Assessing User Expectations Of Undo In A Multi-User Cad Environment, Jeffrey Eric Nuss
Assessing User Expectations Of Undo In A Multi-User Cad Environment, Jeffrey Eric Nuss
Theses and Dissertations
Undo is a command that users rely on in most software applications. Its importance in multi-user CAD is no different. However, due to its unique nature, users may have different expectations regarding how undo should behave. This research seeks to better understand users' expectations regarding undo in multi-user CAD by having users participate in collaborative design exercises and then asking them how they would expect undo to behave. In addition, users participated in a survey in which they watched 8 videos showing users interacting within multi-user CAD and were then asked about how they would want undo to behave. Based …
Associative Cad References In The Neutral Parametric Canonical Form, Daniel Robert Staves
Associative Cad References In The Neutral Parametric Canonical Form, Daniel Robert Staves
Theses and Dissertations
Due to the multiplicity of computer-aided engineering applications present in industry today, interoperability between programs has become increasingly important. A survey conducted among top engineering companies found that 82% of respondents reported using 3 or more CAD formats during the design process. A 1999 study by the National Institute for Standards and Technology (NIST) estimated that inadequate interoperability between the OEM and its suppliers cost the US automotive industry over $1 billion per year, with the majority spent fixing data after translations. The Neutral Parametric Canonical Form (NPCF) prototype standard developed by the NSF Center for e-Design, BYU Site offers …
Understanding And Addressing Collaboration Challenges For The Effective Use Of Multi-User Cad, David James French
Understanding And Addressing Collaboration Challenges For The Effective Use Of Multi-User Cad, David James French
Theses and Dissertations
Multi-user computer-aided design (CAD) is an emerging technology that promises to facilitate collaboration, enhance product quality, and reduce product development lead times by allowing multiple engineers to work on the same design at the same time. The BYU site of the NSF Center for e-Design has developed advanced multi-user CAD prototypes that have demonstrated the feasibility and value of this technology. Despite the possibilities that this software opens up for enhanced collaboration, there are now a new variety of challenges and opportunities to understand and address. For multi-user CAD to be used effectively in a modern engineering environment, it is …
Maximizing Virtual Mucax Engineering Design Team Performance, Brett Randall Stone
Maximizing Virtual Mucax Engineering Design Team Performance, Brett Randall Stone
Theses and Dissertations
Teams of design engineers are increasingly working as members of virtual teams, or teams whose members are distributed geographically and communicate mostly through electronic means. In addition, emerging multi-user (MU) applications engage complementary teams in synchronous design activities. These new MU tools are changing the way engineers work together. Together, these factors have created a new and interesting environment in which engineering design teams must function. The work presented here lays out two major themes that teams and their managers can effectively apply to organizing and managing MU teams: 1) teams can maximize their potential productivity by determining the optimal …
Neutral Parametric Database, Server, Logic Layers, And Clients To Facilitate Multi-Engineersynchronous Heterogeneous Cad, Kelly Eric Bowman
Neutral Parametric Database, Server, Logic Layers, And Clients To Facilitate Multi-Engineersynchronous Heterogeneous Cad, Kelly Eric Bowman
Theses and Dissertations
Engineering companies are sociotechnical systems in which engineers, designers, analysts, etc. use an array of software tools to follow prescribed product-development processes. The purpose of these amalgamated systems is to develop new products as quickly as possible while maintaining quality and meeting customer and market demands. Researchers at Brigham Young University have shortened engineering design cycle times through the development and use of multiengineer synchronous (MES) CAD tools. Other research teams have shortened design cycle-times by extending seamless interoperability across heterogeneous design tools and domains. Seamless multi-engineer synchronous heterogeneous (MESH) CAD environments is the focus of this dissertation. An architecture …
