创建、修改和复制维度样式 （.NET）
通过创建对象的实例，然后将其添加到 with the 方法中，可以创建新的维度样式。在将维度样式添加到表中之前，请使用属性设置新样式的名称。DimStyleTableRecordDimStyleTableAddName 您还可以复制现有样式或具有覆盖的样式。使用该方法将维度样式从源对象复制到维度样式。源对象可以是另一个对象、 、 、 或对象，甚至可以是对象。如果从其他尺寸样式复制样式设置，则会完全复制当前样式。如果从 、 或对象复制样式设置，则当前设置（包括任何对象覆盖）将复制到该样式中。如果复制对象的当前样式，则尺寸样式以及任何绘图覆盖都将复制到新样式中。CopyFromDimStyleTableRecordDimensionToleranceLeaderDatabaseDimensionToleranceLeaderDatabase 复制维度样式和覆盖本示例创建三个新的尺寸样式，并将当前设置分别从当前、给定尺寸样式和给定尺寸复制到每个新尺寸样式。在运行此示例之前，按照相应的设置操作，您会发现已创建不同的尺寸样式。Database

使用 DIMSTYLE 命令打开维度样式管理器。现在应该已经列出了三维样式。样式 1 应具有黄色尺寸线。样式 2 应与样式 1 相同。样式 3 应具有蓝色尺寸线。 相关概念父主题： |
