Abstract: A computer-implemented method and system reduces size of a data structure of a computer-aided design (CAD) model. Given a CAD model formed of a plurality of modeling elements, the method and system provide one or more geometric entities defining modeling elements of the CAD model. The geometric entities have corresponding graphical entities configured to display the CAD model. For each modeling element, the method and system determine visibility of the modeling element and produce a reduced data structure by storing in the structure graphic data representing the graphical entities and geometric data of only certain ones of the geometric entities determined as a function of visibility of the corresponding modeling elements.
