在 CAD 二次开发过程中,很多函数/方法的参数要求输入的数据类型为Variant (array of objects),但在 Python 中似乎又没有哪一种数据类型与之直接相对应,若采用list代替Variant,那么程序无法顺利执行,报错为 “ 对象数组无效 ”。因此,需要某种转换方式,将Python中定义的变量转换为能够被CAD识别的数据类型Varia...

The current implementation keeps an array of integer objects for all integers between -5 and 256, when you create an int in that range you actually just get back a reference to the existing object. So it should be possible to change the value of 1. I suspect the behaviour of Python in...
