Planning the transition from 2D to 3DAlthough less than 15% of CAD work has converted to 3D, the shift is gaining momentum as 3D CAD systems become more powerful, user-friendly, and affordable. 3D design and solid modeling technology can improve your analysis, design, manufacturing, and productivity while reducing the chance that models will require additional interpretation after completion. Understanding solid models In the 2D world, drawings are continually reinterpreted throughout a product's life cycle. With 3D technology, the solid model is the key element. While drawings are just a different way of representing the model, the solid model may be tested directly by using analysis tools. Removal of hidden lines and mass properties are automatic. Solid models enable better understanding of look and function before physical models are made. Consider standardizing specifications for building models, defining dimensions, using parts libraries, features, and naming files. Standard practices increase efficiency by making it easier to reuse models and implement changes. Solid modeling requires substantially more computer resources than 2D CAD. Insufficient memory can cause bottlenecking on your system's network. Will software support hardware features? Test software on platform alternatives and be sure to use your own data for testing. Implementing complementary software CAD tools are becoming easier to integrate with other CAD-related components but many ancillary products provided by CAD vendors may not keep pace with more general products for communications, data management, and viewing. Be sure to verify systems before buying. Understand your data flow. Are translations between processes required? If so, how are they done? Changing all the pieces of your process at once will create implementation challenges, but by developing pilot projects, you will learn as you go. Recognize that different parts of the process have different needs. The best design system may not be the best tool for a mold or tooling shop; changing all systems need not be done at the same time. Training & technical support Training should receive top priority. Although the investment in time and money may seem substantial, it will pay huge dividends in the long run by helping to ensure a smooth transition to different tools and processes. Inadequate training can often lead to productivity problems that are ultimately far more costly. An increasing number of 3D training options are available to CAD users. On-line and computer-based tutorials are available, and CAD software vendors are building simulated learning environments directly into the software. Alternate training and technical support resources include software, vendors, dealers, consultants, and in-house experts. The local value added reseller (VAR) can play a critical role in the training and implementation of new software. Handling legacy data The approach taken in handling legacy data depends on the source of solids software and form of your system. It is beneficial to use solid modeling software that supports the conversion of existing drawings to solids. [metlfax/incl/99mfx.htm] |
