消除用VBA编程连续插入图块造成图形重叠的方法

在ＡｕｔｏＣＡＤ中，用ＶＢＡ编程实现图块连续插入时，如果编程中设置不当，会出现前后留块重叠的现象。本文详述了解决这种重叠现象的两种方法：１、删除构成图决对象中的图元方法；２、自动实现按不同名称定义图块的方法。最后，说明了两种方法的优缺点。关键词：##4ＶＢＡ;;ＡｃｔｉｖｅＸ技术;;图块对象;;图元

ELIMINATING THE SUPERPOSITION OF BLOCKS INSERTED CONTINUOLY BY VBA PROGRAMME

When some drawing blocks are inserted into the model space by the VBA programmein AutoCAD, inconsiderately, the programme will cause that a block inserted latter overlaps witha block foregoing. The paper has given two methods by which the superposition of the blocks issolved. These tWo methods are following: 1. Deleting entities in a block object; 2. While theprogramme running, the block name defining a block object is renamed atuomatically. Finally,the paper discusses the advantage and the disadvantage of the methods.
