A collaboration server is described that enables both real-time conferencing and content management Thus, client applications can connect to the server to share data and collaborate in real-time The server allows fine grained sharing of any type of content using generic shared objects (GSO) Each GSO holds one or more pieces of persistent information and defines a list of people who are allowed to access the information Each GSO also represents a persistent conferencing session, ie, if clients modify GSOs, modifications are broadcast to all the other clients on the list of the shared object if they are connected The server also manages relationships between shared objects; ie, shared objects could be contained in other shared objects or reference other shared objects

Method and apparatus for persistent real-time collaboration

There is described a system and a method for generating a metatag indicative of an attribute of a person represented in an image, the method comprising: performing a computer-based analysis of the image; identifying a feature related to the attribute of the person in the image using results from the computer-based analysis; generating the metatag based on the identified feature; and associating the metatag to the image, the metatag being thereby related to the attribute of the person.

Method and system for image and video analysis, enhancement and display for communication

Methods and apparatus, including computer program products, for providing a computer aided design (CAD) model comprising a plurality of physical elements. An analytical representation of the plurality of physical elements is generated. The analytical representation comprising a plurality of analytical elements corresponding to the physical elements. An association between each analytical element and corresponding physical element is generated such that a modification to one element can be applied to modify a corresponding other.

Synchronized physical and analytical representations of a CAD model

A system and method for converting data generated in an computer engineering design software component to an alternate format usable by a variety of alternate software components is provided. Engineering data from a project having a plurality of objects is provided. Objects are selected from the project for conversion and transportation to one of the alternate software components. The selected objects are converted to an alternate format, transported to the alternate software component and regenerated by the alternate software component in its own environment.

Method and system for converting engineering data into 3d modeling data

Methods and apparatus, including computer program products, for providing a physical computer aided design (CAD) model comprising a plurality of physical objects in a flow system. Each of the plurality of physical objects are joined at one or more physical linkages. An analytical model of the flow system is generated based on the one or more physical linkages. And one of the analytical model or the physical CAD model is automatically updated to reflect a change to the other.

Synchronized physical and analytical flow system models

The present invention discloses a method for building, defining, and storing features in an application neutral format comprising building a feature based on a feature class, wherein the feature class comprises feature geometry, feature constraints, and feature dimensions, defining the built feature as a geometric representation of an individual feature type, and storing the representation in a binary file format.

System and method for creating and updating a three-dimensional model and creating a related neutral file format

There exist numerous design intent systems that convert captured information into structured design intent while providing intent representation and retrieval. These systems woefully neglect the design intent that is present in legacy CAD such as 2D drawings and 3D models. We address the issues that arise when dealing with the capture, representation and retrieval of design intent from the legacy CAD data. A definition for design intent in the CAD domain is presented which forms the basis of the proposed approach. The approach uses a unique context-based inference system to capture design intent from legacy CAD data. A brief explanation of context is provided along with the advantages of using context for this task. The need and use of an inference system is detailed. Additionally a prototype system is implemented to address these issues from a software system point of view.

Using a Context-based Inference Approach to Capture Design Intent from Legacy CAD

Over the last two decades, the mechanical CAD industry has witnessed the development of many powerful 3D CAD software products built upon proprietary geometric kernals. The ISO 10303 STEP standard was developed, with the Application Protocol (AP 203) in particular, to provide a medium for product data exchange of lower-level geometry of mechanical parts and assemblies. A recent version, AP203 Edition 2, introduced the exchange of product data using a hybrid model containing construction history, GD&T, parameters and other high-level content. This paper presents an interpretation of the schema definitions provided under the current standard, presents a generic approach to map feature history data between CAD systems, discusses an implementation of this approach for data translation, and discusses the issues in the standard realized during this effort.
