Station and Offset

The Station and Offset tool calculates station and offset of selected points according to selected reference alignments. This enables the creation of report tables with station and offset data.

Extract Blocks from Points

This tool helps you extract blocks that mark Civil 3D COGO points.


Add/Subtract Surface

The Add/Subtract Surface tool calculates new surface by adding/subtracting elevation values of selected surfaces.


This powerful grading functionality lets you design various spatial entities with different grading criteria allowing you to save the templates. Edit the source geometry and review the results in real time.

Copy Gradings

The Copy Gradings command lets you copy existing grading definition with all components to a new reference geometry.

Join Gradings

This command joins two gradings with similar definitions by creating linear transitions between them.

Split Grading

The Split grading command splits grading at selected point allowing you to edit each new part individually.


Join Alignments

The Join Alignments command will join selected alignments and optionally alignment profiles.

Create Offset Alignments

Select alignment and create multiple offset alignments in a single instance. You can choose from predefined sets of offset alignments or create and save new lane configurations yourself.

Create Alignment from Feature Line

Create Civil 3D alignment from feature line or 3D polyline element. You can also create a Civil 3D profile if your feature line / 3D polyline has assigned elevations.

Polyline to LandXML

With this function you can save LandXML file directly from polyline, 3D polyline or feature line entity


Create Offset Profile

Civil 3D does not allow you to create offset on Civil 3D profile. With our tool you can create a Civil 3D profile offset polyline by defining offset value or through point.

Label Feature Line in Profile View

With this command you label feature lines that were projected in profile view. The labels will show exact feature line slopes/grades not the projected slopes/grades.

Create Multiple Profiles

This command creates profiles and profile views for multiple alignments. You can select alignments single surface that will be used in all profiles as a reference surface for profile creation.

Edit Profile Views

This command allows users to select multiple profile views and edit them all at one time. You can change the profile views style, bands, and adjust the reference elevation.

Create Reverse Profile

Civil 3D already has a function to reverse the direction and stationing of an alignment, but not the profile. The Create Reverse Profile command allows you to reverse the direction of the Finished Ground Profile after the alignment direction is reversed.

Profile Tangency Check

This command analyzes the selected alignment or profile and detects and labels tangents without curves.


Corridor Section Editor

Corridor section editor allows you to modify corridor by editing the cross sections in section views. It also enables linear transitions of parameters between two stations.

Corridor Spreadsheet Editor

Corridor Spreadsheet Editor is powerful corridor editing tool that allows you to edit corridor in an MS Excel like editor. It provides possibilities for various kinds of workflows like editing regions, targets and reconstructing corridors in new drawings.

Label Assemblies

It is handy to label assemblies with their names so you can quickly find the ones you are working on.

Assembly Report

Create an AutoCAD table of a corridor displaying all the different baseline and regions. This report will show each assemblies start and end stations along a corridor.

Create Multiple Corridors

With Create Multiple Corridors you can select multiple alignments, set your corridor style, and target surface to create multiple corridors at once. The tool also allows you to join them into a single corridor.


Pipe Editor

This tool enables you to edit multiple pipes. Use the intuitive user interface to define how pipes should behave and apply changes to the whole pipe set.

Structure Editor

Making changes to structure and connected pipes is tedious in Civil 3D. This tool enables you to browse through structures with ease and edit the most important pipe and structure parameters.

Set Structure Reference

This tool allows you to quickly set alignment and surface as a reference to your pipe network. Reference can be set manually, from structure to structure or for the entire pipe network. 

Structure Report

This tool creates an Excel report of all selected structures and includes all parameters of structures and connected pipes.

Swap Multiple Parts

This tool allows you to swap multiple structures and multiple pipes at the same time.

Level Service Network

This tool allows you to set elevations and grades for all your service lines going into the main without using the structures at connection points.

Create Structures from Points

This tool creates pipe network structures from selected COGO points. Command can be used to automate a pipe network creation process from existing surveyed data.

Convert Lines to Pipes

This tool converts selected line, polyline or arc entities to Civil 3D pipe objects. Newly created pipes are automatically connected to the existing structures, which are located at the selected entity start/end point or vertices.

Create Points on Structures

This tool creates COGO points on selected structures, setting rim or sump as point elevation.

Pipe Elevation

Display pipe elevation and depth at any location along a pipe. Optionally a user can insert a structure or COGO point at a specified location along the pipe. This command will allow the insertion of a structure in profile view.


Check Utility Crossings

This tool calculates crossings between utility segments (gravity and pressure network pipes), inserts COGO points at crossing locations and marks crossing elevation difference.

Pipe Depth Analysis

This tool creates report of pipe depths. The results are presented in table or graph.
