary that is spatially referenced to a geographical location. However, the major use of parcel is to represent a tract of land which could be a lot in a subdivision. Parcel can also be a water body or even a lot in a given site which is termed as site parcel.

Grading

In AutoCAD Civil 3D, the grading tools enable the engineers to grade a surface by applying different grading criteria. On applying grading to a surface, you can analyze the grading and balance the cut and fill volumes of a surface.

Sections

In AutoCAD Civil 3D, sections or cross-sections provide a view of the terrain that is cut at an angle across a linear feature such as a proposed road. The sections are cut across the horizontal alignments at specified station intervals. These sections can be plotted individually for a specified station or as a group for a specified range of stations, depending on the purpose of a plot. You can generate the section volumes from a design for earthworks and materials using the Quantity Take Off tools.

Pipe Networks

You can use pipe networks to design the utility system such as the storm and wastewater system which carry fluids under the effect of gravity. The pipe networks are created from design catalogs and can be edited in plan views. You can also display the pipe network parts in profile and section views. Therefore, if a change is made to the pipe networks in plan view, the profile and section views are dynamically updated.

Pressure Pipe Networks

In Civil 3D, the pressure pipe network consists of objects that are used to design a pipe network that carries fluids under pressure, such as water supply network. In this category, various tools are provided to design the network in plan and profile layout. Similar to pipe network, the pressure pipe network is created from the parts that are available in a parts list. This parts list is derived from the AutoCAD catalog which is a master collection of various available parts.
