The 3D Last System™ contains a module especially designed to accurately compare the 3D shoe last models stored in the database with 2D standard profiles commonly used by the footwear industry.

2D Profile comparison
The 2D Profile Comparison feature can be used to:

• Quickly verify that a 3D scanned last shape meets 2D standard requirements
• Easily identify areas on a last that differ from the 2D last standard profile shape
• Document the analysis in a 2D comparison quality report

A view of the 2D Standard Comparison module: the 2D standard profile selected from the integrated database of the 3D Last System is easily matched with the 3D shoe last using either manual or automatic alignment methods

2D profile alignment
A 3D last can be aligned with a toe, a shank, or a heel standard. The 2D profile and the 3D last are easily aligned using manual or automatic methods. This ensures an optimal alignment of the 3D last and standard, and thus reliable and consistent analysis results.

Graphical deviation analysis
The deviations between 2D standard profiles and the 3D last model can be displayed using a number of graphical color difference maps or whisker plots. All difference map parameters can be adjusted to optimize the information presented.

Quality reports
Quality reports can be automatically created in Word™ to rapidly communicate the results of the analysis. The reports include all relevant information and screenshots to illustrate the findings from the shoe last comparison.
