Dynamic turning curves 

The CGS dynamic turning curves have 

proved to be one of the best and 

most useful tools for driving 

simulation through cross-roads, 

roundabouts or narrow streets. 

By selecting a standard EU or userdefined 

vehicle (car, bus, truck with 

trailers or special vehicles), you can 

simulate the driving and see: 

� tyre-paths, 

� movements of trailers or 

� colour the driving area. 

Simulation paths can be defined by 

selecting Civil 3D horizontal 

alignments, edges (polyline entities) 

or by interactive driving (using arrow 

keys). 

This extension includes a special 

function for a driving simulation in 

profile, which enables you to examine 

the designed heights of garage 

entrances or similar.

Cross-roads and 

roundabouts 

The cross-roads (junctions) geometry 

extension includes functions for 

designing and editing compound 

curves, cross-roads islands and 

roundabouts. 

Complex geometry can be solved in 

seconds instead of hours in 

accordance with national and 

international road design standards. 

Functions are also available for 

creating roundabouts. These solve the 

geometry for perpendicular and nonperpendicular 

connections to the 

roundabout circle and offer various 

parameters for setting the geometry 

precisely according to the design 

requirements. 

The geometry of cross-roads and 

roundabouts is created with Civil 3D 

horizontal alignments, which allows 

full integration with Civil 3D projects. 

All basic elements of junctions are 

dynamic. If the user changes one of the 

intersecting alignments or one of the 

road edges, all corresponding junction 

elements will be updated automatically. 

Islands are improved dramatically. New 

types of triangular islands have been 

added. 

With the new user interface, the user 

can control all island parameters at any 

time during the development process. 

In addition, better integration with Civil 

3D is achieved. Geometry can be drawn 

as alignments or polylines. 


Traffic signs and horizontal 

signalization 

With this extension you can rapidly 

add traffic signs and horizontal 

signalization to your design. 

Hundreds of different traffic signs are 

available, compatible with national 

road design standards. 

You can define the position of traffic 

signs along the road, change their

position and extract traffic sign data 

including station (chainage) and 

distance from the centreline into 

special tables. 

Additionally, useful functions for 

placing horizontal signs, such as zebra 

crossings, triangles, arrows and other 

pavement signs are available. You can 

define different colours and calculate 

the areas for colouring/shading the 

paved areas. 

A new group of commands to draw, 

edit, delete, and refresh longitudinal 

road markings has been added to the 

2009 version. 

The new version brings new and 

improved functionality for inserting 

traffic signs and creating reports. 

Traffic signs are dynamically 

connected to the selected alignment. 

If an alignment is changed, attribute 

values in traffic signs and extract 

tables are updated automatically. 

Signs are inserted on separate layers 

for each axis, so signs for each axis 

can be turned on and off. The user 

can also now enter station (chainage) 

and perpendicular distance to define 

traffic sign location. 

Traffic sign reports are now dynamic. 

If the user deletes a traffic sign or if 

an alignment is changed, the report is 

now automatically updated to reflect 

the latest state of traffic signs in the 

drawing. The report is now generated 

with AutoCAD table element. Editing 

of the report is therefore much 

simpler. Users can select their own 

report template. New commands to 

copy, edit and move traffic signs have 

also been added. 

This extension includes a new 

command that draws ghost islands 

within a closed polygon. Users can 

choose a ghost island for both one 

way and two way traffic. Special 

commands are available for editing 

existing ghost islands or erasing all 

the entities that make up a ghost 

island. 

Horizontal alignments 

The horizontal alignments extension 

offers two additional methods for 

defining and editing road centreline 

geometry and improves some of the 

behaviour of Civil 3D horizontal 

alignments. The new methods 

brought to Civil 3D by this extension 

are a polygon method and the so 

called “stick” method. 

Supported languages:

Both of these methods are compatible 

and can be used in combination 

during design. You can generate a 

polygon element from any Civil 3D 

alignment and use it for efficient 

horizontal alignment editing with 

better flexibility than by using 

standard Civil 3D editing commands 

alone. 

Using these two methods you can 

avoid undesirable horizontal 

Checking Road design 

standards 

By selecting appropriate road design 

standard and road categories, the 

program examines the Civil 3D 

horizontal alignments, vertical 

alignments and cross-falls / 

superelevations. 

It verifies if their parameters conform 

to the selected standard or not. The 

result is a report list, where all critical 

or non-compliant elements are 

highlighted. 


Road lanes and widenings 

This extension brings a missing “lane 

functionality” to Civil 3D and the 

possibility of easily and accurately 

calculating lane widening along 

horizontal alignments. Lanes can 

represent road lanes, pedestrian 

footpaths, cycle lanes, grass areas etc. 

Typical cross-sections are predefined 

according to various national road 

design standards, enabling automatic, 

quick and accurate selection of lanes 

and their widths. 

Widenings in curves are a common 

practice in Europe due to limited 

construction space. CGS Civil 3D 

extensions support various national 

road design standards in order to 

correctly calculate and define the road 

widths. CGS lanes are connected to 

Civil 3D horizontal alignments for 

automatic updating. 

alignment solutions, such as short 

tangents, or non-maximum radii. This 

extension also provides flexible 

definition and editing of compound 

spirals. 


Road lanes and widths are displayed 

in table form and are saved as Civil 3D 

assembly objects in order to properly 

generate and display cross sections 

and a 3D corridor of the road. 

CGS Extensions 2009 includes new 

commands to create or edit lane 

widening. Widening can be used to 

open a new lane for slow vehicles and 

to create additional lanes crossroads. 

Widening can be anchored to a 

specific station (chainage) or it can be 

anchored to a specific point in a 

drawing. The advantage of this 

anchoring method is that any 

widening will remain in the same 

position when axis elements are 

edited. Various combinations of 

widening elements (arc-arc, parabolaparabola, 

arc-line-arc, arc-lineparabola, 

…) and parameters (speed, 

length, first and second R) are 

possible. All widenings are updated 

automatically when you edit 

alignments or polylines to which 

widenings are attached. 

Bus stops can be drawn either in 

tangents or curves. Even if they are 

drawn in curves they are constructed 

out of straight lines and arcs. The user 

can choose from a set of predefined 

bus types or can add a new bus 

definition. All values are stored in an 

XML file. Bus stops can be anchored 

to a specific station (chainage) or can 

be anchored to specific points in the 

drawing. A bus stop will also move 

dynamically with its corresponding 

element. 


Cross-falls / 

superelevations 

As with the calculation of widenings, 

cross-falls will also be calculated in 

accordance with national design 

standards. 

This extension not only brings the 

ability to calculate cross-falls for 

different road categories and for each 

lane, but also offers tools to easily 

modify cross-falls in specific crosssections. 

The calculation of cross-falls may be 

very complex. Results are displayed in 

table form and saved as 


superelevations directly in to the 

corresponding Civil 3D alignment. The 

user can use special subassemblies 

built in CGS Extensions in order to 

properly generate and display cross 

sections and the 3D corridor of the 

road. 

One of the goals in creating this 

extension was to offer the user a 

friendly and easy to use cross-fall 

functionality. 

� The Cross-fall command supports 

design speed changes at any station 

(chainage) along the alignment. 

Horizontal visibility 

analysis 

The horizontal analysis extension 

calculates and draws a visibility splay 

polyline. By definition, a visibility splay 

is the line from a driver's eye in the 

middle of the driving lane to the next 

point in the middle of the same lane 

at the required stopping distance. The 

user can also modify the parameters 

of existing visibility analysis and the 

visibility splay will get updated 

according to the new parameters. 

Road design Reports 

This extension generates text / 

numeric outputs of the most 

significant road design data: 

horizontal alignments, vertical 

alignments and cross-sections. 

Data is read directly from the Civil 3D 

objects and saved into txt, xls or html 

files. The output format is designed 

according to local road design 

standards in Europe and may vary 

from country to country. 

Current version of CGS Extensions 

support the following reports: 

� Surface data by sections 

� Stakeout of points along the 

alignment 

� All major geometry data of the 

road: horizontal elements, vertical 

elements, cross falls, width 




Railway design 

Cant design / 

alignment/ export tool 

The Cant Design CGS Civil3D 

extension is the first native Civil3D Rail 

extension that works completely on 

Civil3D objects (alignments and 

profiles). With this extension Cant 

Design for conventional rail track and 

high speed rail track is possible within 

Civil3D. The Cant design tool supports 

linear and non linear spiral types plus 

linear and non linear vertical 

transitions in order to precisely 

compute cant values in spiral sections. 

The Cant Design extension 

compromises Design Cant, Edit Cant 

and Export Cant (Geometry) tools. The 

Design Cant tool enables the user to 

design correctly applied cant values 

based on a specific country cant value 

definition (applied cant constant, cant 

deficiency value). Cant Settings enable 

a variety of cant parameter value 

definitions in order to complete the 

Cant Design work quickly and 

accurately 

The Edit Cant tool enables further 

editing of applied cant values on 

selected alignments, sections of 

selected alignment, rotation point 

definition on selected alignment 

entities, manual applied cant 

definition and many others in order to 

enable use of design cant in difficult 

geometry conditions. 

The Export Cant tool supports various 

export data formats for applied cant 

values. In addition to applied cant 

values, a complete rail geometry 

export to Plasser&Theurer WinALC 

data format is also supported. This 

format includes the data of alignment 

geometry, its corresponding profile 

geometry and applied cant values 

calculated by the Cant Design tool. 

This export to WinALC format enables 

fast and precise data transition for 

specialized tamping machinery. 

The Cant Design extension enables 

accurate cant design work and data 

export within Civil3D. It is a cost 

effective and time saving tool for 

railway design using Autodesk 

Civil3D. 


Hydraulics & Hydrology 

HH sewer networks design 

HH sewer networks design is a CGS 

Civil 3D Extension for the HH 

(hydraulic and hydrologic) design of 

sewer networks. 

This program calculates waste and 

storm water discharges and the 

corresponding diameters of Civil 3D 

pipes. Functions are provided for 

defining, viewing and editing 

catchment areas, HH calculation and 

viewing of the resulting pipes. 

The program uses the rational 

method for the calculation of storm 

runoff. It supports both constant and 

time-dependant rainfall intensity 

(user-specified or using the Reinhold 

equation). In the latter case, the 

corresponding intensity is found 

separately for each pipe based on 

pipe's concentration time. The 

wastewater discharge can also be 

added for the computation of the 

combined sewer systems. 

For the computation of pipe 

diameters, the user can select 

between three resistance equations. 

The pipe diameter is changed 

automatically during the design 

process and is always taken from the 

active Civil 3D pipe catalogue. The 

results are shown in tabular form, 

where various computation-related 

HH reports 

HH Reports are a collection of 

additional reports and tables for pipe 

systems. Currently it contains a 

manhole prefabrication list command. 

This command creates a table with 

the size and connection data 

necessary for the prefabrication of the 

manholes. 


parameters are displayed. This 

content can be copied to other 

programs like MS Excel for further 

processing. 


Excavations 

This tool calculates excavations 

between any level line and terrain 

line. 

The first step is to specify ditch 

characteristics (single ditch, double 

ditch, ditch with formwork ). Then the 

user arranges and specifies attributes 

of the table report and area definition 

(selected feature profile, surface 

layer). The final result of excavation 

calculations is a table report for 

material quantities. 


General 

Raster Manager 

The raster manager is a group of 12 

commands for raster manipulation 

(attach/detach, load/unload, 

show/hide). In addition to inserting a 

raster image by selecting one or more 

files, a command is provided for 

inserting all rasters that cover the 

current display and are contained in 

the selected folder. 

Using the toolbar, it is then easy to 

turn them on and off or to 

attach/detach them based on selected 

point(s), crossing line(s), windows or 

polygons. 

The example on the left shows how to 

turn on rasters with the crossing line 

method (red line). By using this 

method, the function will turn on (or 

off, if they've been previously turned 

on) the rasters that the line crosses. 

Similarly, the rasters can be 

manipulated by the point(s), window 

or polygon method. 

Conclusion: Raster Manager, provides 

easier manipulation of raster images 

within AutoCAD Civil 3D. 


Tools 

The tools are a collection of useful 

functions that further enhance the 

functionality of Civil 3D. 

The plotbox utility enables you to 

define drawing borders at the proper 

size and automates the generation of 

layouts for plotting. 

The cut and fill hatching utility helps 

you to generate appropriate hatch 

lines and colour areas between four 

points or two selected bordering 

alignments / polylines. You can set 

various parameters for the hatch 

density and colours. Hatch patterns 

react dynamically to changes in the 

bordering alignments / polylines. 


Best fit / alignment 

The Best fit-alignment CGS Civil 3D 

extension is a very useful tool for 

railway and road reconstruction and 

maintenance projects. It enables the 

user to derive a best-guess centreline 

alignment from a given survey data 

set. Input data can either be a 

polyline or a chain of Civil 3D COGO 

points or AutoCAD blocks sampled at 

the centreline of an existing road. 

Additionally, input data can consist of 

two sets of points or two polylines 

representing the left and right road 

edge. The result is a Civil 3D 

alignment with or without transition 

curves. The calculation is done based 

on a regression analysis where the 

total error is minimized.
