The focus of this paper is the Rapid Prototyping (RP) process, presented and educated using novel 3D interactive, browser readable multimedia. Rapid prototyping methods range from hand crafted objects that are often animated, to CNC (Computer Numerical Control) machined parts, to CAD 3D models, to physical clay models that are hand or robot crafted in the automotive and aircraft industries. Rapid prototyping has many other integrated physical and intellectual domains, including software. This

Furthermore, to some extent we discuss our object / component knowledge documentation architecture and offer real-world examples, mostly during the software demonstration part of this paper, of this industry/academia sponsored R&D effort. orders of magnitude ([1], [2], and [3]). The primary delivery mechanism for the above outlined system, includes case based education and knowledge documentation of design efforts, including extensive rapid prototyping to avoid unwanted designs. At the beginning, the key value of this process is cost savings, customer satisfaction and revenue growth. As soon as the factory, or organization understands the benefits of web-enabled enterprise processes that share resources, applications and data, the opportunities for further waste reductions and growth are even more dramatic. This is the stage when the e-business gradually becomes a network of connected lean and continuously knowledge documenting/ distributing/ knowledge managing and learning businesses. On a parallel tract, in education, the created CBL (Case-based Learning) Library is an effective method supporting outcome-oriented quality problem solving and assessment because it forces both the student as well as the tutor to focus, and then create new wealth, and follow US ABET (Accreditation Board of Engineering and Technology in the USA), and European educational principles. As our validation results, and the over thirty supporting and collaborative enterprises, the academic institutions, and the thousands of undergraduate and graduate students clearly indicate, our solution can be applied to satisfy a large variety of knowledge documentation and learning, as well as hi-tech product marketing needs. Class Architecture, Creative Innovation and Needs Analysis There are several definitions of design knowledge management. In our view none of them can fully grasp this very complex research issue, therefore, for our practical purposes design knowledge management attempts to succeed by combining correlating data and information produced by information processors, such as computers, embedded 'machine, versus human-smart' devices, and others, as well as creative, innovative, sensing and reasoning human beings (who still drive the show...), in our case experts in integrated design and manufacture. The concluding fact is that there is a tremendous need to create some order in this growing data chaos that academia and industry produces, and then turn this into useful information, that could and should be turned into knowledge to be reasoned upon for the benefit of creating new intellectual, as well as fiscal wealth ([4], [5] , and [6] to [8]). The focus of this case is Rapid Prototyping (RP) processes and related knowledge management. This is an important area of science and technology that should be communicated to everybody who is involved in product innovation, product creation, product and process design, engineering management and advanced product marketing.

As the screen-prints in Figure 1 illustrate, the left hand side of the screen is usually hyperlinked text and small icons prompting student actions, with the fundamental text content. In the right hand side of the screen, we offer active code, animation clips, interactive videos in 2D and 3D, 3D objects, 360 degree panoramas and virtual facility tours, and others, that enhance the learning process, and together with the text, images and other media re-enforce the subject area. According to our experiences, such multi-facetted computing support in education offers a well-rounded experience, that is significantly more enjoyable to learn, than using traditional methods.

A typical screen segment of our browser readable, interactive 3D multimedia screens in the Case Based Learning Library. Figure 2 (below) illustrates further screen segments, that enable students to actively manipulate real-world virtual 3D rapid prototyped objects, and explore them according to their own interest. This approach keeps the students interested in the subject they learn, because they can actively interact with the computer, showing them exciting 3D interactive animations, and active code they can run with their own data, encouraging independence from their tutor.

Figure 2 illustrates several interactive 3D virtual reality objects, rapid prototyped propellers, that enable students to explore an-in-depth view of the discussed subject area. Summary and Conclusions The driving force behind our case-based learning method presented in this paper is the acceptance of the fact that industry needs hard working, well rounded, well educated,
