With the increasing popularity of CAD technology, more and more research institutes and mines are faced with the problem of how to purchase CAD software, computers, and related drawing input/output systems suitable for themselves. In general, the first purchase should be a computer, CAD software and plotter. Conditional units can consider the configuration of engineering scanners and drawings processing and management software, large-format photocopiers and other equipment.
If you configure the desktop, the most common configuration should be: 200MHz clocked CPU, 64MB memory, 4.3G hard drive, 15-inch color display, S3 graphics card, 16x optical drive and PCI bus motherboard. If you consider establishing a local area network, you should purchase a workstation. PII266 and 300MHz processors are recommended for configuration, which will make the engineering design more convenient and fast. At the same time, in order to maintain the overall advantages, 128MB of memory, MGA professional graphics accelerator card, 4.3G or more hard disks should be used, and 17 inches of configuration should be considered. The above large screen display is better. It is worth mentioning that the large screen display on the PC can reduce the fatigue of the developer and help improve work efficiency. Display brand products mainly include: PHILIPS, SAMSUNG, SONY, and some domestic brands, including PHILIPS large-screen color display cost performance is very suitable for high-end microcomputer configuration.
Good CAD software is a key factor in increasing productivity and even increasing economic efficiency and the technological content of the products it develops. Therefore, it is very important to choose the right CAD software. In the face of fierce competition in foreign CAD software, domestic counterparts are not discouraged, have grown and matured in adversity, and have become industrialized and scaled up and have stood the test. Such as Daheng's mechanical CAD6.0 software. Most of these softwares are developed on the basis of AUTOCAD R12.0 or AUTOCAD R13.0. They have the advantages of practicality, high technical content, high integration, and low price, and are welcomed by users at home and abroad. Of course, some foreign CAD software also has many users in China, such as AUTODESK's mechanical CAD products. When buying these products, the main factors that should be considered are the following:
1. Whether purchased CAD products have current international advanced technologies, such as parametric, intelligent, visual, size-driven, three-view linkage, convenient three-dimensional mapping functions, rich and easy-to-use standard parts library, dynamic navigation and dynamic simulation, etc. .
2. What is the strength of the supplier of the product? Is there a stable and experienced development team that provides guarantees for its committed technical support and version upgrade?
3. Is it in line with the industry in which the unit is engaged? At present, there are more architectural and mechanical CAD products on the market. Other industries have CAD, such as electronic CAD and apparel CAD.
4. The operating environment of the software. In general, CAD based on WINDOWS is easy to learn and use, and it is also in line with contemporary trends.
Choosing a suitable plotter can be a headache. Because of the large number of plotters, the prices vary widely. In the field of plotters, foreign products have an absolute advantage, such as HP Designjet series plotters from Hewlett-Packard Company and XEROX plotters from Xerox Corporation in the US, which have many users in China. The overall impression is that HP's plotters are relatively expensive, while XEROX's is relatively low. Such as HP Designjet700 monochromatic inkjet plotter's main technical indicators are: the resolution is 600 × 600dpi, the maximum drawing format A0, length 15.2 meters, the buffer is configured as 4MB plus 1.5MB print memory, can be expanded to 68MB, with Expanded HPBi-Tronies parallel interface, RS-232C serial interface, built-in roller feed mechanism and automatic cutter.
The same type of XEROX products with the same technical specifications are priced 1/4 lower, and they can achieve color line printing. Both products provide the corresponding network card. XEROX's plotters are of small size and excellent price, and are favored by some users. Hewlett-Packard's plotters have won numerous users in the market with their long history, excellent technology and perfect service. Plotters from the earlier flat-panel pens to roller pens to today's ink-jet, drawing accuracy and speed greatly improved, and various auxiliary functions have gradually improved. The choice of plotter should be considered from the following aspects: (to be continued)
