}
我用acBlkTblRecs数组来记录acBlkTbl 中的每一个BlockTableRecord
我在图形中手工加入了一个块定义b1（只有一个圆），还在模型空间中画了一个圆，但是执行后我发现acBlkTblRecs只有4个成员
他们的base.name分别是*Model_Space,*PaperSpace,*PaperSpace0,b1,前面3个的layout属性都是ture。怎么没有那个圆所属的BlockTableRecord呢？
还有，我想查看b1中所有的图形定义，怎么查看呢？难道是通过acBlkTblRecs【3】，也就是b1的BlockBeginID,BlockEndID?
谢谢！
