object.ExtensionLineColor

对象

类型：暗三点角度，暗对齐，暗角，暗弧长度，暗坐标，暗旋转

此属性适用的对象。

属性值

只读：不

类型：枚举acColor

使用介于 0 到 256 之间的颜色索引号，或此处列出的常量之一：

• acByBlock
• acByLayer
• acRed
• acYellow
• acGreen
• acCyan
• acBlue
• acMagenta
• acWhite

言论

可以将颜色设置为数字索引值，范围从 0 到 256。为标准的七种颜色以及 BYBLOCK 和 BYLAYER 名称提供了常量。

如果使用，AutoCAD 将以默认颜色（白色或黑色，具体取决于您的配置）绘制新对象，直到它们被分组到块中。在图形中插入块时，块中的对象将继承颜色属性的当前设置。acByBlock

如果使用，新对象将采用绘制它们的图层的颜色。acByLayer
