Abstract:
1. A method for modeling a topological structure, comprising: receiving in a data processing system a definition of a topological structure having a main body topology; receiving in the data processing system a definition of a first construction element, wherein the first construction element is not fused into or a part of the main body topology; receiving in the data processing system a geometrical relationship between the first construction element and an element of the topological structure, the geometrical relationship comprising a laminar edge defined by an intersection between a face of the construction element and an offset of a face of the topological structure; receiving in the data processing system a first change to the topological structure; in response to the first change, changing the first construction element in the data processing system according to the geometrical relationship; and in response to determining that the geometrical relationship between the first construction element and the element of the topological structure no longer exists and that no other geometrical relationships exist between the first construction element and the topological structure, removing the first construction element from the data processing system.
