在工程设计中广泛使用各种各样的设计图表。一个设计良好的图表往往能使原来比较复杂的计算问题只用简单的工具(如直尺等)就能得出有足够精确度的结果,起到事半功倍的效果。对于从事专业工作的设计师来说,它是一个有用的工具,可以摆脱一些麻烦和重复的计算工作,提高工作效率。对于一些从事业余制作的爱好者来说,设计图表便成了有力的工具,在最短的时间内就可确定合适的设计方案。
Extensive use of a wide range of design charts in engineering design. A well-designed chart often makes the original more complex calculation problems can be obtained with the results of sufficient accuracy using only simple tools (such as straightedges, etc.), with a multiplier effect. It is a useful tool for designers engaged in professional work, to get rid of some troublesome and repetitive calculation work and improve work efficiency. For some amateurs in the production of amateur, the design of the chart has become a powerful tool in the shortest possible time to determine the appropriate design.
