Generating a drawing symbol in a drawing

摘要

In a method for automatically generating, by a CAD program, a drawing symbol (56) in a drawing (52), an attribute object (34) is created, said attribute object (34) representing an attribute (12) that signifies at least one property of at least one entity of said model (10), said attribute object (34) is associated with a model data structure (18) representing said model (10), and said drawing (52) is generated, said drawing (52) showing said entity of said model (10) at least partially and further comprising a drawing symbol (56) that represents said attribute (12). A CAD computer program product and an apparatus comprise corresponding features. The invention provides integrated support for attribute data items that relate to different types of entities of a model processed by the CAD program.
