When OpenCASCADE returns triangulation data via BRep_Tool::Triangulation(), it also returns a TopLoc_Location parameter that represents the transformation from the triangulation's local coordinate system to face coordinates. The existing code retrieved this location but never applied it to vertex coordinates, causing some STEP models to display with misplaced or distorted geometry.
