https://blog.csdn.net/weixin_33933118/article/details/92346699 ObjectARX中对实体的操作一般有俩种方式,一种为open/close方式,另一种维通过事务的方式. 事务:通过程序对多个对象的多步操作集合成一个操作,如果事务操作成功,则对对象的操作成功,如果事务被中止,则取消对对象的操作,使用事务的好处是可以避免以上打开对象机制的限制. #define actrTransactionManager acTransactionManagerPtr() …
初始化透明度参数AcCmTransparency对象时,需要调用setAlpha设置透明度值,这里传入的值是0~255,但cad特性面板上显示的是0~90,且经过测试发现,传入值与特性面板显示的值也是不同的,比如传入90,显示64,百度搜索了个寂寞,最后还是在谷歌找到了答案,原来设置的值和特性面板显示的值有个转换关系:int alpha = (int)(((255 - value) * 100) / 255); 所以要在设置透明度之前把值做下转换,像这样 // 设置填充透明度 AcCmTransparency tr…
1、填充边界类型 外边界External。 内边界Outermost。 网上基本认为外边界是Outermost,内边界是Default,其实通过分析很容易知道CAD的原理。 hatch.NumberOfLoops 2 hatch.GetLoopAt(0).LoopType External hatch.GetLoopAt(1).LoopType Outermost 2、添加填充边界 添加边界AppendLoop,一次只能添加一条闭合边界,如果有多个怎么处理?通过循环依次添加。 // 添加外边界 for (int i…
