A method, apparatus and system for use in CAD/CAM design in which two or more bodies may be combined to form an assembly. When the assembly is formed, the two bodies intersect so that the volume of the assembly consists of cells containing volume common to both bodies, cells containing volume originating solely from one of the bodies, and cells containing volume originating solely from the other body. Often it is desirable to remove a portion of the assembly consisting of a cell originating solely from one of the bodies. In an existing system this can be done by selecting a face of such a cell, provided however, that said face has not been created by dividing one of the faces of the original bodies. If a divided face is selected, additional user inputs are required before the removal is executed. According to the present invention, divided faces can be selected directly by the user, without the need for further processing. The preset invention makes use of topology logs to keep track of all faces in the assembly. This alleviates the necessity for extra user input when a divided face is selected.
