1、实例一个AcGeMatrix3d 对象。

2、使用：

2. 
   
3. AcGeMatrix3d::setToScaling Function AcGeMatrix3d &
   
4. 
   
5. setToScaling(
   
6. 
   
7. double scaleAll,
   
8. 
   
9. const AcGePoint3d& center = AcGePoint3d::kOrigin);
   
10. 
    
11. scaleAll Input scale factor
    
12. center Input center point of the scale
    
13. 
    
14. Sets this matrix to the matrix of the uniform scaling by scale factor scaleAll
    
15. 
    
16. with respect to the point center.
    
17. 
    
18. Returns the reference to this matrix.
    
19. 
    

<br /> AcGeMatrix3d::setToScaling Function AcGeMatrix3d &<br /> <br /> setToScaling(<br /> <br /> double scaleAll,<br /> <br /> const AcGePoint3d& center = AcGePoint3d::kOrigin);<br /> <br /> scaleAll Input scale factor <br /> center Input center point of the scale <br /> <br /> Sets this matrix to the matrix of the uniform scaling by scale factor scaleAll <br /> <br /> with respect to the point center.<br /> <br /> Returns the reference to this matrix.<br /> <br />

设置缩放转换矩阵。

3、使用：AcDbEntity::transformBy 方法把缩放矩阵作用到实体上，就实现实体缩放了。

XDSoft 有没有完整的实例呢？本人功力不够，希望你能给个实例!
