The National Design Repository project was begun in 1995 as an effort to serve researchers in engineering design, manufacturing process planning and geometric and solid modeling. The Repository is a collection of public domain computeraided design data from a variety of sources and vendors. This data includes solid models and CAD files, computer-aided(More)
In the following, we describe our vision of a collaborative engineering environment, the Collaborative Design Studio, consider issues and questions relating to the effective design and evaluation of such systems, and describe proposed studies for evaluating and evolving the current environment. This work is being undertaken at the Geometric and Intelligent(More)
A key obstacle in the growth of unmanned vehicle operations is the number of operators required to supervise and control an unmanned vehicle. New unmanned vehicle CONOPS call for an individual or small groups of tightly integrated operators to control several vehicles simultaneously. This push to invert the classic operator/vehicle ratio cannot be achieved(More)
This paper describes recent results from the National Design Repository Project ( The Repository is a growing digital library of publicly available Computer-Aided Design data from a wide variety of application domains (Mechanical, AEC, GIS, etc). The long-term goal of this project is to create a flexible infrastructure for(More)
We discuss a vision of and work in progress on a collaborative engineering environment, the Collaborative Design Studio, being developed at the Geometric and Intelligent Computing Laboratory at Drexel University. This works seeks to integrate Computer-Aided Design (CAD) and communication tools through automatic extraction and embedding of design context(More)
This paper presents an approach to applying evaluation-guided research techniques to the implementation and evaluation of collaborative environments for distributed design and manufacturing. In particular, we are focusing on the use of Engineering Design Knowledge Repositories: digital storehouses of design data and metadata that are creating during the(More)
