Patent ID: 7149677

Claim:
A machine-executed method for comparing computational geometry system translations, comprising: extracting point cloud data from geometric data in a pre-existing source geometric model and pre-existing source geometric data related to one of a surface, an edge, a curve, and an alternative geometric entity in the source CAD system; generating translated target geometric data in a target CAD system using the pre-existing source geometric model, the translated target geometric data comprising point cloud data extracted from geometric data in the translated target geometric model and translated target geometric data related to one of a surface, an edge, a curve, and an alternative geometric entity in the target CAD system; comparing the point cloud data extracted from geometric data in the pre-existing source geometric model with the translated target geometric data related to one of a surface, an edge, a curve, and an alternative geometric entity in the target CAD system, and reversely comparing the point cloud data extracted from geometric data in the translated target geometric model with the pre-existing source geometric data related to one of a surface, an edge, a curve, and an alternative geometric entity in the source CAD system to identify a discrepancy between the translated target geometric data and the pre-existing source geometric data; and after comparing, visually displaying to a user the identified discrepancy in the translated target geometric model or source geometric model if the identified discrepancy is beyond a pre-determined distance tolerance set by the user.
