对象

类型：属性

此属性适用的对象。

属性值

只读：不

类型：枚举acAttributeMode

• acAttributeModeNormal：指定保留每个属性的当前可见性。
• acAttributeModeInvisible：指定插入块时不显示属性值。ATTDISP 命令将覆盖不可见模式。
• acAttributeModeConstant：为属性提供块插入的固定值。
• acAttributeModeVerify：插入块时提示您验证属性值是否正确。
• acAttributeModeLockPosition：锁定属性的位置。
• acAttributeModeMultipleLine：允许属性延续到多行。
• acAttributeModePreset：插入包含预设属性的块时，将属性设置为其默认值。
