Drawing method for calculating arc radius according to arc length and chord length in CAD

The invention discloses a drawing method for calculating an arc radius according to an arc length and a chord length in CAD (Computer Aided Design). The drawing method comprises the following specific operations: deriving a formula, compiling a function module, compiling a function to establish a new function module, and outputting parameters after calling the function module to calculate the arc radius. According to the method, the arc radius is calculated through the operation of deriving the formula, writing the function module, writing the function and inputting the command, the arc radius is rapidly calculated according to the on-site arc object, a checking basis is provided for the site, data support is provided for subsequent construction, and the construction quality and the construction efficiency are improved. 本发明公开了一种在CAD中根据弧长和弦长计算圆弧半径的绘制方法，具体操作是推导公式、编写函数模块、编写函数建立新的功能模块，调用功能模块后输出参数进行圆弧半径的计算。本发明通过推导公式、编写函数模块、编写函数、输入命令的操作进行圆弧半径的计算，实现了根据现场弧形对象快速计算出圆弧半径，为现场提供校核依据以及后续施工提供数据支撑，提升施工质量和施工效率。
