Cyclone™ CloudWorx 3.3 Tutorial – Section I
Welcome to CloudWorx 3.3 Tutorial
CloudWorx is the high-performance point cloud solution that enables you to load, render, analyze
and extract information from high-definition surveying (HDS) ‘point cloud’ data in AutoCAD ®.
The enhanced functions allow you to:

View millions of points within your AutoCAD environment

View proposed construction over existing conditions

Model proposed construction over existing conditions to meet and exceed clearances
and specifications

Create maps using AutoCAD commands
For in-depth explanations and definitions on High Definition Surveying terms, please refer to the
CloudWorx help files and user manuals. This tutorial assumes that you are familiar with AutoCAD.
Section I - CloudWorx 3.3 Basic: Civil / Survey Applications
CloudWorx 3.3 basic offers enhanced viewing functions to navigate through a point cloud. You will
be working with the database Civil_Survey.imp and the drawing Civil_Survey.dwg delivered
with this CD to see how different 3D views, sections and cut planes can be used to extract data.
These files and databases can also be downloaded from the Leica HDS WEB site. For this Section,
you will be working with a database that consists of a bridge roadway.
Section I. CloudWorx 3.3 Basic instructs how to:

Configure and Add a Cyclone HDS database

Load a ModelSpace View (3D point cloud)

Hide Regions

Clip Points to Slice

Clip Points to Section

Dimension bridge clearances

CloudWorx 3.3 Basic Tutorial – Section I
Configure Database
Databases to be configured exist on disk as files, with names ending in the .imp extension.
Before beginning, ensure that you have write permission for this database (that it is not readonly). Configuring a database establishes a connection with the Cyclone database and point cloud
engine.
1. Copy the files Civil_Survey.dwg and Civil_Survey.imp from the Cyclone CD to your
hard drive under C:\Program Files\Leica Geosystems\Cyclone\Databases.
2. Open the file Civil_Survey.dwg
3. Select CloudWorx ⏐ Configure Databases… See Figure 1.
4. Expand the Servers folder and highlight the existing server (by default this is your
computer).
5. Click the Databases… button in the Configure Databases dialog.
6. Click the Add… button in the Configure Databases on [Server Name] dialog.
7. Click the “…” button next to the Database Filename field.
8. Browse to the location of the Civil_Survey.imp database file.
9. Click Open when the file Civil_Survey.imp has been located and highlighted.
10. Click OK in the Add Database dialog.
11. Click Close in Configure Databases on [Server Name] dialog.
12. Click Close in Configure Databases dialog.

Page 4 of 7
Slices enable you to view point cloud sections in specific areas. For example, creating a slice
through the middle of the bridge would generate a profile, allowing you to dimension elevations
or model different proposed bridge routes to meet changed specifications.
In this tutorial, as may be the case for certain job, roads, bridges and other structures are not
necessarily aligned with one of the coordinate axes. In order to use Clip Points to Slice and Clip
Points to Section to their fullest capacity, AutoCAD coordinates can be temporarilly aligned to
the User Coordinate Systems (UCS). Creating additional viewports is also recommended. In this
exercise, we will:

Switch to user difined coordinates that are aligned with our bridge

Create two different viewports

Create viewports (AutoCAD commands)
1. Create two horizontal viewport using AutoCAD’s View | Viewports | Named
Viewports
2. Click in the upper viewport to activate it.
3. Select View | 3D View | Right
Switch to user-defined coordinate system (AutoCAD commands)
1. Click in the lower viewport to activate it.
2. Set the “Tut1 Rotate” named UCS as the current UCS. Your two views should look like
Figure 5.
Figure 5. Front view (top); new UCS (bottom)
Page 5 of 7
You are now ready to Clip Points. In Clip Point to Slice, two parallel planes are defined. Only
those points between these two planes are displayed.
1. Select Clip Point Cloud | Slice | Y Axis
2. Place the two clip planes as shown in Figure 6.
Clip plane one

3. Your viewports should now look similar to Figure 7.
4. Your viewports are now set up to dimension bridge clearances or elevations using
AutoCAD dimensioning commands. See Figure 8.
Figure 7. Clip plane views
Figure 8. Bridge clearance dimensions
Page 6 of 7
Clip Points to Section
Similar to Clip Points to Slice, Clip Points to Section enables you to view point cloud sections
in specific areas; your points, however, are viewed only on one side of defined plane. In this
exercise, you will cut a road cross-section in order to dimension the sag low point of a powerline.

Fit Pipes
In this section, you will create pipe centerlines. From these pipe centerlines, distances can be
measured and dimensions added. CloudWorx is able to fit a cylinder object to a point cloud or
multiple clouds based on a pick point or fence. This can be used to generate a piping run
centerline, or to obtain a tie-point coordinate. You have three options when fitting a pipe to the
point clouds:

Cylindrical cone object (ACIS solid)

Centerline (line or line string)

interfering points by hiding all non-interfering points.
6. Set the maximum Interference Tolerance to “0.15m” and click the Check button.
The interfering points are displayed in white.
7. Re-route the pipes so that they no longer interfere against the as-built point clouds.
When delivering a DWG file created using CloudWorx to an end-user who does not have CloudWorx, you
should first “purge” the DWG to remove all references to CloudWorx objects that may be stored in the
DWG. To do this, select CloudWorx Purge, then save the DWG with a different filename.
When delivering a DWG file with an IMP database to an end-user, the end-user will need to configure the
database on their computer before the clouds can be loaded. When loading the DWG file, CloudWorx
looks for the database name stored in the DWG on the local SERVER.

Engineering Best Practices
CloudWorx for AutoCAD
Using the CloudWorx Clash Manager System
Working with As-Built High-Definition Survey Data in Autodesk AutoCAD
Introduction
This document provides step-by-step instructions for using the Clash Management System
in CloudWorx Pro for AutoCAD. This powerful tool facilitates engineering design directly in a
point cloud with only limited or no as-built 3D modeling. Clash Manager is specifically
designed for industrial retrofit projects; therefore, this will be the focus application of this
document. However, many other industries can also benefit by using this tool.
It is assumed that the user has a good understanding of AutoCAD, CloudWorx for AutoCAD,
and has experience with retrofit engineering for industrial facilities. CloudWorx Pro for
AutoCAD Version 3.3 and higher is required.

Leica Engineering Best Practices - Clash Management in AutoCAD
CloudWorx Work Process Options
There are several options available for the engineer to effectively apply HDS technology in
AutoCAD. During the course of a project, a variety of work processes will be used and not
used. Engineers should use the options that best address their immediate task. The goal is
to use the processes that deliver the desired results with the least possible cost and effort.
Work process options:
1. Scan Measuring – Measurements can be taken between cloud points, cloud points and
3D objects, or individual point cloud coordinates can be displayed. In the comfort of the
office, needed site measurements can be quickly and accurately retrieved to validate a
new design concept or idea.
2. Designing Directly in the Point Cloud – Designing directly within a scan cloud is a
powerful way to route and engineer new piping, trays, ducts, structures, platforms, etc.
Using raw unprocessed scan data is an excellent way to quickly create an interferencefree design at the lowest possible cost.
3. Model on Demand – Modeling on demand is a process where users selectively model
small discrete areas from scan clouds – with heavy emphasis on the word “selectively.”
All solid modeling is limited to small distinct areas or items of immediate interest, e.g.,
objects around a specific piece of equipment, tie-ins, miscellaneous steel, nozzles,
connection points, etc.
4. As-Built Model Validation – CloudWorx for AutoCAD is a great way to quickly validate
the as-built accuracy of an existing 3D model. This procedure can be performed on a
previously created AutoPLANT 3D model or 3D plant models imported from another
external system. The model is directly compared to the scan cloud. Any deviations
from reality are corrected, and additions are made where necessary.
5. Complete 3D Intelligent As-Built Model – This is the traditional project work process
used by other as-built technologies, such as Photogrammetry. This process entails
creating a complete catalog based 3D as-built model from the point cloud, which can be
used for interactive engineering design and asset management.
6. 3D Surface Modeling – Leica Cyclone is another powerful way to model 3D objects
using simple unintelligent primitive representations. After which, the Cyclone COE file is
imported directly into AutoCAD. One example where this option can benefit is a piping
system covered by insulation, which conceals catalog details. This is a valuable
alternative when insulation cannot be removed and surface information is all that is
needed for visualization and clashing.
No single work process is effective for every situation. Selection should be based on the
specific task. It is never a good practice to rigidly assign a single set of work processes for
an entire project. Selecting the best work process is based on the following high-level
criteria: 1) What are the required deliverables? 2) What is the objective for the particular
task? 3) What is the most cost effective option to best achieve the desired objectives?

Recommended Clash Management Work Process
Presented below is a recommended step-by-step process for using the CloudWorx Clash
Manger in Autodesk AutoCAD:
1. Open AutoCAD – Open the AutoCAD drawing with the 3D objects to be interference
checked. Clash Management works only on AutoCad and MicroStation MDL.
CloudWorx works with some of the most popular AutoCAD based 3D engineering
design and visualization programs in the industry, such as Bentley AutoPLANT,
COADE CADWorx, and CAE Plant4D. (Note: 3D ACIS Solid export is required when
using Bentley AutoPLANT)
2. Load Point Cloud - Open a CloudWorx ModelSpace View and load the desired point
cloud in the display. All points in the database ModelSpace will be used for clashing.
Limit Boxes, Cutplanes and Hide Regions will not affect the result. (See Figure 1)
(The sample DWG and Database used in this document are
ClashMgrDemo2_ACAD.dwg and ClashMgr_Demo2.imp.)
Figure 1 – 3D process pipe line in AutoCAD with a CloudWorx as-built point cloud loaded
Page 3 of 14
3. Open CloudWorx Clash Manager – Go the menu item CloudWorx |
Interference | Clash Manager… or open using the CloudWorx toolbar.
(See Figure 2.)
Figure 2 – CloudWorx Interference Toolbar
Figure 3 – Clash Manager Toolbar
Note: The Clash Manager is a modal dialog that must be either closed or exited in
order to enable AutoCAD operations.
4. Creating a New Project – If this is the start of a new project, then in the Clash
Manager dialog, select the menu item File | New Project. This will automatically
open the New Project dialog. (See Figure 4.)
Figure 4 – Starting a new project
Note: The first time the Clash Manager is opened, the new project dialog is
automatically opened.
In the New Project dialog, enter the Project Name, File Name, Clash Tolerance and
Cluster Distance. Using the default Clash Tolerance is recommended. The Cluster
Distance is the distance used to distinguish an individual clash cluster. The
Page 4 of 14
recommended default clash cluster distance is 300mm (12 inches). (If you often find
that multiple clashes should actually be a single clash, then increase thr Cluster
Distance. Conversely, if single clashes should be multiple clashes, then decrease the
Clash Distance.)
Regarding the File Name entry, a browse button “…” at the end of the File Name
field is provided for specifying the file name and path. Press Create to create a new
project and Cancel to cancel the operation. (See Figure 5,)
Figure 5 – CloudWorx New Project (Units of inches shown)
5. Opening an Existing Project – Previous Clash Manager Projects can be opened at
any time for review or additional processing. This is done by selecting the Clash
Manager menu item File | Open Project. A dialog will appear to allow you to
browse to the desired path and file.
6. Reduce Point Cloud Density to Level 4 – Before starting clash processing, it is
recommended that you reduce the point cloud density to Level 4. All points are still
used for processing, however, there will be a significant increase in clash processing
speed. This is accomplished by first Closing the Clash Manager dialog using the Red
X in the upper right corner, or using the clash Manager menu File | Close. (Note:
File | Exit terminates the Clash Management session.) Then select the menu item
CloudWorx | Point Rendering | Point Density Level 4, or use the CloudWorx
Toolbar. Reopen the Clash Manager after reducing the point cloud density.
7. Interference Settings – In Clash Manager, press File | Interference Settings.
This opens the Interference Settings dialog. Verify or adjust the settings as desired.
These parameters are used during clash processing.
(See Figure 6.)
Figure 6 – Interference Settings dialog
8. Clash Processing – In the Clash Manager interface, select Tool | Process or press
the Process button on the toolbar. This will temporarily close the Clash Manager
interface and put the user in object selection mode.
Page 5 of 14
Pick individual objects or use the fence selection capability to select objects for clash
processing. When the selection is complete, press Enter to begin the clash process.
The processing time required depends on the number of objects being processed and
the total number of points in the ModelSpace ScanWorld. A progress bar rapidly
appears and goes away on the AutoCAD bottom status bar, which indicates
processing is in progress. When complete, the Clash Manager dialog reappears with
all identified Clash records listed. (See Figure 7.)

Note: The fields displayed in the Clash Manager interface can be customized by the user in
the MS Access database. Also, this can be done within the seed file, so it will apply to all
created projects. The column titles shown above are the default field settings for the
interface.
11. Processing Additional Objects – New objects can be added to the database at any
time. To add new objects, repeat the procedures noted in items 9 and 10. Clashes
that have already been detected will not be duplicated, if previously analyzed objects
are selected. However, if a previously checked object was deleted and replaced, the
old clash “Process Results” will show “Missing” and a new clash record will appear in
its place.
12. Verifying Records – To verify the current status of existing clashes, in the Clash
Manager list simply select the records of interest and select the menu item Tools |
Verify, or press the green check button on the toolbar. To speed up the processing
time it is a good idea to set the point density to Level 4. The Process Results
indicates the latest status of Clashing, Cleared, or Missing. (See Figures 9 and 10.)

(The object for Clash 1 was deleted and the object for Clash 2 was moved so the clash was no longer present)
13. Show All and Hiding Clash Records – In order to protect data integrity, clash
records cannot be deleted. However, since for various reasons records may need to
be removed from view, the Hide check box and Show All toggle are provided. To
conceal clash records from view, place a check in the Hide Record check box and
uncheck the “Show All” control, which is menu item View | Show All. To reveal all
hidden clash records, recheck the “Show All” control.

17.Suggested Work Flow:
a. Create Initial Design Model – Create the initial 3D design model using your
engineering application in AutoCAD. As-built 3D modeling can be kept to a
minimum, thereby, minimizing project cost and design delays. The
CloudWorx Pipe Fitting and Flange Work Point tool can be useful for
determining pipe and equipment tie-ins.
b. Create a Clash Management Database and Initial Design Validation At any point begin using the CloudWorx Clash Management System to
validate that the design is interference free.
c. Identify Clash Types – Using the Clash Manager zoom and limit box
feature, identify the source of each clash record. Based on what is
determined, pick the appropriate Clash Status and Type.
d. Tag Field – Use the Tag field if a custom tag is to be used for sorting or
filtering. This field is also useful for indicating who is responsible for
removing the clash, when “Assigned” is designated in the Clash Status.
e. Comment Field - Use the comment field to briefly note the source, such as
“Pipe_1234 / Steel_Brace (Re-Route)” or “COL_A13-Valve_Handle (Rotate
Handle)”, etc. (See Figure 19.)
f.
Add New Objects and Reprocess – Continue adding new design objects
and reprocess all objects as necessary. Do not be concerned about
reselecting previously clashed objects. As long as the object is not deleted
and replaced, CloudWorx knows about the previous clash and will not
generate a new record.
g. Verify Records – At any time, select one or all records to be clash checked.
The clashing objects must be visible. The “Process Results” column indicates
the current status of the clash.
h. Print Working Reports – As needed, print reports to provide to the
engineers and design management. Also, at any time, a “History Report” can
be printed providing details concerning any Clash Status modification.
i.
Repeat – Repeat this process until the design is complete and all clashes
have been resolved or approved.

About the HDS Best Practices Series
The value of having a virtual digital and dimensionally-correct as-built data cannot be
overemphasized. There isn’t a more accurate, faster, safer, or more cost effective way to
take field measurement than HDS. Design decisions are quickly made with confidence and
dimensional constraints are rapidly determined using CloudWorx or Cyclone; all in the
comfort of the office, without additional site visits. HDS is a powerful visualization tool to
assist both design and concept validation. If executed correctly, the engineer can expect
outstanding results on complex brown field projects. Performance data has shown rework
costs as low as 0.1% to 0.2% of TIC (Total Installed Cost); historically rework could be
expected to be as high as from 6% to 12% of TIC. Design decisions are validated fast,
efficiently, and with confidence in your AutoCAD application
High-Definition Surveying™, or HDS, is the information modeling process starting point
for industrial facilities, civil infrastructure, buildings and many other industry domains.
HDS, from Leica Geosystems provides the complete solution including both systems and
pointcloud engineering software, to engineers, project managers, designers, and
constructors, who need to collect, visualize, manage, and extract digital information from
point cloud data representing as-built conditions of complex engineering projects. This
paper as part of an engineering best practices series provides effective workflow solutions
that leverage existing work practices with other engineering tools and solutions to efficiently
increase productivity and maximize return on investment as you apply HDS on your next
project.
