Last Preparation

Input from CAD/CAM systems or from the Scan Handling Module typically need further processing before it can be used as a basis for measurement, comparison and export to various third-party systems.

Automatic curve detection

A number of curves and landmarks are automatically identified on the 3D last model. For example, the system can extract a center line drawn manually on the physical shoe last. These curves are important to identify the different parts of a last such as the inner/outer side, the sole etc.

Manual curve adjustment

In order to ensure optimal precision, the user has the possibility to manually adjust the detected curves and landmarks.

Last alignment

Automatic or manual alignment of the last in 3D space to ensure that all 3D lasts are systematically aligned according to their toe and heel height. This eases measurement and comparison performed in other 3Shape last modules.

Profile extraction

Various 2D section profiles can be extracted from the 3D last. Profiles are important in order to identify last characteristics and can be exported for use in external last design applications.

Last parts extraction

The system divides the 3D last into several 3D models based on the curves and profiles detected in the preceding steps. The parts include inner, other and bottom side of the last.
