SldWorks swApp

//如果是安装单个版本的SW时
swApp = (SldWorks)Marshal.GetActiveObject("SldWorks.Application");

//如果是有多个版本的SW时，可能需要区分：
swApp = (SldWorks)Marshal.GetActiveObject("SldWorks.Application.26");//2018
swApp = (SldWorks)Marshal.GetActiveObject("SldWorks.Application.27");//2019
swApp = (SldWorks)Marshal.GetActiveObject("SldWorks.Application.28");//2020……

string filename = @"C:\WINDOWS\Temp\xxx.sldprt";

//打开方式 OpenDoc（文件路径，文件类型）
swApp.OpenDoc(filename, (int)swDocumentTypes_e.swDocPART);

//激活当前文件：
PartDoc swPart = (AssemblyDoc)swApp.ActiveDoc; 	   //类型1：零件
AssemblyDoc swAssy = (AssemblyDoc)swApp.ActiveDoc; //类型2：装配体
DrawingDoc swDraw = (AssemblyDoc)swApp.ActiveDoc;  //类型3：工程图

//打开装配体&获得当前装配体的零部件集合
public static string[] GetComps()
{
  AssemblyDoc swAssy = (AssemblyDoc)swApp.ActiveDoc;
  string[] Comppaths = (string[])swAssy.GetComponents(true);
  return Comppaths;
}

public static void GetSheetNames()
{
  //获取当前工程图对象
  Sheet drwSheet = (Sheet)swDraw.GetCurrentSheet();
  //获取当前工程图中的所有图纸名称
  object[] sheetNames = (object[])swDraw.GetSheetNames();
  //获取当前工程图中的所有图纸视图
  object[] views = (object[])drwSheet.GetViews();

  //遍历工程图零部件,输入选择视图,输出零部件名
  foreach (View view in views)
  {
    //选择视图激活
    DrawingComponent comp = view.RootDrawingComponent; Debug.Print(comp.Name);

    //获得子件对象
    object[] childrencomps = (object[])comp.GetChildren();

    //遍历工程图零部件
    for (int i = childrencomps.GetLowerBound(0); i <= childrencomps.GetUpperBound(0); i++)
    {
      Debug.Print("零部件是" + ((DrawingComponent)childrencomps[i]).Name);
    }
  }
}

// 遍历特征对象，根据特征名称找到特征对象来操作。
public static void TraverseFeatures(bool isTopLevel)
{
    //获得第一个特征，并赋值到当前特征curFeat
    Feature thisFeat = (Feature)swDoc.FirstFeature();
    Feature curFeat = default(Feature); curFeat = thisFeat;

    //当前特征非空就继续输出特征信息
    while ((curFeat != null))
    {
    /*——————/

    特征操作

    /——————*/

    //进入下一个特征
    Feature nextFeat = default(Feature);
    if (isTopLevel) { nextFeat = (Feature)curFeat.GetNextFeature(); }
    else { nextFeat = null; }
    curFeat = nextFeat; nextFeat = null;
    }
}

string PropertyName;//定义属性名
string PropertyValue;//定义属性值

//获得自定义属性对象（配置属性在双引号填[“配置名称”]）
CustomPropertyManager cusPropMgr = swDoc.Extension.CustomPropertyManager[""];

//获得属性：GetAll获得自定义属性内容，将obj转属性名数组
cusPropMgr.GetAll2(ref vPropNamesObject, ref vPropTypes, ref vPropValues, swCustomInfoGetResult_e.swCustomInfoGetResult_NotPresent);
object[] vPropNames = (object[])vPropNamesObject; if (vPropNames == null) { return; }


//增加属性：Add(属性名,类型,属性值,添加时的设置)
cusPropMgr.Add3(PropertyName, (int)swCustomInfoType_e.swCustomInfoText, PropertyValue, (int)swCustomPropertyAddOption_e.swCustomPropertyDeleteAndAdd);
//修改属性：
vPropNames[i]=”修改后的属性值”
//删除属性：
cusPropMgr.Delete2(PropertyName);
