网友答: 高飞鸟的动态arx函数库
是目前最好的
可惜只支持到2014

CAD自带的arx函数库也挺好
没有版本问题
就是功能略简单

除此之外我试过的其它方法
包括各种dll和arx
都存在各种无法接受的硬伤
比如不支持按住鼠标中键平移视窗等

网友答: grread模拟动态
对大量图元的预览显示较慢
这是函数的硬伤
除此之外
最大的难点是实现捕捉
除了预置捕捉
还有右键捕捉菜单
和手输的临时指定捕捉
杜总的这个代码显然没有考虑这些
对需要精确定位的情况
就不是很合适了

网友答: 感谢分享，感谢杜总~~~~

网友答: 啊，大牛写的程序，菜鸡表示看不懂。

网友答: 按键没反应

网友答: 感谢杜总的分享！

网友答: 运行不起来呢

运行不起来呢

如果缺少函数，列出来，我补充，当然我很多帖子，可能函数在其他帖子里面有

网友答: 测试能运行的

网友答: 除了D键可以换基点，A、F、E、C键按了都没反应
