在装配上下文中使用SOLIDWORKS API编辑特征
{ width=450 }
该示例演示了如何使用SOLIDWORKS API在装配上下文中修改特征定义。
宏中执行的步骤相当于在SOLIDWORKS用户界面中执行以下步骤:
- 选择包含拉伸特征的零件组件
- 在组件的上下文菜单中选择“编辑零件”菜单
- 选择拉伸特征并点击“编辑”命令
- 修改拉伸方向上的值
- 点击绿色勾号
- 退出编辑零件模式
在装配中编辑特征时,重要的是要遵循正确的装配上下文。
- 下面的示例是使用VSTA3宏实现的
- 在装配中选择零件组件
- 将拉伸特征的名称指定为EXTRUDE_FEAT_NAME变量的值
const string EXTRUDE_FEAT_NAME = "Boss-Extrude1";
- 运行宏。结果是将拉伸的值更改为EXTRUDE_DEPTH变量的值(以米为单位)
const double EXTRUDE_DEPTH = 0.02;
