things. The result is cleaner, less cluttered drawings. Another example of a productivity enhancement for drafting might involve automating auxiliary views of a design. By pressing the right button or by entering the right mand, a drawing could be turned 90 degrees in one direction or another. Threedimensional designs could be rotated on any axis or displayed in any of several projections. To take it one step further, remember that entire designs can be stored on the system. When the drafter receives a job that has specifications similar to a stored drawing, he merely retrieves it, brings it into working storage, and edits those portions of the design that are not consistent with the specifications of the new job. Productivity increases are thus pounded. The original job is speeded up, and that job, in turn, is used to speed up the next job even further. This illustrates the need to maintain a plete and uptodate data base that can be accessed easily by all users. IMPROVING DESIGN ANALYSIS Design analysis is another important task that can be handled automatically by a properly integrate CAD/CAM system. This is particularly important in an application like piping plant design where drawings are often plex and must adhere to precise industry specifications. A CAD/CAM system with piping design applications software can give the user automatic feedback on such characteristics as fluid capacities, material chemistry, stress limitations, and coupling requirements. It can also generate orthographic plans, elevation data, equipment parts lists, cost estimates, flow diagrams, process and instrumentation diagrams, and bills of materials. The system can even access and control plex engineering analysis programs and provide instant feedback on the viability of various design alternatives. OTHER ANALYTICAL BENEFITS CAD/CAM can influence a pany’s engineering systems in many other ways as well. It can streamline all physical processes, and permit reevaluation of current engineering methods and reporting procedures. CAD/CAM improves and expedites quality assurance techniques, and it lends itself naturally to maintaining accurate and plete documentation and to keeping accurate records of part numbers and bills of materials. WHAT ARE THE DRAWBACKS?。
