Introduction & Exercise Files1:16
Start your Civil 3D learning journey with the introduction and exercise files, following step-by-step videos to practice, repeat, and build confidence.
Review Grading Settings3:34
Explore how to review and customize Civil 3D grading settings, including default styles, feature naming, units, and precision for grade and slope details.
Creating Grading Criteria5:19
Create a new grading criteria set for a ditch and define three criteria—distance at -6%, 4 to 1 slope to a surface, and a 3 to 1 relative elevation.
Creating Grading Styles2:51
Create a new ditch grading style by copying style, renaming it ditch, changing the display color to red in the layout tab, and adjusting the slope pattern in Civil 3D.
Creating Feature Lines5:56
Create feature lines from straight or curved segments, alignments, or AutoCAD objects to serve as baselines for gradings, then name and elevate them with transitions to the existing grade surface.
Assigning Feature Line Elevations5:11
Assign feature line elevations using the elevation editor, insert midpoints for accurate stationing, then drape lines over the surface to create intermediate grade breakpoints.
Creating a Grading6:34
Create a ditch drainage grading in Civil 3D by using feature lines, drainage criteria, and grading creation tools to generate surfaces, target lines, and a four on one slope.
Editing the Grading Elevation5:07
Edit grading elevations for a building pad with the elevation editor to create a consistent slope and constant grade. Filter grade breaks and remove redundant rows in Civil 3D.
Balancing Cut and Fill Volumes3:12
Balance cut and fill volumes using Civil 3D grading volume tools. Analyze the building pad, view red cut and green fill, and auto-balance toward zero.
Editing the Grading Criteria3:45
Learn to edit grading criteria in Civil 3D, individually or globally, using the grading editor and criteria sets to adjust distance values for ditches, detention ponds, and berms.
Simplifying a Building Footprint4:24
Learn to simplify a building footprint and begin grading a building pad in Civil 3D using stepped offset, offset gap type, elevations, a -1% grade, and fillet radii.
Grading from a Building Footprint to a Surface3:46
grade from the building footprint to the existing grade surface by creating a slope grading group, selecting grade-to-surface criteria, and applying 2:1 cut and fill slopes.
Filling Holes in a Grading with Infills2:51
Fill holes in a grading object with infills to improve volume calculations, using shoulder and pad styles via grading creation tools for areas between building pad and offset line.
Smoothing Feature Line Arcs3:44
Smooth feature line arcs by enabling automatic surface creation with a tessellation spacing of one foot to generate a more accurate grading surface.
Adjusting Grading Triangulation with a Feature Line4:04
Adjust grading triangulation by converting a polyline to a feature line, assigning elevations from slope grading with feature line surface, and flattening elevations to constant grade with intermediate grade points.
Working with Crossing Feature Lines3:37
Master crossing feature lines in Civil 3D by using selection cycling (Ctrl W) to pick lines, edit shared elevations, and create a gradual, constant-grade transition.
Conclusion & Next Steps1:41
Finish the Civil 3D grading essentials course by practicing with the exercise files to build proficiency and confidence over time, and check the Civil 3D TV YouTube channel for tutorials.

Requirements

A basic knowledge of AutoCAD commands

Description

With the help of these tutorials, you can begin modifying grading parameters, making gradings, and altering gradings to balance cut and fill volumes. In Autodesk Civil 3D, a grading has unique qualities and behaviors, just like an alignment or a surface. Like other types of objects in AutoCAD Civil 3D, grading objects have unique attributes and behaviors. The face of a grade is often defined by a base line, a target line, and multiple projection lines. Any open or closed figure might serve as the base line for your projection of the grade.

With the help of these lessons, you will learn how to balance cut and fill volumes in gradings by modifying gradings and generating new ones.

Grading settings are used to define the units for grade and slope values as well as to manage the work environment.

Numerous typical grading scenarios exist. For instance, you might often have to make grading with a 3:1 slope and a relative elevation target. You may quickly apply the same grading criteria to other gradings by creating a grading criteria with these values and saving it.

Each grading component's appearance is controlled by grading styles. You can design many styles for use with various grading schemes. You can design styles, for instance, to show various colors for cut and fill slopes.
