THREE-DIMENSIONAL GRAPHIC ANNOTATIONS HAVING SEMANTIC ATTRIBUTES

摘要

To provide CAD including topological and geometrical entities, graphical annotation information, and data structures storing non-native format semantic annotation information.SOLUTION: A computer-aided design (CAD) model and an associated method and system include topological and geometric entities, graphical annotation information, and data structures for storing non-native format semantic annotation information. Associated APIs (application programming interfaces) can include routines to return the non-native format semantic annotation information stored in the data structures associated with a native format computer-aided design (CAD) model. The APIs can include routines to identify whether annotations include data structures storing non-native format semantic annotation information, and to identify types of the annotations.SELECTED DRAWING: Figure 2
