ZScan User Guide

First, make sure that you are scanning your calibration plate properly. You can also 

check for any reflective object as far a 2 feet around the plate on each side. You can 
also try to "Reset" your Configuration File by using the Default button in the 

Calibration 

Window

 
I had a "Out of memory" error and now there is no surface or facets in my session. 

Your data was not lost in the process. The new memory manager will inform you that it is 

out of memory and was not able to rebuild the surface/facets. You can set your 
resolution to a lower level and try to rebuild the surface. If this is unsuccessful for any 

reason, set the resolution to Low, save your session, restart ZScan and try to open it again. 

 
Some holes appear when I increase the resolution. 

Increasing resolution requires more data. Holes can be created if there is not enough 

data to reconstruct the surface at this resolution. 
 

My surface doesn’t appear completely when in Facets view. 
The part you are scanning may be too large or may not be centered in the scanning 

space. Make sure that your scan is properly positioned using the functions available in 

Surface view. 
 

 

Scanning Techniques Solutions 

I am not able to scan small parts. 

Smaller parts require more data. Contrast is very important for the scanner to detect 
what to scan and what not to scan. If it looks like it is not catching the surface, try using a 

background that is the same color as the part you are trying to scan. 
 

I have some trouble scanning the darker surfaces or parts of the surface. 

It is very important to adjust the laser power and shutter time according to each surface 
to scan. 

 

 
 

Miscellaneous Solutions 

I checked the option to install the plugin for Geomagic, but there is nothing under plugin 

in Geomagic. 
Make sure that you chose the right plugin for your version of Geomagic and that you 

can find the file ZScanGeomagic”X”PlugIn.dll where "X" should be your version of 

Geomagic.
