“…Most related work fits into this description. According to [1]: "E-Rep [2,3] distinguishes between generated features, datum features, and modifying features; it regards a CAD model as being built entirely by a sequence of feature insertion, modification, and deletion operations. The EN-GEN Data Model (EDM) [4,5] extended STEP's current explicit entity representation by adding some predefined local features such as round and chamfer in a bottom-up approach."…”

Data exchange between different computer-aided design (CAD) systems is a major problem inhibiting information integration in collaborative engineering environments. Existing CAD data format standards such as STEP and IGES enable geometric data exchange. However, they ignore construction history, features, constraints, and other parametric-based CAD data. As a result, they are inadequate for supporting modification, extension and other important higher-level functionality when accessing an imported CAD model from another CAD system. Achieving such higher-level functionality therefore often requires a time-consuming, error-prone, tedious process of manually recreating the model in the target CAD system. Based on techniques adapted from programming language research, this paper presents an approach to exchanging parametric data between CAD systems using formally-defined conversion semantics. We have demonstrated the utility of our approach by developing a prototype implementation that automates the conversion of 2D sketches between two popular CAD systems: Pro/ENGINEER and SolidWorks. We present examples showing that our approach is able to accurately convert parametric CAD data even in cases where models were constructed using operations from the source CAD system that have no direct counterpart in the target CAD system. Although the case study focuses on 2D interoperability, our approach provides formal foundations for supporting 3D and semantic interoperability between CAD systems.

“…The hybrid semantic feature model we proposed in [1] is used to represent implicit and explicit features in order to enable history-neutral feature construction. It is intended to capture feature semantics in a textual document and support feature mapping as we will discuss in Section 4.…”

“…Compared to the static identify-and-map approach, our approach reduces the complexity of searching and mapping processes for multiple systems. The time used in this process has a linear relationship with the number of systems whereas the traditional one-by-one translation process has a factorial complexity and is difficult to manage as the number of systems grows [1]. 2.…”

Interoperable information exchange between computer-aided design (CAD) systems is one of the major problems to enable information integration in a collaborative engineering environment. Although a significant amount of work has been done on the extension and standardization of CAD data formats as well as the cooperation of CAD systems in both academy and industry, these approaches are generally low-level and narrowly targeted. Lack of fundamental study of interoperability and generic solution to this problem is the major issue. Our intention of this research is to design a solution of CAD feature interoperability as generic as possible based on a theoretical foundation of language types. In this paper, we present a fundamental model of semantic features and feature mapping process based on the type theory. We implement and demonstrate our approach for automated feature exchange between commercial CAD systems.
