What is "transmagic"

TransMagic is a commercial computer program that converts computer-aided design (CAD) files from one native file format to another. During the translation process, TransMagic performs “geometry mapping”, mapping from one CAD kernel to another. During the conversion, TransMagic avoids what are known as “stitching errors” by repairing geometry via techniques such as correcting slightly overlapping or misaligned surfaces, removing duplicate control points, and duplicate vertices .
