Part to Part Comparison

After two parts have been scanned, both datasets are compared together. Alignment is performed by either a best fit method or predetermined datum’s. Results are supplied in a color coded model showing deviations between each part for internal and external geometry.

In addition to the 3D color coded model, 2D cross sectional whisker plots are also included with the results to show deviations in cross sectional slices between both parts.


  • Results show differences between identical parts manufactured from different; locations, processes, or tool cavities.
  • Results show internal and external differences between both scanned parts
  • Results can show differences in 2D cross sectional slices and in 3D.

Viewing software included with your part analysis

Upon completing the analysis, a web conference is hosted by one of our experienced analysts to review the results. During that same web conference, we’ll show you how to use the supplied freeware viewing software.

  • Frequently Asked Questions

    Can the color scale be changed?
    Yes. Differences between both scanned parts can be sorted by a range and each range can be assigned its
    own unique color

    What is the minimum detectable deviation between each part?
    The minimum deviation is equal to the accuracy of the scan

    What is the smallest feature that can accurately be compared between each part?
    The smallest feature that can be accurately be compared is two times the resolution of the scan
