求助：画spline线条出错。

程序代码如下：


void CreateSpline()<BR>{<BR>        AcGePoint3d point(0,0,0);<BR>        AcGePoint3dArray asd;<BR>        AcDbObjectId splineId;<BR>        AcDbBlockTableRecord *pBlockTableRecord;<BR>        AcDbBlockTable *pBlockTable;<BR>        <BR>        asd.append(point);<BR>        point.set(10,10,0);<BR>        asd.append(point);<BR>        point.set(20,-2,0);<BR>        asd.append(point);<BR>        point.set(30,5,0);<BR>        asd.append(point);<BR>        <BR>        AcDbSpline *pSpline=new AcDbSpline(asd,4,0.0);<BR>        Adesk::Boolean x=pSpline-&gt;isNull();<BR>                               acdbHostApplicationServices()-&gt;workingDatabase()-&gt;getSymbolTable(pBlockTable,AcDb::kForWrite);<BR>        pBlockTable-&gt;getAt(ACDB_MODEL_SPACE,pBlockTableRecord,AcDb::kForWrite);<BR>        Acad::ErrorStatus test=pBlockTableRecord-&gt;appendAcDbEntity(splineId,pSpline);<BR>        pBlockTable-&gt;close();<BR>        pBlockTableRecord-&gt;close();<BR>        pSpline-&gt;close();<BR>        delete pSpline;<BR>}


运行出现如下错误
