AutoCad Civil 3d 2026 Training Program

In this course, you will learn about Surfaces in Civil 3D. Surfaces are used in Civil 3D to model existing and proposed terrains on your Land Development projects. Surfaces can be created from a variety of 3D data, and are used for many purposes, including to display and label elevation contours, analyze slopes, and calculate earthwork quantities. To model your surfaces correctly for these important tasks it is essential to understand how to create and edit surface objects. This course is a foundational building block for working with surfaces in Civil 3D and will prepare you for tackling more advanced tasks

In this course, you will learn how to work with Parcels in Civil 3D. Parcels can be used in a variety of ways on your Land Development projects, including to subdivide property, denote land use and coverage areas, illustrate project and/or construction phasing, and for any other geometry delineation you may require. Parcels are Civil 3D objects created from CAD geometry and include extended data that can be useful for analysis, reporting, and detailing. Parcels can be subdivided into smaller Parcels using design criteria that includes minimum area, minimum frontage, setback distance, and minimum width and depth dimensions. Once you have added Parcels into your drawing files, you can perform Inverse and Mapcheck analysis, label Parcel segments and areas, and create Parcel reports

In this course, you will learn about Feature Lines, Gradings, and Grading Groups in Civil 3D, and how to leverage them to grade your designs. Feature lines are 3D objects which can be used as grading footprints, surface breaklines, and as corridor baselines. Feature Lines are used to create projection grading, or Gradings, that target surfaces, elevations, and distances. Gradings that are added to Feature Lines will update with changes made to the Feature Line. The Grading Group is a collection of Gradings and is used to create an Automatic Surface that can be used for volume calculation and balancing. Collectively, these objects can be used to grade your designs, while maintaining a fluid and dynamic 3D model.

In this course, you will learn how to create and work with alignments in Civil 3D. Alignments can be used for a variety of purposes in your design projects, including to layout a roadway design, drainage, pressure network, and construction baselines. Depending on the purpose for the alignment, Civil 3D provides many tools to layout, design, and label alignments. Alignments are a core design objects in Civil 3D and have many direct and indirect dependencies. Editing alignments with dependencies will cause a ripple effect that will keep your designs up to date. Centerline alignments can be assigned Design Criteria to keep your projects in compliance with design standards and notify when a violation occurs. The Design Criteria Files that you assign to the alignment can also be used to calculate the superelevation.

In this course, you will learn how to create and edit Profiles and Profile Views in Civil 3D. Profiles define the vertical elevations for alignments and can only exist if there is an alignment. The surface profile represents the alignment elevation when draped over a surface, and the design profile is constructed from lines and curves to set the proposed grade. To view Profiles in Civil 3D you need to use a Profile View. The Profile View has a unique coordinate system defined from the same parent alignment as the Profile. The Profile Views are used for design layout, viewing, and to illustrate profiles in your final deliverables.

In this course, you will learn about Assemblies and Subassemblies in Civil 3D. Assemblies are a cornerstone to Corridor based modeling, and can be leveraged for a variety of land development designs. Assemblies are paired with alignments and profiles to create a complex 3D corridor model that can be used for machine control grading, volumes calculations, construction plans preparation, and for many other purposes. In this course you'll be introduce to the Assembly object and learn how the "out of the box" subassemblies can be used to tailor your grading designs. This course will teach you the basics to get you started, and give you the confidence to start modeling your roadway designs.

In this course, you will learn how to work with Corridor objects in Civil 3D. Civil 3D Corridors are complex 3-dimensional grading objects used to model roads, highways, and railways. Corridors combine alignments, profiles, feature lines, and assemblies into a single dynamic object to create propose grade surfaces, calculate earthwork and pavement quantities, and produce fully labeled cross section sheets.

In this course, you will learn how to work with Sample Lines and Section Views. Sample Lines are added to alignments at specified intervals, and at key geometry points, to sample other Civil 3D data sources in your drawing for the purpose of calculation end area volumes and plotting Section Views. Section Views are the portal used to display a cross section slice of the data sources that have been added sampled. The resulting Section Views can be used to view and validate your design and to prepare final construction documentation.

In this course, you will learn how to layout, analyze, detail, and report on Gravity Networks in Civil 3D. Pipe Networks leverage the vast library of parametric structure and pipe parts to model existing and proposed water and sewer networks. Part Rules can be assigned to Pipe Network to keep you informed of any design violations, and the 3D pipe model can be used to locate interfaces or conflicts with other Pipe Networks. To size pipes and set grades for drainage design you can Analyze the Pipe Network. For more advanced hydraulic designs you can export the Pipe Network from Civil 3D in Storm and Sanitary Analysis, or the Express Tools.
