Abstract
A system, method, and computer program product for measuring wall thickness. After an internal body topology of the model is generated, the topology is traversed between wall elements to determine wall thickness.
Claims18
A method for determining the thickness of a wall of a graphic model, comprising:
- identifying a first element in a surface mesh of a model;
- projecting the first element onto a face of the model to identify a first projected point;
- determining a face normal direction at the projected point;
- searching for a second element in the surface mesh of the model, guided by the face normal direction;
- identifying the second element in the surface mesh of the model;
- projecting the second element onto a face of the model to identify a second projected point;
- and
- determining and storing the distance between the first element and the second element.
