ZScan Manual

The final file may be saved as a .STL file, which is a standard file used by most post-
processing software.
File Types
ZScan uses different file types to store the result of its actions.
.CLF
License file that makes ZScan functional. A specific license is
needed for each ZScanner 800.
.CST
Configuration file that contains data specific to each
ZScanner 800. The file contains calibration parameters and
information needed to create a new session
.CSF
Session file containing all the data related to a session, such as
the scans, the resolution parameters, the deleted facets, etc.
.STL
File format used to export facets.
.TXT
Text file used when exporting the positioning model
containing all positioning targets.
.OBC
File produced by AICON 3D Systems software that can be
used to import a positioning model acquired by
photogrammetry.
General Considerations
ZScan is a software that takes advantage of modern computer architecture. Almost all
operations are multi-threaded to take advantage of the dual-core processors in the
computers.
Due to constraints in Windows, there is a limit to the amount of memory that can be
allocated to a single program. That limit is set to 1.4 Go in Windows XP and to 1.6 Go in
Windows Vista 32 bits. In Vista 64 bits, the limit is function to the total amount of memory
available in the computer. For a computer with 4 Go of RAM, the limit is set to 3.7 Go.
If you go past these limits, ZScan will display an error message prompting you to reduce
the resolution or to increase the volume. It is important to note that the data in the
session is not lost. It will reappear when the volume is changed back to a more
reasonable setting. It is also possible (and recommended!) to save the session at that
point.
