常见的百叶窗有圆形和多边形百叶窗两种 ,其中多边形百叶窗有三角形、五角形、六角形、八角形等几种 ,用作图或计算法就能很简捷地求出每个边的长度和所需要的角度 ,但要准确地在每个边上划出百叶板的刻槽位置线 ,就必须经过烦琐的计算 ,其计算的数值又很难准确地划在每个边的
There are two types of circular and polygonal shutters. The polygonal shutters are triangular, pentagonal, hexagonal and octagonal, so the length and length of each side can be easily calculated by using the graph or the calculation method However, to accurately draw the slab position line on each edge, it must be cumbersome calculation, the calculated value is difficult to accurately draw on each side of the
