Following are the additional features of this book:· Detailed explanation of AutoCAD Civil 3D commands and tools· Real-world civil engineering projects as tutorials and with step-by-step explanation· Emphasis on why and how with explanation· Tips and Notes throughout the textbook· 704 pages of heavily illustrated text · Self-Evaluation Tests, Review Questions, and Exercises at the end of each chapter
Brief Table of Contents
Points are the basic building blocks in AutoCAD Civil 3D. In civil engineering projects, points are used to identify the existing ground locations and design elements. In Civil 3D, each point has a unique number and each numbered point has properties that include information such as northing, easting, level, and description. These points can also have additional properties to control their appearance, such as point style, point label style, and layer.
Surfaces are key objects in AutoCAD Civil 3D and these are a three-dimensional geometric representation of the surface of an area of land. In Civil 3D, surfaces can be composite or volumetric that represents the difference between two surface areas, as in case of volume surfaces.
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 is no unwanted points in the design.
In a civil engineering project, an alignment object represents centerlines, carriageways, verges, highway boundaries, or construction baselines. To create and define the horizontal alignment is the first step in highway, railway, or site design process.
In AutoCAD Civil 3D, an alignment object can be drawn from a polyline or it can be created using the Alignment Layout Tools toolbar. The alignment objects can also be edited using the grips or commands in the Alignment Layout Tools toolbar.
In AutoCAD Civil 3D, the grading tools and commands enable the engineers to grade a surface by applying different criteria, such as applying slope to a surface or grade to a distance. You can then analyze the gradings and balance the cut and fill as well as volumes of a surface.
In AutoCAD Civil 3D, profiles (or long sections) are used to show surface levels along a horizontal alignment and selected surfaces. After you create a profile you can design the vertical alignment directly on it by using standard alignment tools, grips, or editors.
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 in 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 both earthworks and materials, using the Quantity Take Off tools.
Assemblies and Subassemblies
An assembly and subassembly constitutes the primary structure of an AutoCAD Civil 3D corridor model. The assembly objects contain and manage a collection of subassemblies that are used to form the primary structure of a corridor model. The subassemblies can be carriageways, kerbs, and slopes that can be added to the assembly baseline to create an assembly.
In AutoCAD Civil 3D, a corridor model is applicable for any linear ground-based feature that brings together various objects and data including subassemblies, assemblies, alignments, surfaces, and profiles.
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.
You can use pipe networks to draw 2D and 3D models of utility systems such as storm sewers, wastewater sewers, and more. 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 there is a change made to the pipe networks in plan view, the profile and section views are dynamically updated.
An object is a drawing element that maintains a relationship with other objects. For example, an alignment object is a combination of lines and curves that collectively define the location of a project component, such as the centerline of a road. This alignment can be an individual stand-alone object or parent object of other objects such as profiles and cross-sections. On editing this alignment, there will be a change in the other objects that are related to it.
Apart from alignment objects, AutoCAD Civil 3D has other objects such as points, surfaces, 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 object components such as tables, object labels, and various analysis results that are derived from the model. These object components are dynamically associated with the core model, such that if any change is made in a part of the model, these object components are dynamically updated.
AutoCAD Civil 3D software is a blend of several Autodesk solutions including AutoCAD, MAP 3D, and Civil 3D toolset along with Trimble LinkTM , Carlson Connect TM, and Leica Exchange. You can use all the traditional commands that exist in AutoCAD software and these can be accessed through toolbars, menu bars, and from the command prompt.
AutoCAD Civil 3D provides a model-centric technology at the core, that enables the entire team in a project to co-ordinate 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 give a parallel accessibility to the team members working locally or remotely on the latest updated model. As a result of this approach, a project can be managed well and the budget can also be controlled.
