大家好，今天继续介绍我们的通用方法系列。
下面是今天要介绍的通用方法：
（1）这个通用方法为SW查找草图数量
/// <summary>
/// 查找草图数量
/// </summary>
/// <param name="doc2"></param>
/// <returns></returns>
public static int FindSketchesNumber(ModelDoc2 doc2)
{
FeatureManager featureManager = doc2.FeatureManager;
object[] features = (object[])featureManager.GetFeatures(true);
int sketchCount = 0;
// 遍历特征，统计3D草图的数量
foreach (object feature in features)
{
Feature swFeature = (Feature)feature;
if (swFeature.Name.Contains("3D草图"))
{
sketchCount++;
}
}
return sketchCount;
}
（2）这个通用方法为SW获取选择对象的Entity：
/// <summary>
/// 获取选择实体对象
/// </summary>
/// <param name="swModel">传入的ModelDoc2类型参数</param>
/// <returns></returns>
public static Entity EntityPlateSurface(ModelDoc2 swModel)
{
var swSelMgr = (SelectionMgr)swModel.SelectionManager;
var swEnt1 = (Entity)swSelMgr.GetSelectedObject6(1, -1);
return swEnt1;
}
（3）这个通用方法为SW获取选择对象的Component2：
/// <summary>
/// 获取选择对象的Component2
/// </summary>
/// <param name="swcomp1">传入的Component2类型参数</param>
/// <param name="swModel">传入的ModelDoc2类型参数</param>
/// <returns></returns>
public static Component2 GetEntityComponent(Component2 swcomp1, ModelDoc2 swModel)
{
bottomentity = null;
var swSelMgr = (SelectionMgr)swModel.SelectionManager;
swcomp1=(Component2)swSelMgr.GetSelectedObjectsComponent4(1,-1);
SelectData = swSelMgr.CreateSelectData();
bottonmodeldoc = (ModelDoc2)swcomp1.GetModelDoc2();
bottomentity = (Entity)swSelMgr.GetSelectedObject6(1, -1);
bottomid = swModel.Extension.GetPersistReference3(bottomentity);
return swcomp1;
}
今天要介绍的通用方法就是这么多，我们下篇文章再见。
