Main Interface

The Grading Pro tool is accessed through the DiRoots tab in Civil 3D. The main interface provides a comprehensive workflow for surface grading operations, from initial setup to final application.

Overview

The main interface serves as the central hub for all Grading Pro operations, allowing you to:

• Add Surface Grading - Primary function to modify and create new surfaces
• Access Setup Grading - Configure sections and section placements
• Select Reference Path - Define the section reference path for section placement
• Configure Feature Lines - Set up feature line settings
• Modify Profiles - Adjust grading profiles as needed
• Find and Define Related Gradings - Locate and configure grading types
• Apply Grading - Execute the surface modifications

Main Interface Components

Add Surface Grading button

The ‘Add Surface Grading’ button is the primary function that initiates the surface grading process. This button serves as the entry point for creating or modifying grading surfaces and provides access to all grading configuration options

Surface Selection And Creation

After adding a surface grading, choose existing surfaces to modify from your Civil 3D project or create a new one:

Section Reference

Define the section reference path for section placement by selecting the appropriate path type. The Section Reference is the main path that defines the origin of the section placement in the 3D space.

Reference Path Type Options

After clicking on the column button, the user is prompted to select a reference path type, you can choose from the following options:

• Alignment + Auto Corridor Feature Line
  Use both an alignment and a auto corridor feature line as the reference.

• Only Auto Corridor Feature Line
  Use only the automatically generated corridor feature line as the reference.

• Feature Line
  Use any existing feature line as the reference path. The stations on this objects are defined from the creation origin of the feature line.

• Corridor + Auto Corridor Feature Line
  Use the corridor and the corridor feature line as the reference.

Select the option that best fits your scenario. The interface will display these options in Civil3D, as shown in the image below:

Grading Type Name

Assign a custom name to your grading configuration for easy identification and reference later. This name helps you quickly recognize and manage different grading setups within your project.

Section Selection

Select your section setups from the configured section definitions

For detailed information on section configuration, see Section Setup.

Section Placement Selection

Select your section placements that define where sections are applied

For detailed information on Section Placement Setup, see Section Placement Setup.

Feature Line Settings

The Feature Line Settings panel allows you to configure how feature lines are created and managed as part of your grading design. In this section of the interface (see image below), you can:

• Select/Create Output Site – Specify the target site for new feature lines.
• Assign Feature Line Style – Choose the style to apply to generated feature lines.
• Layer Assignment – Set the layer for output feature lines.

Accessing Grading and Section Setups

The main interface provides different ways to access configuration and setup options:

• Grading Setup - Click the “Grading Setup” button (with gear icon) in the upper-right section to access overall grading configuration options
• Current Section Setup - Click the gear icon next to the “Section” column header to access the current selected Section Setup
• Current Section Placement Setup - Click the gear icon in the “Section Placement” column to access the current selected section placement settings

These setup options allow you to customize the grading behavior and section configurations before applying them to your surfaces.

Apply Grading

Execute the surface modifications with your configured settings:

• Check Gradings to apply - Check the settings the user want to execute
• Apply Grading - Click on the ‘Apply’ button will set the grading on the checked grading setups.
• Results Confirmation - The status column shows the status of each executed grading
