The goals of the WWW project are to establish a central site for the latest research and software in CAD-based assembly tolerancing tools, to provide a forum to facilitate communication of new technologies and to provide a bibliography with easy access to articles and reports that deal with tolerance analysis.
Various service have already been implemented at the site. The site is still under construction with new options and improvements being added as Internet development tools become available. Currently, the site features the software and research of the ADCATS organization at BYU. An overview of the CADD application and theory is available and is followed by several 2-D and 3-D examples.
To aid in tolerance research, technical articles, papers, bibliographies and abstracts can be reviewed, studied, and copied through an FTP service. Also, to stimulate communication between researchers in this field, an electronic listserver has been implemented. Researchers can now use the listserver at this site to ask questions, help others, and to keep up to date on tolerance research.
The ADCATS web site runs on a QUADRA 950 and has 28 MB of RAM. The URL for ADCATS is "adcats.et.byu.edu".
Various software packages are used to provide the services at the ADCATS site. A brief overview and breakdown of these applications will now be discussed.
The majority of the documents available at this site were created in Microsoft Word format. Microsoft Word has the capability of saving files in an "interchange format" known as RTF. This neutral format is then used by another application called RTFtoHTML which converts the Word files into browsable HTML documents (with embedded graphics included).
Files are made available for research with a powerful search engine called "Total Research - WWW." This application will use a key word to find ALL files with references to this word. This greatly speeds up the research process. Files are made accessible in two ways: FTP and binary files. FTPd is the application used for the server FTP capabilities and DropStuff compresses files into transferable binary files.
Many graphics formats can be converted with "GraphicConverter." "MapServ" and "GifServ" are script applications which are in the process of being implemented for more esthetic presentations.
The web server is also a mail server which enables listserver capabilities. Three applications work together to provide this service. "MailShare" makes the computer a mail server. "AutoShare" provides the listserver capabilities and "Listserv" interfaces with web browsers to provide an interactive interface.
Various scripts are used to provide feedback forms which are coupled with the "Eudora" electronic mail package.
One future objective is the implementation of an interactive database interface at the web site. This will facilitate the research objectives of the project.
