Means that the data to be created is only the shape information, and the attribute information of the entire shape can be registered only slightly in the attribute information of the file. However, since it is only described as character information on a two-dimensional drawing, how to handle information that cannot be represented by a shape becomes a bottleneck. Consequently, it is necessary to create one drawing in addition to the three-dimensional shape. / CAM has been an obstacle to the spread of CAM.
