C# SolidWorks 二次开发 API—插入库特征
要想提高设计效率，做库特征是很常见的。例如我们下面这个视频，利用库特征在打了很多小孔。
利用库特征快速插入特征
这一次我们来看如何用代码插入库特征。
我们以API实例中的一个例子来说明一下过程：
public DispatchWrapper[] ObjectArrayToDispatchWrapperArray(object[] Objects)
{
int ArraySize = 0;
ArraySize = Objects.GetUpperBound(0);
DispatchWrapper[] d = new DispatchWrapper[ArraySize + 1];
int ArrayIndex = 0;
for (ArrayIndex = 0; ArrayIndex <= ArraySize; ArrayIndex++)
{
d[ArrayIndex] = new DispatchWrapper(Objects[ArrayIndex]);
}
return d;
}
public DispatchWrapper[] LibRefs;
private void btnInsertLibF_Click(object sender, EventArgs e)
{
ISldWorks swApp = Utility.ConnectToSolidWorks();
//可以参考API帮助中的:Create Library Feature Data Object and Library Feature With References Example (C#)
//Step1:新建一个零件.
