As CAD models continue to become more critical information sources in the product's lifecycle, it is necessary to develop efficient mechanisms to store, retrieve, and manage larger volumes of increasingly complex data. Because of their unique characteristics, 3D annotations can be used to embed design and manufacturing information directly into a CAD model, which makes models effective vehicles to describe aspects of the geometry or provide additional information that can be connected to a particular geometric element. However, access to this information is often limited, difficult, and even unavailable to external applications. As model complexity and volume of information continue to increase, new and more powerful methods to interrogate these annotations are needed.In this paper, we demonstrate how 3D annotations can be effectively structured and integrated into a Product Lifecycle Management (PLM) system to provide a cohesive view of product-related information in a design environment. We present a strategy to organize and manage annotation information which is stored internally in a CAD model, and make it fully available through the PLM. Our method involves a dual representation of 3D annotations with enhanced data structures that provides shared and easy access to the information. We describe the architecture of a system which includes a software component for the CAD environment and a module that integrates with the PLM server. We validate our approach through a software prototype that uses a parametric modeling application and two commercial PLM packages with distinct data models.

“…A group from Laboratoire Informatique de Grenoble proposed a MPEG-7 extension called 3D SEmantics Annotation Model (3DSEAM) [4], which introduced two new 3D specific descriptors: Structural Locator and 3D Region Locator [5]. Another 3D metadata solution was developed in the AIM@SHAPE project [18].…”

The problem of metadata for interactive 3D objects has appeared very recently. It is significant due to the growing demand for interactive applications of 3D technologies. Time required to prepare such applications depends strongly on availability of reusable interactive 3D objects. Easy access to such objects can be increased by search solutions that cover not only object geometry and semantics but also object interactions. However, existing metadata standards provide tools only for general, technical and semantic descriptions of objects. The missing elements of object description solution are metadata of object interactions and an optimized query language. In our previous research we have developed an extensible solution for describing interactions of 3D objects. In this paper, we present the second missing element, a specification of a special query language that enables efficient usage of the interaction metadata.

ABSTRACT3D modeling is extensively used in many engineering fields, notably in architecture. 3D models of new buildings are built with 3D objects taken from object libraries provided by producers of real objects (i.e. windows, lifts, etc). Such libraries can also include interactive 3D objects that are not only static geometrical representations, but also behave like their real counterparts. Searching for such interactive object in a large library requires object metadata describing object interaction properties. Existing metadata standards are not sufficient for describing object interactions. In this paper a new solution for interactions metadata is presented. The new solution is composed of concepts and tools for modeling an interaction, describing different aspects of an interaction, building XML documents with interaction metadata and using information contained in these documents to search specific objects. The usage of all those concepts and tools is presented in a detailed scenario from the field of architectural modeling.
