Frequently Asked Questions

Capture 3D uses only GOM scanners and software. Thus upgrading in the future will be limited to GOM scanners. If you switch to another scanning system you will lose all your inspection macros and sequences files.
The ComScan System inspection macros are in Polyworks or GeoMagic software and your sequence files are in ComScan. Because the ComScan system supports all scanners you can upgrade to any new manufacturer in the future and preserve your inspection macros and sequence files. If you want to change your inspection software, you only need to rewrite your inspection macros.
This modular approach makes ComScan a great investment for now and the future.

No, pull out and look at your machinist scale; on one side you have 8th inch increments and on the other you have 16th inch increments. Therefore one side has twice the resolution than the other. Which side of the scale is more accurate?

The higher the resolution, the finer the detail that can be scanned. Higher resolution will lengthen the acquisition time a little and increase data storage requirements.

All scanner types can be used with Photogrammetry Target “spots”. There is no need for Photogrammetry Targets when the scanners are used with a ComScan system

White Light Scanners will need surface prep for almost all surface conditions with controlled ambient lighting.
Blue Light Scanners will need surface prep on shinny and dark surfaces with no need to control ambient lighting in a lab environment.
Laser Interferometry Scanners will need surface prep on shinny surfaces with no need to control ambient lighting in a lab environment.

3D Area Scanning Cameras (Scanners) have a larger variety of options and one of the main cost drivers for scanners is Repeatability and Accuracy. The tighter the Repeatability and the higher the Accuracy the higher the price. Using AIAG guidelines, the measurement instrument you need must have a measurement uncertainty of 0% to 30% of your smallest tollerance band and preferably less then 10%.

For Example: If your smallest tolerance for a given component is +/- 1.0 mm, then your tolerance band is 2.0 mm. The measuring instrument, scanner you need, should preferably perform at a measurement uncertainty, P/T Ratio, of 0.2 mm or less. P/T Ratio's are typically determined by Gage R&R studies
