1INTRODUCTION
Thank you for purchasing the Sense™2 3D scanner. You can think of scanning as a sort of physical photography. By scanning a
physical object, you can create a 3D digital model. Unlike traditional photography, however, you can use the digital model to return to
the physical mode by sending the image to a 3D printer.
You can also use Sketchfab and Facebook to publish, share, and embed interactive 3D les you create.
The Sense 3D scanner gives you the ability to observe a scene in three dimensions and then translates the observations into a 3D
model. You can then use various Geomagic applications to translate the scans into information such as:
• Identication of people and their body properties
• Classication of objects such as furniture, packages, and so on
• Measurements such as size and volume
• Location of walls and oor

3SENSE SCANNER SETUP
Unpack and set up your scanner and scanner software before you get started with the basics of scanning.
WHAT'S INCLUDED
The box contains the Sense 3D scanner with attached USB cable and the Quick Start Guide.
Remove the scanner from the box and plug the USB cable into your computer.
DOWNLOAD THE SENSE SOFTWARE
Navigate to http://www.3dsystems.com/shop/sense/downloads, and follow the instructions to complete the software download and
installation.
RUN THE SENSE SOFTWARE
When you installed the Sense software, a shortcut was created on your desktop. Use the shortcut to open the application.
NOTE: If the scanner is not connected to your computer, a message will state "Device not connected." Plug the USB
connector for the scanner into the USB port on your computer.
You will then be prompted to activate your Sense 3D scanner.
ACTIVATE YOUR SENSE SCANNER
If you do not have an activation code, click on Get activation code. Once you have your activation code, you can enter it into the
activation dialog box. Click Activate scanner to complete the activation.

4SENSE SCANNING TIPS AND TRICKS
Many practices that ensure good photography also apply to scanning. Use the following tips to get the most from your scanning
experience:
LIGHTING
• Different lighting conditions can affect the quality of a scan. The Sense for Intel RealSense 3D scanning application is designed for
indoor use, and will work less than optimally in direct sunlight.
• Position your subject in a way that will cause as little shadow as possible. You may need to add additional light to reduce shadows.
• You’ll get the best results if the light shines with equal intensity over the subject being scanned. Areas that are less illuminated
might show up too dark in the scan, and areas that are over-illuminated might show inaccurate colors.
• If you scan in darkness, the scanner will capture geometry but not color.
POSITIONING
• Position your subject so that you have 360° clearance around it.
• In preview mode, make sure that the whole object you want to scan shows inside the green box on the screen. This helps ensure
that you capture the entire object while scanning.
• Keep the scanner within its optimal distance range of the subject, which is approximately 0.45m - 2m (18” - 6.5 ft.).
MOTION
• Multiple passes on the object are allowed. If there are gaps in the scanned data after a single pass, continue scanning to try to ll
the gaps.
• If the 3D view turns white as you’re scanning, it is because the object being scanned is too close to the scanner. To correct the
view, move the object out to at least the minimal dened distance of 0.5m (20 inches).
GENERAL
• Before scanning a small object or one without a lot of distinct features (such as a standard coffee mug), add some items around the
object. This will help the scanner maintain tracking by giving it more to lock on to.
SENSE NAVIGATION
The following shortcut keys, mouse controls, and touch gestures can be used to navigate around the workspace:

5HOW TO SCAN
This section will give you all of the details relevant to scanning, editing, and sharing your model.
SCAN MENU BAR
A
File View opens the les you have saved within the application. It presents you with thumbnail previews of each of the OBJ
les.
B
Log In to or Log Out of your Sketchfab or Facebook account.
C
Options Menu brings up a menu to adjust various parameters of the application. See details below.
D
Help displays the Help menu. For details, refer to the section “Help Menu” on page 9.
E
Exit/Minimize the application.
SETTINGS MENU
The Settings Menu provides the following options:
• Show Target Ring - toggles the display of the target ring on your screen; it can be useful for keeping the scanner pointed at the
center of the object being scanned.
• Object Recognition - attempts to automatically identify and highlight the object you are scanning. The scan data will automatically
be cropped to remove everything but the identied object.
• Show Wireframe - Toggle on and off wireframe view.
• Show Color - Toggle display of the model’s color.
• Flip Scan View - Toggle between portrait and landscape orientation. (only available on the SR300, handheld camera)

ADVANCED SETTINGS
The Advance Settings dialog boxes, available from Settings Menu > Advanced Settings..., give you access to several options
pertaining to the Scan Data and Interface.
Scan Data
• Geometry Resolution - move the slider from low to high to adjust the resolution of the scanned image. The higher values will
consume more processing power and memory, and may cause delays in the scanning process.
• Scan Volume - this parameter controls the size of the area (cubic volume) that will be scanned if a specic object is not being
tracked.
• Brightness Correction - toggle automatic brightness correction on or off.
• Use Track Assist - turn on if you intend to use the track assist images that are provided in the Sense Track Assist document, avail-
able from the Help Menu. Refer to the section “Sense Track Assist” on page 9 for an overview.
Interface
• Countdown - toggle on or off the scanning countdown that appears after beginning a scan.
• Prompt for Image Capture - this prompt appears when scanning an object. Every 30 degrees, the application will prompt you to
pause your motion so that the object resolution will be optimally captured. Toggle this setting to show or hide the prompt.
SENSE TRACK ASSIST
When an object has relatively uniform geometric features, such as a cylinder or sphere, the lack of unique geometry can cause the
camera to lose tracking.
In these cases, we have provided a document with printable images and instructions that will assist you in obtaining the best possible
scan results. You can access the Sense Track Assist document from the Help Menu.
HELP MENU
The Help menu provides the following options:
• About - shows information about the application.
• Language - select your preferred language. You will need to restart the application for this change to take effect.
• User Guide - displays a PDF of the User Guide.
• Scanning Tips - open the Best Practices for 3D Scanning document.
• Acknowledgments - displays information about copyrights and contributors.
• Check for Update - see if there is an update for your software.
• Play Video - play the introductory video.
• Track Assist - open Sense Track Assist document. Refer to the section “Sense Track Assist” on page 9 for an overview.

SCAN SETTINGS
The application provides the following choices in order to optimize your scan:
Object: any item other than a person.
Head: a person’s head and shoulders
Body: a person’s full body
THE SCANNING USER INTERFACE
Data within the Scan Volume
When an object is contained inside the specied volume, it will appear in full color. Objects outside this range are grayed-out and fade
into the background.
Object Recognition
Using the Object Recognition option, available in “Options Menu”, helps to stabilize tracking, increase mesh quality, and sets the
trimming plane.
OBJECT HEAD BODY
Objects inside the
specied volume
show in full color
Targeted objects will have
a green box around them
Unrecognized objects will
not have a box around them

113D Systems, Inc.
Data Build-up
During scanning collected data will appear as “green” snow over top of the object or person.
Tracking Indicators
If you move too fast or too slow while scanning, a message box will appear instructing you to move slower and the collected scan data
on screen will turn yellow.
Lost Tracking Indicators
Occasionally, the software will lose tracking of the scanned object. This occurs when you move too fast while scanning or when the
object falls outside of the camera’s view. This will cause the collected data on screen to turn red. Focusing the camera back on a
previously scanned area will regain tracking.

123D Systems, Inc.
