Automatic trimming of geometric objects in CAD/CAM systems |
摘要 |
A method and apparatus for automatically trimming a geometry that is formed by the spatial intersection of geometric model primitives created on a computer aided design (CAD) system. In one embodiment of the present invention, an automatically trimmed representation of the geometry is determined while retaining the geometric model primitives used to determine the automatically trimmed representation. In another embodiment, the automatically trimmed representation is determined based upon a concept of sense that can be assigned to each model primitive, or inferred for each model primitive. In a further embodiment, the automatically trimmed representation is determined based upon a boolean evaluation of the spatial intersection of the geometric model primitives.
