请教如何修改线型?

backham

 AcDbCircle *pCir1;                      
 AcGePoint3d point1;                    
 AcGeVector3d nrm1=AcGeVector3d(0,0,1);    

 point1.x=500;point1.y=500;point1.z=0;

 pCir1=new AcDbCircle(point1,nrm1,da);  

 pBlockTableRecord->appendAcDbEntity(objId,pCir1);         
 pCir1->close();   
怎样把这个圆的线型改成虚线或者点划线

 麻烦说具体点,小弟是新学的

用以下的函数：

virtual Acad::ErrorStatus
setLinetype(
    const char* newVal,

    Adesk::Boolean doSubents = Adesk::kTrue);

newVal Input name of the LinetypeTableRecord to be referenced by the entity
doSubents Input Boolean indicating whether to propagate the change to any subentities the entity may own

不过要注意你要设置的线型要存在才有正确结果.
