Part to CAD Comparison
After a part is scanned, a supplied CAD model from the customer is compared to the scan dataset. Alignment is performed by either a best fit method or predetermined datum’s. Results are supplied in a color coded model showing deviations from CAD for both internal and external geometry.
In addition to the 3D color coded model, 2D whisker plots are also included with the results to show deviations in cross sectional slices between the scanned part and CAD model.
- Results show differences between identical parts manufactured from locations, processes, or tool cavities.
- Results show internal and external differences between the part and CAD model
- Results can show differences in 2D cross sectional slices and in 3D.
Viewing software included with your part analysisUpon 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
What types of CAD models can be imported?
Almost all types of CAD files can be imported or converted to an acceptable format for us to read.
Can the color scale be changed?
Yes. Differences from the CAD model can be sorted by a range and each range can be assigned its own unique color
What is the minimum detectable deviation from the CAD model?
The minimum deviation is equal to the accuracy of the scan
What is the smallest feature that can accurately be compared to a CAD model?
The smallest feature that can accurately be compared is two times the resolution of the scan
