There are firms that sell products as well as services to help run a business successfully.
Computer-Aided Design or CAD meets the design requirements of speedy revisions and accurate geometry, making the process of designing very easy. CAD was first used to design and manufacture aeroplanes and now has been developed to suit the needs of any kind of designers in any field of design and have user-friendly interfaces.
Types of CAD Software:
Software developers have benefited immensely by developing various CAD software. Various CAD software offer two-dimensional designs, as well as those offer three-dimensional designs. CAD has made it possible for two people in two remote corners of the world to design and create new products using CAD software as well as the Internet. Artists, mechanical, electronics and civil engineers, architects and interior decorators use CAD software to aid in their designing process.
2-D CAD software or go for more advanced 3-D CAD software. Some applications are inherently 2-D based. AutoCAD, Cadkey, CADDS 5, Medusa, and CATIA v4 are examples of 2D CAD software.
Pro / Engineer, Unigraphics NX, SolidWorks, Solid Edge, Autodesk Inventor, CoCreate Solid Designer, and VX CAD are popular 3D CAD software.
3D views are not very clear and are hard to visualize in 2D based CAD software. Here, designers some times used a physical scaled down model of the product to make corrections and changes if necessary. This is not the case in 3D CAD software where a clear view of the product can be obtained and quickening the design process. Making changes and corrections using 3D CAD software is easy as the design is automatically corrected, where as in 2D software the drawing may have to be recreated after changing or making corrections. 3D CAD software makes it easier to identify mistakes, inaccuracy in dimensions, interferences etc. Here, save time, energy and money. 3D CAD software designed products are reliable, fit and well designed. The time taken to design and finalize designs is significantly reduced when companies use 3D CAD software. Some software such as SolidWorks collaboration edition, 3D TeamWorks, is designed to help multiple people in different locations to work on one design using secure connections. Only a web browser and an internet connection is necessary making it possible to review designs and finalize them in real time.
It is essential for companies to analyze if they really need to upgrade to 3D CAD software, as they can be a cost and time-consuming process. While companies choose to upgrade to 3D CAD software it is essential to train personnel or hire new qualified and experienced personnel as it may take time to train existing personnel. However, it has to be acknowledged that designing industry has been helped immensely by using CAD software.
