獲取當前工程圖關聯的零件路徑：
c#

IModelDoc2 swModel;

IDrawingDoc swDraw;

swModel = swApp.ActiveDoc;

swDraw = (IDrawingDoc)swModel;

SolidWorks.Interop.sldworks.IView swView;  

string strPartPath="";

//根據工程圖配置得到其零件的路徑

swView = swDraw.GetFirstView();

while (swView == null||swView.GetReferencedModelName()==""
 
)
{
   swView = swView.GetNextView();
}

strPartPath = swView.GetReferencedModelName();
