System and method for analyzing modeling accuracy while performing reverse engineering with 3d scan data

A method for analyzing 3D modeling accuracy when processing 3D scan data, comprising:

• providing a collection of 3D scan data forming a model representing the shape of a three dimensional object;
• providing a CAD system being used to remodel at least one CAD part body formed from the 3D scan data;
• selecting an operation designed to manipulate one of at least a portion of the 3D scan data or at least a portion of the at least one CAD part body;
• determining a measure of loss of accuracy attributable to the selected operation;
• and
• presenting the measure of the loss of accuracy to a user.

A system for analyzing 3D modeling accuracy when processing 3D scan data, comprising:

• a collection of 3D scan data forming a model representing the shape of a three dimensional object;
• a CAD application being used to remodel at least one CAD part body formed from the 3D scan data;
• a user interface enabling the selection of an operation, the operation being one of a scan data editing operation and CAD remodeling operation;
• and
• an accuracy analysis facility, the accuracy analysis facility measuring a loss of accuracy attributable to the selected operation.
