Beginning with the 2024.2 version of SA, there is a direct file exchange between SA and the HHScan software. This interface supports the following scanners:
ATLASCAN Max. Wireless-enabled handheld 3D scanner for easy measurement anywhere.
MARVELScan. Photogrammetry-augmented handheld 3D scanner for wireless and targetless measurement anywhere.
Scan Data in cloud and/or STL format
Extracted Geometry including circles, grooves (rounded slots), square slots, and rectangular slots

Select Instrument > Add and choose the Hexagon Handheld 3D Scanner from the Instrument List.
Start the instrument interface using Connect button on the ribbon or Instrument > Run Interface Module and Connect . You can also pick the Hexagon Handheld 3D Scanner interface from the list of interfaces.
SA’s interface to the Hexagon Handheld 3D Scanners works through coordination with the HHScan application. All scanner control and mesh development is performed within HHScan and when the scan is complete it can be sent to SA. For this reason the interface is only used to control naming for the imported elements of the scan. This includes :
Collection. Which specifies the collection in which new data will be saved. It can be left blank to import to the current working collection.
Object Prefix. The name of the scans and geometry imported from HHScan can be prefixed with a string if a string is entered.
The instrument model used for the Hexagon 3D Handheld scanner is a simple frame. This frame represents the base reference frame for the HHScan coordinates and is used to define where the data will import. If you want the coordinates to directly align with SA the instrument should be added at the Working Frame location by editing the Add Instrument Options and entering 0 for the Increment Value. The instrument's transform can also be directly accessed from the instrument properties at any point, if needed.
The interface works by monitoring a common directory that is hard coded as follows:
C:\Users\Public\Documents\Hexagon\ZGSensor
The SA interface application takes a snapshot of the files that are already in this directory when it is opened and monitors it for new additions. As soon as new files are exported from HHScan they are detected by SA’s HHScan interface and automatically imported using the settings from the interface.
Meshes (.stl)
Point clouds (.txt)
Geometry (.txt) - Geometry import supports circles, slots and rectangles (square slots).
The Delete files after import provides a means to automatically remove these temporary transfer files if desired.
SA offers several tools are extra helpful for HHScan data analysis. These include:
An option to click on the cloud to extract features: Extract Geometry from Clouds
Options to match Nominal Features and extracted features: Detect Nominals
And a selection of helpful alignments such as: Nominal Geometry Relationships
The majority of the setup as well as the live scanning process is performed within the HHScan software. Here are the Quickstart Guides:
